Section 340.110  Radiation Protection Programs

 

a)         Each licensee or registrant shall develop, document, and implement a radiation protection program that ensures compliance with the provisions of this Part.  (See Section 340.1120 for recordkeeping requirements relating to these programs.)

 

b)         The licensee or registrant shall use, to the extent practicable, procedures and engineering controls based upon sound radiation protection principles to achieve occupational doses and public doses that are as low as is reasonably achievable (ALARA).

 

c)         The licensee shall review, at least annually, the radiation protection program content and implementation.

 

d)         To implement the ALARA requirements of Section 340.110(b) and notwithstanding the requirements in Section 340.310, a constraint on air emissions of radioactive materials to the environment, excluding radon-222 and its daughters, shall be established by licensees so that the individual member of the public likely to receive the highest dose will not be expected to receive a total effective dose equivalent (TEDE) in excess of 0.1 mSv (10 mrem) per year from these emissions.  If a licensee subject to this requirement exceeds this dose constraint, the licensee shall report the excess as provided in Section 340.1230 and promptly take appropriate corrective action to ensure against recurrence.

 

e)         The registrant shall review, at intervals not to exceed 1 inspection cycle as specified in 32 Ill. Adm. Code 320, the radiation protection program content and implementation.

Section 340.210  Occupational Dose Limits for Adults

 

a)         The licensee or registrant shall control the occupational dose to individual adults, except for planned special exposures pursuant to Section 340.260, to the following dose limits:

 

1)         An annual limit, which is the more limiting of:

 

A)        The total effective dose equivalent being equal to 0.05 Sv (5 rem); or

 

B)        The sum of the deep dose equivalent and the committed dose equivalent to any individual organ or tissue other than the lens of the eye being equal to 0.5 Sv (50 rem).

 

2)         The annual limits to the lens of the eye, to the skin and to the extremities which are:

 

A)        A lens dose equivalent of 0.15 Sv (15 rem); and

 

B)        A shallow dose equivalent of 0.5 Sv (50 rem) to the skin or to any extremity.

 

b)         Doses received in excess of the annual limits, including doses received during accidents, emergencies and planned special exposures, shall be subtracted from the limits for planned special exposures that the individual may receive during the current year and during the individual's lifetime (see Section 340.260(e)).

 

c)         When the external exposure is determined by measurement with an external personal monitoring device, the deep dose equivalent shall be used in place of the effective dose equivalent unless the effective dose equivalent is determined by a dosimetry method approved by the Agency.  The assigned deep dose equivalent shall be for the portion of the body receiving the highest exposure.  The assigned shallow dose equivalent shall be the dose averaged over the contiguous 10 square centimeters of skin receiving the highest dose.

 

AGENCY NOTE:  The deep dose equivalent, lens dose equivalent or shallow dose equivalent may be assessed from surveys or other radiation measurements for the purpose of demonstrating compliance with the occupational dose limits if the individual monitoring device was not in the region of highest potential exposure or the results of individual monitoring are unavailable. 

 

d)         The deep dose equivalent, lens dose equivalent and shallow dose equivalent may be assessed from surveys or other radiation measurements for the purpose of demonstrating compliance with the occupational dose limits, if the individual monitoring device was not in the region of highest potential exposure, or the results of individual monitoring are unavailable.

 

e)         Derived air concentration (DAC) and annual limit on intake (ALI) values are specified in table 1 of appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or editions, and may be used to determine the individual's dose (see Section 340.1160) and to demonstrate compliance with the occupational dose limits.

 

f)         Notwithstanding the annual dose limits, the licensee shall limit the soluble uranium intake by an individual to 10 milligrams in a week in consideration of chemical toxicity (see footnote 3 of appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or editions.)

 

g)         The licensee or registrant shall reduce the dose that an individual may be allowed to receive in the current year by the amount of occupational dose received while employed by any other person during the current year (see Section 340.250(a) and (d)).

 

AGENCY NOTE:  The purpose of this requirement is to ensure that no individual receives an annual occupational dose in excess of the occupational dose limits set forth in this Section.

Section 340.220  Compliance with Requirements for Summation of External and Internal Doses

 

a)         General Requirement.  If the licensee is required to monitor individual occupational dose pursuant to both Section 340.520(a) and (b) of this Part, the licensee shall demonstrate compliance with the dose limits by summing external and internal doses.  If the licensee or registrant is required to monitor individual occupational dose only pursuant to Section 340.520(a) of this Part or only pursuant to Section 340.520(b) of this Part, then summation is not required to demonstrate compliance with the dose limits.  The licensee may demonstrate compliance with the requirements for summation of external and internal doses pursuant to subsections (b), (c) and (d) of this Section.  The dose equivalents for the lens of the eye, the skin and the extremities are not included in the summation, but are subject to separate limits.

