FOOTNOTES

to

SCHEDULE OF RADIOACTIVE MATERIAL LICENSE FEES

1

Amendments based on applications filed after the due date of the annual license fee reducing

the scope of a licensee's program or cancelling a license, will not entitle the licensee to a partial

refund of an annual fee that has been paid by the licensee for the year in which such amendment

or cancellation occurs. Applications for amendments increasing the scope of a program to a

higher fee category will not be accepted for filing unless accompanied by the prescribed fee less

the amount of the currently prescribed fee for the activities already licensed.

Page 27

2

3

Applications for specific licenses covering more than 1 fee category shall be accompanied by

the prescribed fee for each category.

Payment of the prescribed annual fee does not automatically renew the license for which the fee

is paid. Renewal applications shall be filed in accordance with the requirements of Rule 120.

Applications for reissuance of licenses that have expired because a timely renewal application

was not filed shall be accompanied by the prescribed application fee.

4

The annual fee will be waived where an application is filed to cancel the license prior to the due

date of the annual fee, and the amount of the annual fee will be reduced where an application is

filed to amend the license to reduce its scope before the due date of the annual fee. However, an

annual fee will not be waived or reduced unless the application filed before the due date of the

fee contains all the information necessary to permit the department to complete the requested

action

History: 1979 AACS; 2016 AACS.

R 325.5145 Payment of fees.

Rule 145. (1) License fee payments shall be by check, draft, or money order payable to the "State

of Michigan".

(2) In any case where the department finds that a licensee has failed to pay the applicable annual

fee required in this part, the department may suspend or revoke the license or may issue such order

with respect to licensed activities as the department determines to carry out these rules and the act.

NOTE 1: Many radionuclides disintegrate into nuclides which are also radioactive. In

expressing the concentrations in Schedule A the activity stated is that of the parent nuclide and

takes into account the daughters.

NOTE 2: For purposes of Rule 65 where there is involved a combination of nuclides, the limit

for the combination should be derived as follows: Determine for each nuclide in the product the

ratio between the concentration present in the product and the exempt concentration established

in Schedule A for the specific nuclide when not in combination. The sum of such ratios may not

exceed "1" (i.e., unity).

EXAMPLE:

Concentration of Nuclide A in Product

Exempt concentration of Nuclide A

Concentration of Nuclide B in Product

Exempt concentration of Nuclide B

PART 5. STANDARDS FOR PROTECTION AGAINST RADIATION

R 325.5201 Purpose and scope.

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:

(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.

R 325.5206 Determination of accumulated dose.

Rule 206. (1) This rule applies to licensees or registrants who propose, pursuant to Rule 203 (3)

or (4), to permit individuals in a restricted area to receive radiation doses in excess of the limits

specified in table 1 of Rule 205.

(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:

(4) The licensee or registrant shall retain and preserve records used in preparing Form RH-101. If

calculation of the individual's accumulated occupational dose for all periods before January 1,

1961 yields a result higher than the applicable accumulated dose value for the individual as of that

date, as specified in Rule 205, the excess may be disregarded.

History: 1979 AACS; 2016 AACS.

R 325.5208 Exposure of individuals to radioactive material in restricted areas.

Rule 208. (1) A licensee shall not receive, acquire, possess, use, or transfer radioactive material in

such a manner as to cause an individual in a restricted area to be exposed to airborne radioactive

material in an average concentration in excess of the limits specified in table I of appendix A in Rules

261 to 270. "Expose," as used in this rule, means that the individual is present in a region where an

airborne concentration exist. An allowance shall not be made for the use of protective clothing or

equipment, or particle size, except as authorized by the department pursuant to subrule (3) or (4) of

this rule.

(2) The limits given in table I of appendix A in Rules 261 to 270, are based upon an individual

being exposed to the specified concentrations for the reference period of 40 hours in any 7

consecutive days. In any such period where an individual has been exposed for less than the 40

hours, the limits specified may be increased proportionately. In any such period where an

individual has been exposed for more than 40 hours, the limits specified in the table shall be

decreased proportionately.

(3) The department may authorize a licensee to expose an individual in a restricted area to

airborne concentrations in excess of the limits specified in table I of appendix A in Rules 261 to

270, upon receipt of an application demonstrating that the concentration is composed in whole or

in part of particles of such size that the particles are not respirable and that the individual will not

inhale the concentrations in excess of the limits established in the table. An application submitted

pursuant to this subrule shall include an analysis of particle sizes in the concentrations and

description of the methods used in determining the particle sizes.

(4) The department may authorize a licensee to expose an individual in a restricted area to

airborne concentrations in excess of the limits specified in table I of appendix A in Rules 261 to

270, upon receipt of an application demonstrating that the individual will wear appropriate

protective equipment and that the individual will not inhale, ingest, or absorb quantities of

radioactive material in excess of those which might otherwise be permitted under this part for

individuals in restricted areas during a 40-hour week. An application submitted pursuant to this

subrule shall contain all of the following information:

(a) A description of the protective equipment to be employed, including the efficiency of the

equipment for the material involved.

