Current through Vol. 24-12, July 15, 2024
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 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.