 

b)         Intake by Inhalation.  If the only intake of radionuclides is by inhalation, the total effective dose equivalent limit is not exceeded if the sum of the deep dose equivalent divided by the total effective dose equivalent limit, and one of the following, does not exceed unity:

 

1)         The sum of the fractions of the inhalation ALI for each radionuclide; or

 

2)         The total number of derived air concentration-hours (DAC-hours) for all radionuclides divided by 2,000; or

 

3)         The sum of the calculated committed effective dose equivalents to all significantly irradiated organs or tissues (T) calculated from bioassay data using biological models and expressed as a fraction of the annual limit.  For purposes of this requirement, an organ or tissue is deemed to be significantly irradiated if, for that organ or tissue, the product of the weighting factor (w_T) and the committed dose equivalent, H_T,50, per unit intake is greater than ten percent of the maximum weighted value of H_T,50 (i.e., w_TH_T,50) per unit intake for any organ or tissue.

 

c)         Intake by Oral Ingestion.  If the occupationally exposed individual receives an intake of radionuclides by oral ingestion greater than ten percent of the applicable oral ALI, the licensee shall account for this intake and include it in demonstrating compliance with the limits.

 

d)         Intake Through Wounds or Absorption Through Skin.  The licensee shall evaluate and, to the extent practicable, account for intakes through wounds or skin absorption.  The intake through intact skin has been included in the calculation of DAC for hydrogen-3 and does not need to be further evaluated or accounted for pursuant to this subsection.

Section 340.230  Determination of External Dose from Airborne Radioactive Material

 

a)         Licensees shall, when determining the dose from airborne radioactive material, include the contribution to the deep dose equivalent, lens dose equivalent and shallow dose equivalent from external exposure to the radioactive cloud (see footnotes 1 and 2 of appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007,  exclusive of subsequent amendments or editions).

 

b)         Airborne radioactivity measurements and DAC values shall not be used as the primary means to assess the deep dose equivalent when the airborne radioactive material includes radionuclides other than noble gases or if the cloud of airborne radioactive material is not relatively uniform.  The determination of the deep dose equivalent to an individual shall be based upon measurements using instruments or individual monitoring devices.

 

(Source:  Amended at 35 Ill. Reg. 934, effective December 30, 2010)

 

Section 340.240  Determination of Internal Exposure

 

a)         For purposes of assessing dose used to determine compliance with occupational dose equivalent limits, the licensee shall, when required pursuant to Section 340.520, take measurements of:

 

1)         Concentrations of radioactive materials in air in work areas during conditions of operations; or

 

2)         Quantities of radionuclides in the body after exposure to materials that could result in an intake; or

 

3)         Quantities of radionuclides excreted from the body after exposure to materials that could result in an intake; or

 

4)         Combinations of these measurements.

 

b)         Unless respiratory protective equipment is used, as provided in Section 340.730, or the assessment of intake is based on bioassays, the licensee shall assume that an individual inhales radioactive material at the airborne concentration in which the individual is present.

 

c)         When specific information on the physical and biochemical properties of the radionuclides taken into the body or the behavior of the material in an individual is known, the licensee may:

 

1)         Use that information to calculate the committed effective dose equivalent, and if used, the licensee shall document that information in the individual's record; and

 

2)         Upon prior approval of the Agency, adjust the DAC or ALI values to reflect the actual physical and chemical characteristics of airborne radioactive material (e.g., aerosol size distribution or density); and

 

3)         Separately assess the contribution of fractional intakes of Class D, W or Y compounds of a given radionuclide (see appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or editions) to the committed effective dose equivalent.

 

d)         If the licensee chooses to assess intakes of Class Y material using the measurements specified in subsections (a)(2) or (3), the licensee may delay the recording and reporting of the assessments for periods up to 7 months, unless otherwise required by Sections 340.1220 or 340.1230.

 

AGENCY NOTE:  This delay permits the licensee to make additional measurements basic to the assessments.

 

e)         If the identity and concentration of each radionuclide in a mixture are known, the fraction of the DAC applicable to the mixture for use in calculating DAC-hours shall be either:

 

1)         The sum of the ratios of the concentration to the appropriate DAC value (e.g., D, W or Y) from appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or editions, for each radionuclide in the mixture; or

 

2)         The ratio of the total concentration for all radionuclides in the mixture to the most restrictive DAC value for any radionuclide in the mixture.

 

f)         If the identity of each radionuclide in a mixture is known, but the concentration of one or more of the radionuclides in the mixture is not known, the DAC for the mixture shall be the most restrictive DAC of any radionuclide in the mixture.

 

g)         When a mixture of radionuclides in air exists, a licensee may disregard certain radionuclides in the mixture if:

 

1)         The licensee uses the total activity of the mixture in demonstrating compliance with the dose limits in Section 340.210 and in complying with the monitoring requirements in Section 340.520(b);

 

2)         The concentration of any radionuclide disregarded is less than 10 percent of its DAC; and

 

3)         The sum of these percentages for all of the radionuclides disregarded in the mixture does not exceed 30 percent.

 

h)         When determining the committed effective dose equivalent, the following information may be considered:

 

1)         In order to calculate the committed effective dose equivalent, the licensee may assume that the inhalation of one ALI, or an exposure of 2,000 DAC-hours, results in a committed effective dose equivalent of 0.05 Sv (5 rem) for radionuclides that have their ALIs or DACs based on the committed effective dose equivalent.