(b) Procedures for the fitting, maintenance, and cleaning of the protective equipment.

(c) Procedures governing the use of the protective equipment, including supervisory procedures

and length of the time the equipment will be used by the individuals in each work week. The

Page 42

proposed periods for use of the equipment by any individual should not be of such duration as

would discourage observance by the individual of the proposed procedures.

(d) The average concentrations present in the areas occupied by individuals.

(e) Procedures for bio-assay evaluation of the effectiveness of the proposed protective safeguards.

History: 1979 AACS; 2016 AACS.

R 325.5209 Orders requiring furnishing of bio-assay services.

Rule 209. Where necessary or desirable in order to aid in determining the extent to which an

individual was or may be exposed to concentrations of radioactive material, the department may

incorporate license provisions or issue an order requiring a licensee or registrant to make available

to the individual appropriate bio-assay services and to furnish a copy of the reports of such services

to the department.

History: 1979 AACS.

R 325.5210 Exposure of minors.

Rule 210. (1) A licensee or registrant shall not receive, acquire, possess, use, or transfer sources

of radiation in a manner as to cause an individual who is under 18 years of age, to receive in any

period of 1 calendar quarter from all sources of radiation in the licensee's or registrant's possession,

a dose in excess of 10% of the quarterly occupational limit specified in Rule 205 (e.g. 125 mrems

whole body).

(2) A licensee shall not receive, acquire, possess, use, or transfer radioactive material in such a

manner as to cause any individual in a restricted area, who is under 18 years of age, to be exposed

to airborne radioactive material in an average concentration in excess of the limits specified in

table II of appendix A in Rules 261 to 270. For purposes of this subrule, concentrations may be

averaged over periods not greater than 1 week (7 consecutive days).

(3) Rule 208 (1) shall apply where an individual is exposed subject to subrule (2) of this rule.

History: 1979 AC; 2016 AACS.

R 325.5211 Radiation levels from external sources in unrestricted areas.

Rule 211. (1) Except as authorized by the department pursuant to subrule (2) of this rule, a

licensee or registrant shall not receive, acquire, possess, use, or transfer sources of radiation in

such a manner as to result in an individual in an unrestricted area receiving a dose in excess of the

following:

(a) Two millirems in any 1 hour.

(b) One hundred millirems in any 7 consecutive days.

(c) Five hundred millirems in any 1 year.

(2) A person may apply to the department for proposed limits upon levels of radiation in

unrestricted areas in excess of those specified in subrule (1) of this rule resulting from the

applicants possession or use of sources of radiation. The application shall include information as

Page 43

to anticipated average radiation levels and anticipated occupancy times for each unrestricted area

involved. The department shall approve the proposed limits if the applicant demonstrates to the

satisfaction of the department that the proposed limits are not likely to cause any individual to

receive a dose to the whole body in any period of 1 calendar year in excess of 0.5 rem.

History: 1979 AC; 2016 AACS.

R 325.5212 Concentrations in effluents to unrestricted areas.

Rule 212. (1) A licensee shall not receive, acquire, possess, use, or transfer licensed material so as

to release to an unrestricted area radioactive material in concentrations that exceed the limits

specified in table II of appendix A in Rules 261 to 270, except as authorized pursuant to subrule (2)

of this rule or Rule 238. For purposes of this rule, concentrations may be averaged over a period not

greater than 1 year.

(2) An application for a license or amendment may include proposed limits higher than those

specified in subrule (1) of this rule. The department shall approve the proposed limits if the applicant

demonstrates both of the following:

(a) The applicant has made a reasonable effort to minimize the radioactivity contained in effluents

to unrestricted areas.

(b) It is not likely that radioactive material discharged in the effluent would result in the exposure

of an individual to concentrations of radioactive material in air or water exceeding the limits

specified in table II of appendix A in Rules 261 to 270.

(3) An application for higher limits pursuant to subrule (2) of this rule shall include information

demonstrating that the applicant has made a reasonable effort to minimize the radioactivity

discharged in effluents to unrestricted areas, and shall include, as pertinent, the following:

(a) Information as to flow rates, total volume of effluent, peak concentration of each radionuclide

in the effluent, and concentration of each radionuclide in the effluent averaged over a period of 1

year at the point where the effluent leaves a stack, tube, pipe, or similar conduit.

(b) A description of the properties of the effluents, including the following:

(i) Chemical composition.

(ii) Physical characteristics, including suspended solids content in liquid effluents, and nature of

gas or aerosol for air effluents.

(iii) The hydrogen ion concentrations (pH) of liquid effluents.

(iv) The size range of particulates in effluents released into air.

(c) A description of the anticipated human occupancy in the unrestricted areas where the highest

concentration of radioactive material from the effluent is expected, and, in the case of a river or

stream, a description of water uses downstream from the point of release of the effluent.

