PART 5. STANDARDS FOR PROTECTION AGAINST RADIATION R 325.5201 Purpose and scope.

Page 39 Courtesy of www.michigan.gov/orr

Rule 201. (1) This part establishes standards for protection against radiation hazards. Except as otherwise specifically provided this part applies to all licensees and registrants.

(2) In addition to complying with requirements in this part, every reasonable effort should be made to maintain radiation levels in unrestricted areas and releases of radioactive materials in effluents to unrestricted areas, as far below the limits specified in this part as practicable. The term "as far below the limits specified in this part as practicable" means as low as is practicably achievable, taking into account the state of technology, and the economics of improvements in relation to benefits to the public health and safety and in relation to the use of sources of radiation in the public interest.

History: 1979 AACS; 2016 AACS. R 325.5202 Intentional exposure of humans. Rule 202. (1) Nothing in these rules shall be construed as limiting the intentional exposure

of patients to radiation for the purpose of medical diagnosis, medical therapy, or medical research conducted by licensed members of the healing arts.

(2) Intentional exposure of individuals to radiation or concentrations of radioactive material for diagnostic or therapeutic purposes shall be limited to supervision or prescriptions by licensed members of the healing arts.

History: 1979 AACS; 2016 AACS.

PERMISSIBLE DOSES, LEVELS AND CONCENTRATIONS R 325.5203 Exposure of individuals to radiation. Rule 203. (1) Except as provided in subrules (3),(4), and (6) of this rule, a licensee or

registrant shall not receive, possess, use, or transfer sources of radiation in a manner as to cause any individual to receive in any period from all sources of radiation in the licensee's or registrant's possession a dose in excess of the limits specified in table 1 of Rule 205. A licensee or registrant shall not be held liable for meeting the dose limit for fertile women (with respect to fetus) listed in table 1 until and unless the employee has submitted written notice to the licensee or registrant of the pregnant condition. Potential risk of exposure, if any, to the fetus before the written notice is received shall be assumed by the employee as a condition of employment as a radiation worker. Following receipt of written notice, the employee's dosimeter record shall be reviewed immediately and necessary steps shall be taken to meet the dose limit specified in table 1 of Rule 205.

(2) For determining the doses specified in Rules 203 to 215, a dose from x- or gamma rays up to 10 MeV may be assumed to be equivalent to the exposure measured by a properly calibrated appropriate instrument in air at or near the body surface of the region of the highest exposure rate.

(3) A licensee or registrant may permit an individual in a restricted area to receive a dose to the whole body greater than that permitted in subrule (1) of this rule, under any of the following conditions:

Page 40 Courtesy of www.michigan.gov/orr

(a) The annual dose does not exceed 5 rems in any 1 year and during any calendar quarter the dose to the whole body from sources of radiation in the licensee's or registrant's possession does not exceed 3 rems.

(b) The dose to the whole body, when added to the accumulated occupational dose to the whole body, does not exceed 5 (N-18) rems where "N" equals the individual's age in years at his or her last birthday.

(c) The licensee or registrant has determined the individual's accumulated occupational dose to the whole body on Form RH-101, or on a clear and legible record containing all the information required in that form and has otherwise complied with the requirements of Rule 206.

(4) Upon application showing an operational need, the department may authorize radiation doses at a higher annual level than the limits set forth in subrule (1) of this rule, provided that the dose does not exceed 3 rems per quarter and that, based on the determination of the individual's prior radiation record, his or her accumulated occupational dose does not exceed 5 (N-18) rems where "N" equals the individual's age in years at his or her last birthday.

(5) As used in this part, "dose to the whole body" includes any dose to the whole body, gonads, active blood-forming organs, head and trunk, or lens of the eye.

(6) Nothing in this part shall be interpreted as limiting the exposure of members of emergency response teams to radiation under emergency circumstances for the purpose of minimizing danger to life or property. Teams may include police, fire, ambulance, and paramedical crews acting in the course of their assigned duties.

(2) Before permitting an individual in a restricted area to be exposed to radiation in excess of the limits specified in table 1 of Rule 205, each licensee or registrant shall do all of the following:

(a) Obtain a certificate on Form RH-101, or on a clear and legible record containing all the information required in that form, signed by the individual, showing each period of time after the individual attained the age of 18 in which the individual received an occupational dose of radiation.

(b) Calculate on Form RH-101, in accordance with the instructions appearing therein, or on a clear and legible record containing all the information required in that form, the previously accumulated occupational dose received by the individual and the additional dose allowed for the individual under Rule 203 (3) or (4).