 

2)         For an ALI (and the associated DAC) determined by the nonstochastic organ dose limit of 0.5 Sv (50 rem), the intake of radionuclides that would result in a committed effective dose equivalent of 0.05 Sv (5 rem) (the stochastic ALI) is listed in parentheses in table 1 of appendix B to 10 CFR 20, published at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or editions.  The licensee may, as a simplifying assumption, use the stochastic ALI to determine committed effective dose equivalent.  However, if the licensee uses the stochastic ALI, the licensee shall also demonstrate that the limit in Section 340.210(a)(1)(B) is met.

Section 340.250  Determination of Prior Occupational Dose

 

a)         For each individual who may enter the licensee's or registrant's restricted area and is likely to receive, in a year, an occupational dose requiring monitoring pursuant to Section 340.520 of this Part, the licensee or registrant shall determine the occupational radiation dose received during the current year prior to allowing such individual to enter a restricted area.  In order to comply with this requirement, a licensee or registrant may accept, as a record of the occupational dose that the individual received during the current year, a written signed statement from the individual, or from the individual's most recent employers for work involving radiation exposure, that discloses the nature and the amount of any occupational dose that the individual may have received during the current year.  To accomplish this, a licensee or registrant may use the NRC Form 5 or submit equivalent information.

 

AGENCY NOTE:  Licensees and registrants also should attempt to obtain the records of cumulative occupational radiation dose.

 

b)         Prior to permitting an individual to participate in a planned special exposure, the licensee shall:

 

1)         Determine the cumulative occupational radiation dose.

 

A)        In order to comply with this requirement, a licensee may accept, as the record of cumulative radiation dose, an up-to-date NRC Form 4, or equivalent, signed by the individual and countersigned by an appropriate official of the most recent employer for work involving radiation exposure, or the individual's current employers (if the individual is not employed by the licensee); and

 

B)        Obtain reports of the individual's dose equivalent for the time period subsequent to that included in NRC Form 4, or equivalent, as specified in subsection (b)(1)(A) of this Section.  Such reports shall be signed by the individual and countersigned by an appropriate official of the most recent employers for work involving radiation exposure, or the individual's current employers (if the individual is not employed by the licensee).  The information shall be recorded on NRC Form 5, or equivalent.

 

2)         Determine the internal and external doses from all previous planned special exposures.

 

3)         Determine all doses in excess of the limits received during the lifetime of the individual, including doses received during accidents and emergencies.

 

c)         The licensee or registrant shall record the exposure history, as required by subsections (a) and (b) of this Section, on NRC Form 4 or 5, or equivalent, as applicable, or other clear and legible record containing all of the information required on that form.

 

1)         The form or record shall show each period in which the individual received occupational exposure to sources of radiation and shall be signed by the individual who received the exposure.  For each period for which the licensee or registrant obtains reports, the licensee or registrant shall use the dose shown in the report in preparing the exposure history.  For any period in which the licensee or registrant does not obtain a report, the licensee or registrant shall place a notation on the exposure history indicating the periods of time for which data are not available.

 

2)         For the purpose of complying with this requirement, licensees or registrants are not required to reevaluate the separate external dose equivalents and internal committed dose equivalents or intakes of radionuclides assessed before January 1, 1994.  Further, although occupational exposure histories obtained and recorded before January 1, 1994, would not have included effective dose equivalent, such histories may be used in the absence of specific information on the intake of radionuclides by the individual.

 

d)         If the licensee or registrant is unable to obtain a complete record of an individual's current and previously accumulated occupational dose, the licensee or registrant:

 

1)         When establishing administrative controls pursuant to Section 340.210(g) of this Part for the current year, shall assume that the allowable dose limit for the individual is reduced by 12.5 mSv (1.25 rem) for each calendar quarter for which records were unavailable and the individual was engaged in activities that could have resulted in occupational radiation exposure; and

 

2)         Shall not authorize the individual to receive any planned special exposures.

 

e)         Records shall be retained in accordance with the requirements of Section 340.1140(a) of this Part.

Section 340.260  Planned Special Exposures

 

A licensee may authorize an adult worker to receive doses in addition to, and accounted for separately from, the doses received under the limits specified in Section 340.210 of this Part, provided that each of the following conditions are satisfied:

 

a)         The licensee authorizes a planned special exposure only in an exceptional situation when alternatives that might avoid the dose estimated to result from the planned special exposure are unavailable or impractical.

 

b)         The management official of the licensee and employer, if the employer is not the licensee, specifically authorize the planned special exposure, in writing, before the exposure occurs.

 

c)         Before a planned special exposure, the licensee ensures that each individual involved is:

 

1)         Informed of the purpose of the planned operation; and

 

2)         Informed of the estimated doses and associated potential risks and specific radiation levels or other conditions that might be involved in performing the task; and

 

3)         Instructed in the measures to be taken to keep the dose ALARA considering other risks that may be present.

 

d)         Prior to permitting an individual to participate in a planned special exposure, the licensee ascertains previous doses received during the lifetime of the individual as required by Section 340.250(b) of this Part.