(d) Information as to the highest concentration of each radionuclide in an unrestricted area,

including anticipated concentrations averaged over a period of 1 year in the following:

(i) In air at any point of human occupancy.

(ii) In water at points of use downstream from the point of release of the effluent.

(e) The background concentration of radionuclides in the receiving river or stream before the release

of liquid effluent.

Page 44

(f) A description of the environmental monitoring equipment, including sensitivity of the system,

and procedures and calculations to determine concentration of radionuclides in the unrestricted area

and possible reconcentrating of radionuclides.

(g) A description of the waste treatment facilities and procedures used to reduce the concentration

of radionuclides in effluents before their release.

(4) For the purposes of this rule, the concentration limits in table II of appendix A in Rules 261 to

270 apply at the boundary of the restricted area. The concentration of radioactive material discharged

through a stack, pipe, or similar conduit may be determined with respect to the point where the

material leaves the conduit. If the conduit discharges within the restricted area, the concentration at

the boundary may be determined by applying appropriate factors for dilution, dispersion, or decay

between the point of discharge and the boundary.

(5) In addition to limiting concentrations in effluent streams, the department may limit quantities

of radioactive materials released in air or water during a specified period of time if it appears that the

daily intake of radioactive material from air, water, and food by a suitable sample of an exposed

population group, averaged over a period not exceeding 1 year, would otherwise exceed the daily

intake resulting from continuous exposure to air or water containing 1/3 the concentration of

radioactive materials specified in table II of appendix A in Rules 261 to 270.

(6) This rule does not apply to disposal of radioactive material into sanitary sewerage systems,

which is governed by Rule 239.

PRECAUTIONARY PROCEDURES

R 325.5221 Surveys.

Rule 221. (1) As used in this rule, "survey" means a critical evaluation of a facility or area incident

to the production, use, release, disposal, or presence of sources of radiation under a specific set of

conditions to determine actual or potential radiation hazards. When appropriate, the evaluation

includes tests, physical examination, source inventory and accountability, and measurements of

levels of radiation or concentration of radioactive material present.

(2) Each licensee or registrant shall make or cause to be made surveys as may be necessary to

establish compliance with these rules.

History: 1979 AC; 2016 AACS.

R 325.5222 Personnel monitoring.

Rule 222. (1) Each licensee or registrant shall supply appropriate personnel monitoring

equipment to, shall require the use of such equipment by, and shall demonstrate compliance

pursuant to this rule for the following:

(a) Each individual under such circumstances that he or she receives, or is likely to receive, a

dose in any calendar quarter in excess of 25% of the quarterly occupational limit specified in Rule

205, (e.g. 300 mrems whole body).

(b) Each individual under 18 years of age under such circumstances that he or she receives, or is

likely to receive, a dose in any calendar quarter in excess of 5% of the quarterly occupational limit

specified in Rule 205, (e.g. 60 mrems whole body).

(c) Each individual, except a patient being intentionally irradiated, who enters a high radiation

area.

(d) Each individual who is likely to receive a dose in excess of 100 millirems in any 5 consecutive

days while in a room or area occupied by a patient while the patient is receiving therapy from any

gamma-emitting radioactive material.

(e) Each individual for whom personnel monitoring is specifically required under other parts of

these rules pertaining to specific uses of sources of radiation.

(2) Monitoring devices used to estimate whole body exposure shall normally be worn on the chest

or abdomen. The dosimeter assigned for monitoring the trunk of the body shall not be used for any

other purposes. If monitoring of other areas of the body (e.g. lens of the eye, extremity) is required

by these rules or requested by the radiation worker because of the nature of exposure, a separate

dosimeter shall be assigned for this purpose. The separate dosimeter shall be designated as an

auxiliary dosimeter and the radiation record shall specify the specific area monitored.

(3) If auxiliary dosimeters are assigned in accordance with subrule (2) of this rule, the specific

body area shall be monitored for a minimum 13 consecutive weeks. If this monitoring results in

recorded exposures in excess of 25% of the applicable specified quarterly limit in Rule 205 (e.g.

Page 50

300 mrems lens of the eye, 6.25 rems hands), the auxiliary dosimeter shall be permanently assigned

to monitor that area.

*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^-7microcuries of radon-222 per

milliliter of air in equilibrium with the daughters polonium-218, lead-214, bismuth-214, and

polonium-214:

*^†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^-3SA 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^-7curies 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^-7curies/gram U U-depleted

SA = (0.4 + 0.38 E + 0.0034 E²) 10^-6E> 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 C_a, C_b, and C_c, and if the

applicable Maximum Permissible Concentrations (MPC's) are MPC_a, MPC_b,and MPC_c

respectively, then the concentrations shall be limited so that the following relationship exists:

C_a

MPC_a

C_b

MPC_b

C_c

MPC_c

+

< 1

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

Page 73

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.

Page 80

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).

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.