(3) In the preparation of Form RH-101, or on a clear and legible record containing all the information required in that form, the licensee or registrant shall make a reasonable effort to obtain reports of the individual's previously accumulated occupational dose. For each period for which the licensee or registrant obtains these reports, he or she shall use the dose shown in the report in preparing the form. Where a licensee or registrant is unable to obtain reports of the individual's occupational dose for a previous complete calendar quarter, it is assumed that the individual has received the occupational dose specified in whichever of the following columns apply:

R 325.5270 Notes to Appendices A1 to A9. Rule 270. *Soluble (S): Insoluble (I). **"Sub" means that values given are for submersion in a semi-spherical infinite cloud of airborne material. ***For purposes of these rules, it may be assumed that the daughter activity concentrations in the following table are equivalent to an air concentration of 10-7 microcuries of radon-222 per milliliter of air in equilibrium with the daughters polonium-218, lead-214, bismuth-214, and polonium-214:

Maximum Time Between Alpha-Emitting Daughter Activity Collection Collected per Milliliter of Air

and Measurement Microcuries Total Alpha Disintegrations (hours)*† per milliliter per minute per milliliter

0.5 7.2 x 10-8 0.16 1.0 4.5 x 10-8 0.10 2.0 1.3 x 10-8 0.028 3.0 0.3 x 10-8 0.0072

*†The duration of sample collection and the duration of measurement should be sufficiently short compared to the time between collection and measurement, as not to have a statistically significant effect upon the results. ****For soluble mixtures of U-238, U-234, and U-235 in air, chemical toxicity may be the limiting factor. If the percent by weight (enrichment) of U-235 is less than 5, the concentration value for a 40-hour workweek, table I, is 0.2 milligrams uranium per cubic meter of air average. For any enrichment, the product of the average concentration and time of exposure during a 40- hour workweek shall not exceed 8 x 10-3 SA µCi-hr/ml, where SA is the specific activity of the uranium inhaled. The concentration value for table II is 0.007 milligrams uranium per cubic meter of air. The specific activity for natural uranium is 6.77 x 10-7 curies per gram U. The specific activity for other mixtures of U-238, U-235, and U-234, if not known, shall be:

SA = 3.6 x 10-7 curies/gram U U-depleted SA = (0.4 + 0.38 E + 0.0034 E2) 10-6 E> 0.72 where E is the percentage by weight of U-235, expressed as percent.

NOTE: In any case where there is a mixture in air or water of more than 1 radionuclide, the limiting values for purposes of this appendix should be determined as follows: 1. If the identity and concentration of each radionuclide in the mixture are known, the limiting values should be derived as follows: Determine, for each radionuclide in the mixture, the ratio between the quantity present in the mixture and the limit otherwise established in Appendix “A” for the specific radionuclide when not in a mixture. The sum of such ratios for all the radionuclides in the mixture may not exceed “1” (i.e., “unity”). Example: If radionuclides a, b, and c are present in concentrations Ca, Cb, and Cc, and if the applicable Maximum Permissible Concentrations (MPC's) are MPCa, MPCb, and MPCc respectively, then the concentrations shall be limited so that the following relationship exists:

Ca Cb Cc MPC +a MPC +b MPC < 1c

2. If either the identity or the concentration of any radionuclide in the mixture is not known, the limiting values for purposes of Appendix "A" shall be: a. For purposes of Table I, Column 1 6 x 10-13 b. For purposes of Table I, Column 2 4 x 10-7 c. For purposes of Table II, Column 1 2 x 10-14 d. For purposes of Table II, Column 2 3 x 10-8 3. If any of the conditions specified hereinafter are met, the corresponding values specified there may be used in lieu of those specified in Paragraph 2 above. a. If the identity of each radionuclide in the mixture is known but the concentration of one or more of the radionuclides in the mixture is not known, the concentration limit for the mixture is the limit specified in Appendix “A” for the radionuclide in the mixture having the lowest concentration limit; or, b. If the identity of each radionuclide in the mixture is not known, but it is known that certain radionuclides specified in Appendix “A” are not present in the mixture, the concentration limit for the mixture is the lowest concentration limit specified in Appendix “A” for any radionuclide that is not known to be absent from the mixture; or

NOTES TO APPENDIX C It should be emphasized that because of the wide range of physical factors, no one value (of

the few which can be incorporated in a standard) can relate health effects to contamination levels in all the diverse situations in which contamination is measured. Accordingly, standards for contamination levels must be used as guides (or decision levels). The above levels shall therefore be applied with the following guidance:

1. The levels are to be used as guides, and in practice professional judgment should be used

by the health physicist to determine the acceptability of the actual contamination.

2. Although it is felt that the recommended values should not result in a health hazard, good radiation protection practice dictates that a reasonable effort be made to keep actual contamination levels below these values.

3. Compliance with contamination guides shall not be used as evidence that exposing

persons to internal or external sources of radiation is within the prescribed standards. Biological sampling or whole body counting should be used to ascertain internal doses.

4. For release of material to the general public:

a. A reasonable effort shall be made to minimize the contamination (i.e. the application of additional decontamination procedures have little effect on the contamination levels).

Page 81 Courtesy of www.michigan.gov/orr

b. Surfaces of premises or equipment likely to be contaminated that are inaccessible for measurement shall be presumed to be contaminated in excess of the above limits and not released.

5. The levels adopted are for generally used isotopes of high toxicity, therefore lower levels

may be appropriate for extremely toxic radionuclides and relaxations allowed for less toxic radionuclides.