 

e)         Subject to Section 340.210(b) of this Part, the licensee shall not authorize a planned special exposure that would cause an individual's dose from all planned special exposures and all doses in excess of the limits to exceed:

 

1)         The numerical values of any of the dose limits in Section 340.210(a) of this Part in any year; and

 

2)         Five times the annual dose limits in Section 340.210(a) of this Part during the individual's lifetime.

 

f)         The licensee maintains records of the conduct of a planned special exposure in accordance with Section 340.1150 of this Part and submits a written report in accordance with Section 340.1240 of this Part.

 

g)         The licensee records the best estimate of the dose resulting from the planned special exposure in the individual's record and informs the individual, in writing, of the dose within 30 days from the date of the planned special exposure.  The dose from planned special exposure need not be considered in controlling future occupational dose of the individual pursuant to Section 340.210(a) of this Part but shall be included in evaluations required by subsections (d) and (e) of this Section.

Section 340.280  Dose Equivalent to an Embryo/Fetus

 

a)         Except as otherwise provided in subsections (d) and (e) of this Section, the licensee or registrant shall ensure that the dose equivalent to an embryo/fetus during the entire pregnancy, due to occupational exposure of a declared pregnant woman, does not exceed 5 mSv (0.5 rem).  (For recordkeeping requirements, see Section 340.1160(d) of this Part.)

 

b)         The dose equivalent to an embryo/fetus shall be taken as the sum of:

 

1)         The deep dose equivalent to the declared pregnant woman during the entire pregnancy; and

 

2)         The dose equivalent to the embryo/fetus from radionuclides in the embryo/fetus and radionuclides in the declared pregnant woman during the entire pregnancy.

 

c)         The licensee or registrant shall make efforts to avoid substantial variation above a uniform monthly exposure rate to a declared pregnant woman so as to satisfy the limit in subsection (a) of this Section.

 

AGENCY NOTE:  The National Council on Radiation Protection and Measurements report entitled "Recommendations on Limits for Exposure to Ionizing Radiation", NCRP 91, published June 1, 1987, recommends that no more than 0.5 mSv (0.05 rem) of the allowed dose to the embryo/fetus be received during any one month during a declared pregnancy.

 

d)         If the declared pregnant woman has not notified the licensee or registrant of the estimated date of conception, the licensee or registrant shall ensure that the dose equivalent to an embryo/fetus, as specified in subsection (b) of this Section, due to occupational exposure of the declared pregnant woman does not exceed 0.5 mSv (0.05 rem) per month, during the remainder of the pregnancy.  If after initially declaring her pregnancy, a declared pregnant woman advises the licensee or registrant of the estimated date of conception, the dose limits specified in subsections (a) and (e) of this Section shall apply.

 

AGENCY NOTE:  The Agency encourages licensees and registrants to explain to declared pregnant workers that providing an estimated date of conception will enable the licensee or registrant to more accurately assess the radiation dose equivalent to the embryo/fetus and assist the licensee or registrant in determining appropriate precautions to be taken for the remainder of the pregnancy.

 

e)         If by the time the woman informs the licensee or registrant of the estimated date of conception the dose equivalent to the embryo/fetus has exceeded 4.5 mSv (0.45 rem), the licensee or registrant shall be deemed to be in compliance with subsection (a) of this Section if the additional dose equivalent to the embryo/fetus as specified in subsection (b) of this Section does not exceed 0.5 mSv (0.05 rem) during the remainder of the pregnancy.

4)         Sealed sources containing only hydrogen-3;

 

5)         Seeds of iridium-192 encased in nylon ribbon;

 

6)         Sealed sources, except teletherapy and brachytherapy sources, that are stored, not being used and identified as in storage.  The licensee shall, however, test each such sealed source for leakage or contamination and receive the test results that confirm that the sealed source is not leaking or contaminated before any use or transfer unless it has been tested for leakage or contamination within 6 months for beta and gamma emitting sources, or within 3 months for sources designed to emit alpha particles, before the date of use or transfer; and

 

7)         Sealed sources distributed under a license issued pursuant to 32 Ill. Adm. Code 330.280(m), but only if the evaluation sheet for those sealed sources, as filed in the "Radioactive Material Reference Manual" maintained by the Department of Health and Human Services or in the "Registry of Radioactive Sealed Sources and Devices" maintained by the U.S. Nuclear Regulatory Commission, specifies that testing for leakage or contamination is not required.

 

c)         Tests for leakage or contamination from sealed sources shall be performed by persons specifically authorized by the Agency, an Agreement State, a Licensing State or the Nuclear Regulatory Commission to perform such services.

 

d)         Test results shall be kept as specified in Section 340.1135 of this Part.

 

e)         The following shall be considered evidence that a sealed source is leaking:

 

1)         The presence of 185 Bq (0.005 µCi) or more of removable contamination on any test sample.

 

2)         Leakage of 37 Bq (0.001 µCi) of radon-222 per 24 hours for brachytherapy sources manufactured to contain radium.

 

3)         The presence of removable contamination resulting from the decay of 185 Bq (0.005 µCi) or more of radium.

 

f)         The licensee shall immediately withdraw a leaking or contaminated sealed source from use and shall take action to prevent the spread of contamination.  The leaking or contaminated sealed source shall be repaired, decontaminated or disposed of in accordance with this Part.

 

g)         Reports of test results for leaking or contaminated sealed sources shall be made pursuant to Section 340.1260 of this Part.

(Source:  Amended at 29 Ill. Reg. 20841, effective December 16, 2005)

 

Section 340.630  Control of Access to Very High Radiation Areas – Irradiators

 

a)         This Section applies to licensees or registrants with sources of radiation in irradiators that are not self-shielded.  This Section does not apply to sources of radiation that are used in teletherapy, in industrial radiography or in completely self-shielded irradiators in which the source is both stored and operated within the same radiation shielding barrier and, in the designed configuration of the irradiator, is always physically inaccessible to any individual and cannot create a radiation level of 5 Gy (500 rad) or more in 1 hour at 1 meter in an area that is accessible to any individual.

 

b)         Each area in which there may exist radiation levels in excess of 5 Gy (500 rad) in 1 hour at 1 meter from a source of radiation that is used to irradiate matter shall meet the following requirements:

 

1)         Each entrance or access point shall be equipped with entry control devices that:

 

A)        Function automatically to prevent any individual from inadvertently entering a very high radiation area;

 

B)        Permit deliberate entry into the area only after a control device is actuated that causes the radiation level within the area, from the source of radiation, to be reduced below that at which it would be possible for an individual to receive a deep dose equivalent in excess of 1 mSv (0.1 rem) in 1 hour; and

 

C)        Prevent operation of the source of radiation if it would produce radiation levels in the area that could result in a deep dose equivalent to an individual in excess of 1 mSv (0.1 rem) in 1 hour.

 

2)         Additional control devices shall be provided so that, upon failure of the entry control devices to function as required by subsection (b)(1) of this Section:

 

A)        The radiation level within the area, from the source of radiation, is reduced below that at which it would be possible for an individual to receive a deep dose equivalent in excess of 1 mSv (0.1 rem) in 1 hour; and

 

B)        Conspicuous visible and audible alarm signals are generated to make an individual attempting to enter the area aware of the hazard.  The alarm signals shall be located so that at least one other authorized individual, who is physically present, familiar with the activity, and prepared to render or summon assistance, is made aware of the failure of the entry control devices.

 

3)         The licensee or registrant shall provide control devices so that, upon failure or removal of any physical radiation barriers, other than the shielded storage container for sealed sources:

 

A)        The radiation level from the source of radiation is reduced below that at which it would be possible for an individual to receive a deep dose equivalent in excess of 1 mSv (0.1 rem) in 1 hour; and

 

B)        Conspicuous visible and audible alarm signals are generated to make potentially affected individuals aware of the hazard and the licensee or registrant or at least one other individual, who is familiar with the activity and prepared to render or summon assistance, aware of the failure or removal of the physical barrier.

 

4)         When the shield for the stored sealed source is a liquid, the licensee shall provide means to monitor the integrity of the shield and to signal, automatically, loss of adequate shielding.

 

5)         Physical radiation barriers that comprise permanent structural components, such as walls, that have no credible probability of failure or removal in ordinary circumstances need not meet the requirements of subsections (b)(3) and (4) of this Section.

 

6)         Each area shall be equipped with devices that will automatically generate conspicuous visible and audible alarm signals to alert personnel in the area before the source of radiation can be put into operation and in time for any individual in the area to operate a clearly identified control device, which must be installed in the area and that can prevent the source of radiation from being put into operation.

 

7)         Each area shall be controlled by use of devices and administrative procedures that ensure that the area is cleared of personnel prior to each use of the source of radiation.

 

8)         Each area shall be checked by a radiation measurement to ensure that, prior to the first individual's entry into the area after any use of the source of radiation, the radiation level from the source of radiation in the area is below that at which it would be possible for an individual to receive a deep dose equivalent in excess of 1 mSv (0.1 rem) in 1 hour.

 

9)         The entry control devices required in subsection (b)(1) of this Section shall be tested for proper functioning (see Section 340.1190 of this Part for recordkeeping requirements).

 

A)        Testing shall be conducted prior to initial operation with the source of radiation on any day, unless operations were continued uninterrupted from the previous day;

 

B)        Testing shall be conducted prior to resumption of operation of the source of radiation after any unintentional interruption; and

 

C)        The licensee or registrant shall submit and adhere to a schedule for periodic tests of the entry control and warning systems.

 

10)          The licensee or registrant shall not conduct operations, other than those necessary to place the source of radiation in safe condition or to effect repairs on controls, unless control devices are functioning properly.

 

11)          Entry and exit portals that are used in transporting matter to and from the irradiation area, and that are not intended for use by individuals, shall be controlled by such devices and administrative procedures as are necessary to physically protect and warn against inadvertent entry by any individual through these portals.  Exit portals for irradiated matter shall be equipped to detect and signal the presence of any loose sealed sources that are carried toward such an exit and to automatically prevent loose sealed sources from being carried out of the area.

 

c)         Registrants, licensees or applicants for licenses for sources of radiation that are within the purview of subsection (b) of this Section and that will be used in a variety of positions or in locations (e.g., open fields or forests) that make it impracticable to comply with certain requirements of subsection (b) of this Section, such as those for the automatic control of radiation levels, may apply to the Agency for approval of alternative safety measures.  Alternative safety measures shall provide personnel protection at least equivalent to those specified in subsection (b) of this Section.  At least one of the alternative measures shall include an entry-preventing interlock control based on a measurement of the radiation that ensures the absence of high radiation levels before an individual can gain access to the area where such sources of radiation are used.

Section 340.730  Use of Individual Respiratory Protection Equipment

 

a)         If the licensee assigns or permits the use of respiratory protection equipment to limit the intake of radioactive material then:

 

1)         Except as provided in subsection (a)(2), the licensee shall use only respiratory protection equipment that is tested and certified by the National Institute for Occupational Safety and Health (NIOSH).

 

2)         The licensee may use equipment that has not been tested or certified by NIOSH, or for which there is no schedule for testing or certification, provided the Agency has approved an application for authorized use of that equipment. The application shall include evidence that the material and performance characteristics of the equipment are capable of providing the proposed degree of protection under anticipated conditions of use.  This shall be demonstrated either by licensee testing or on the basis of reliable test information.

 

3)         The licensee shall implement and maintain a respiratory protection program that includes:

 

A)        Air sampling sufficient to identify the potential hazard, permit proper equipment selection, and estimate doses.

 

B)        Surveys and bioassays, as necessary, to evaluate actual intakes.

 

C)        Testing of respirators for operability (user seal check for face sealing devices and functional check for others) immediately prior to each use.

 

D)        Written procedures regarding:

 

i)          Monitoring, including air sampling and bioassays;

 

ii)         Supervision and training of respirator users;

 

iii)        Fit testing;

 

iv)        Respirator selection;

 

v)         Breathing air quality;

ix)        Limitations on periods of respirator use and relief from respirator use.

 

E)        Determination by a physician that the individual user is medically fit to use respiratory protection equipment:

 

i)          Before the initial fitting of a face sealing respirator;

 

ii)         Before the first field use of non-face sealing respirators; and

 

iii)        Either every 12 months thereafter or periodically at a frequency determined by a physician.

 

F)         Fit testing, with a fit factor > 10 times the APF for negative pressure devices, and a fit factor > 500 for any positive pressure, continuous flow, and pressure-demand devices, before the first field use of tight fitting, face-sealing respirators and periodically thereafter at a frequency not to exceed 1 year. Fit testing must be performed with the facepiece operating in the negative pressure mode.

 

4)         The licensee shall advise each respirator user that the user may leave the area at any time for relief from respirator use in the event of equipment malfunction, physical or psychological distress, procedural or communication failure, significant deterioration of operating conditions, or any other conditions that might require such relief.

 

5)         The licensee shall consider limitations appropriate to the type and mode of use. When selecting respiratory devices the licensee shall provide for vision correction, adequate communication, low temperature work environments, and the concurrent use of other safety or radiological protection equipment. The licensee shall use equipment in such a way as not to interfere with the proper operation of the respirator.

 

6)         Standby rescue persons are required whenever one-piece atmosphere-supplying suits, or any combination of supplied air respiratory protection device and personnel protective equipment are used from which an unaided individual would have difficulty extricating himself or herself. The standby persons shall be equipped with respiratory protection devices or other apparatus appropriate for the potential hazards. The standby rescue persons shall observe or otherwise maintain continuous communication with the workers (visual, voice, signal line, telephone, radio, or other suitable means), and be immediately available to assist them in case of a failure of the air supply or for any other reason that requires relief from distress. A sufficient number of standby rescue persons shall be immediately available to assist all users of this type of equipment and to provide effective emergency rescue if needed.

 

7)         Atmosphere-supplying respirators must be supplied with respirable air of grade D quality or better as defined by the Compressed Gas Association in publication G-7.1, "Commodity Specification for Air", 1997 and included in the regulations of the Occupational Safety and Health Administration at 29 CFR 1910.134(i)(1)(ii)(A) through (E) (2019). Grade D quality air criteria include:

 

i)          Oxygen content (v/v) of 19.5-23.5%;

 

ii)         Hydrocarbon (condensed) content of 5 milligrams per cubic meter of air or less;

 

iii)        Carbon monoxide (CO) content of 10 ppm or less;

 

iv)        Carbon dioxide content of 1,000 ppm or less; and

 

v)         Lack of noticeable odor.

b)         When estimating the dose to individuals from intake of airborne radioactive materials, the concentration of radioactive material in the air that is inhaled when respirators are worn is initially assumed to be the ambient concentration in air without respiratory protection, divided by the assigned protection factor.  If the dose is later found to be greater than the estimated dose, the corrected value shall be used; if the dose is later found to be less than the estimated dose, the corrected value may be used.  Protection factors for respirators are specified in Appendix A to 10 CFR 20 (1999).

 

c)         The licensee shall obtain authorization from the Agency before using assigned protection factors in excess of those specified in Appendix A to 10 CFR 20 (1999).  The Agency may authorize a licensee to use higher assigned protection factors on receipt of an application that:

 

1)         Describes the situation for which a need exists for higher protection factors; and

 

2)         Demonstrates that the respiratory protection equipment provides these higher protection factors under the proposed conditions of use.

 

d)         The Agency may impose restrictions in addition to the provisions of this Section, Section 340.720, and Appendix A to 10 CFR 20 (1999) in order to ensure the respiratory protection program of the licensee is adequate to limit doses to individuals from intakes of airborne radioactive materials consistent with maintaining total effective dose equivalent ALARA and limit the extent to which a licensee may use respiratory protection equipment instead of process or other engineering controls.

Section 340.1052  Classification of Radioactive Waste for Land Disposal

 

a)         Considerations.  Determination of the classification of radioactive waste involves two considerations.  First, consideration must be given to the concentration of long-lived radionuclides (and their shorter-lived precursors) whose potential hazard will persist long after such precautions as institutional controls, improved waste form and deeper disposal have ceased to be effective.  These precautions delay the time when long-lived radionuclides could cause exposures.  In addition, the magnitude of the potential dose is limited by the concentration and availability of the radionuclide at the time of exposure.  Second, consideration must be given to the concentration of shorter-lived radionuclides for which requirements on institutional controls, waste form and disposal methods are effective.

 

b)         Classes of waste.

 

1)         Class A waste is waste that is usually segregated from other waste classes at the disposal site.  The physical form and characteristics of Class A waste must meet the minimum requirements set forth in Section 340.1055(a) of this Part.  If Class A waste also meets the stability requirements set forth in Section 340.1055(b) of this Part, it is not necessary to segregate the waste for disposal.

 

2)         Class B waste is waste that must meet more rigorous requirements on waste form to ensure stability (as defined in 32 Ill. Adm. Code 601.20) after disposal.  The physical form and characteristics of Class B waste must meet both the minimum and stability requirements set forth in Section 340.1055 of this Part.

 

3)         Class C waste is waste that not only must meet more rigorous requirements on waste form to ensure stability but also requires additional measures at the disposal facility to protect against inadvertent intrusion.  The physical form and characteristics of Class C waste must meet both the minimum and stability requirements set forth in Section 340.1055 of this Part.

 

c)         Classification determined by long-lived radionuclides.  If the radioactive waste contains only radionuclides listed in Table 1 of this Section, classification shall be determined as follows:

 

1)         If the concentration does not exceed 0.1 times the value in Table 1, the waste is Class A.

 

2)         If the concentration exceeds 0.1 times the value in Table 1, but does not exceed the value in Table 1, the waste is Class C.

 

3)         If the concentration exceeds the value in Table 1, the waste is not generally acceptable for land disposal.

 

4)         For wastes containing mixtures of radionuclides listed in Table 1, the total concentration shall be determined by the sum of fractions rule described in subsection (g) of this Section.

 

Table 1
Radionuclide	Concentration curies/cubic meter
C-14	8
C-14 in activated metal	80
Ni-59 in activated metal	220
Nb-94 in activated metal	0.2
Tc-99	3
I-129	0.08
Alpha emitting transuranic radionuclides with half-life greater than five years	100
Pu-241	3,500
Cm-242	20,000
Ra-226	100

 

AGENCY NOTE:  Units are nanocuries per gram.

 

d)         Classification determined by short-lived radionuclides.  If the waste does not contain any of the radionuclides listed in Table 1, classification shall be determined based on the concentrations shown in Table 2 of this Section.  However, as specified in subsection (f) of this Section, if radioactive waste does not contain any nuclides listed in either Table 1 or Table 2, it is Class A.

 

1)         If the concentration does not exceed the value in Column 1, the waste is Class A.

 

2)         If the concentration exceeds the value in Column 1 but does not exceed the value in Column 2, the waste is Class B.

 

3)         If the concentration exceeds the value in Column 2 but does not exceed the value in Column 3, the waste is Class C.

 

4)         If the concentration exceeds the value in Column 3, the waste is not generally acceptable for near-surface disposal.

 

5)         For wastes containing mixtures of the radionuclides listed in Table 2, the total concentration shall be determined by the sum of fractions rule described in subsection (g) of this Section.

 

Table 2
Radionuclide	Concentration (curies/cubic meter)
	Column 1	Column 2	Column 3
Total of all radionuclides with less than 5-year half-life	700	–	–
H-3	40	–	–
Co-60	700	–	–
Ni-63	3.5	70	700
Ni-63 in activated metal	35	700	7000
Sr-90	0.04	150	7000
Cs-137	1	44	4600

 

AGENCY NOTE:  There are no limits established for these radionuclides in Class B or C wastes.  Practical considerations such as the effects of external radiation and internal heat generation on transportation, handling and disposal will limit the concentrations for these wastes.  These wastes shall be Class B unless the concentrations of other radionuclides in Table 2 determine the waste to be Class C independent of these radionuclides.

 

e)         Classification determined by both long- and short-lived radionuclides.  If the radioactive waste contains a mixture of radionuclides, some of which are listed in Table 1 and some of which are listed in Table 2, classification shall be determined as follows:

 

1)         If the concentration of a radionuclide listed in Table 1 is less than 0.1 times the value listed in Table 1, the class shall be that determined by the concentration of radionuclides listed in Table 2.

 

2)         If the concentration of a radionuclide listed in Table 1 exceeds 0.1 times the value listed in Table 1, but does not exceed the value in Table 1, the waste shall be Class C, provided the concentration of radionuclides listed in Table 2 does not exceed the value shown in Column 3 of Table 2.

 

f)         Classification of wastes with radionuclides other than those listed in Tables 1 and 2.  If the waste does not contain any radionuclides listed in either Tables 1 or 2, it is Class A.

 

g)         The sum of the fractions rule for mixtures of radionuclides.  For determining classification for waste that contains a mixture of radionuclides, it is necessary to determine the sum of fractions by dividing each radionuclide's concentration by the appropriate limit and adding the resulting values.  The appropriate limits must all be taken from the same column of the same table.  The sum of the fractions for the column must be less than 1.0 if the waste class is to be determined by that column.  Example:  A waste contains Sr-90 in a concentration of 50 Ci/m3 and Cs-137 in a concentration of 22 Ci/m3. Since the concentrations both exceed the values in Column 1, Table 2, they must be compared to Column 2 values.  For Sr-90 fraction, 50/150 = 0.33, for Cs-137 fraction, 22/44 = 0.5; the sum of the fractions = 0.83.  Since the sum is less than 1.0, the waste is Class B.

 

h)         Determination of concentrations in wastes.  The concentration of a radionuclide may be determined by indirect methods such as use of scaling factors which relate the inferred concentration of one radionuclide to another that is measured, or radionuclide material accountability, if there is reasonable assurance that the indirect methods can be correlated with actual measurements.  The concentration of a radionuclide may be averaged over the volume of the waste, or weight of the waste if the units are expressed as nano-curies per gram.

Section 340.1055  Radioactive Waste Characteristics

 

a)         The following are minimum requirements for all classes of waste and are intended to facilitate handling and provide protection of health and safety of personnel at the disposal site.

 

1)         Wastes shall be packaged in conformance with the conditions of the license issued to the site operator to which the waste will be shipped.  Where the conditions of the site license are more restrictive than the provisions of this Part, the site license conditions shall govern.

 

2)         Wastes shall not be packaged for disposal in cardboard or fiberboard boxes.

 

3)         Liquid waste shall be packaged in sufficient absorbent material to absorb twice the volume of the liquid.

 

4)         Solid waste containing liquid shall contain as little free-standing and non-corrosive liquid as is reasonably achievable, but in no case shall the liquid exceed 1% of the volume.

 

5)         Waste shall not be readily capable of detonation or of explosive decomposition or reaction at normal pressures and temperatures, or of explosive reaction with water.

 

6)         Waste shall not contain, or be capable of generating, quantities of toxic gases, vapors, or fumes harmful to persons transporting, handling, or disposing of the waste.  This does not apply to radioactive gaseous waste packaged in accordance with subsection (a)(8).

 

7)         Waste must not be pyrophoric.  Pyrophoric materials contained in wastes shall be treated, prepared, and packaged to be nonflammable.

 

8)         Wastes in a gaseous form shall be packaged at an absolute pressure that does not exceed 1.5 atmospheres at 20°C (68°F).  Total activity shall not exceed 100 Ci per container.

 

9)         Wastes containing hazardous, biological, pathogenic, or infectious material shall be treated to reduce to the maximum extent practicable the potential hazard from the non-radiological materials.

 

b)         The following requirements are intended to provide stability of the waste. Stability is intended to ensure that the waste does not degrade and affect overall stability of the site through slumping, collapse, or other failure of the disposal unit and thereby lead to water infiltration.  Stability is also a factor in limiting exposure to an inadvertent intruder, since it provides a recognizable and nondispersible waste.

 

1)         Waste shall have structural stability.  A structurally stable waste form will generally maintain its physical dimensions and its form, under the expected disposal conditions such as weight of overburden and compaction equipment, the presence of moisture, and microbial activity, and internal factors such as radiation effects and chemical changes.  Structural stability can be provided by the waste form itself, processing the waste to a stable form, or placing the waste in a disposal container or structure that provides stability after disposal.

 

2)         Notwithstanding the provisions in subsections (a)(3) and (a)(4), liquid wastes, or wastes containing liquid, shall be converted into a form that contains as little free-standing and non-corrosive liquid as is reasonably achievable, but in no case shall the liquid exceed 1% of the volume of the waste when the waste is in a disposal container designed to ensure stability, or 0.5% of the volume of the waste for waste processed to a stable form.

 

3)         Void spaces within the waste and between the waste and its package shall be reduced to the extent practicable.
