SECTION 310:281-9-12. Personnel monitoring

(a)   Each permittee shall supply appropriate personnel monitoring equipment to, and shall require the use of such equipment by:

(1)   each individual who enters a radiation area;

(2)   each individual who enters a high radiation area; and

(3)   each individual who uses or operates any source of radiation.

(b)   The Department may, upon written request from a permittee grant an exemption to 310:281-9-12(a) provided, in the opinion of the Department upon consideration of information submitted in support of such a request, that no individual is likely to receive a dose in any calendar year in excess of 25 percent of the applicable value specified in 310:281-9-2 and that no individual under 18 years of age is likely to receive a dose in any calendar year in excess of 5 percent of the applicable value specified in 310:281-9-2.

(c)   After the effective date of these rules, all personnel monitoring equipment (except extremity dosimeters and pocket ionization chambers) that require processing to yield a dose value and that are provided to comply with 310:281-9-2 and 310:281-9-12(a), or the applicable terms and conditions of any license or certificate of registration issued by the Department shall:

(1)   be processed by a processor accredited by the National Voluntary Laboratory Accreditation Program for Personnel Dosimetry Processors of the National Bureau of Standards in accordance with accreditation criteria established in 15 CFR Part 7b; and

(2)   be approved in this accreditation process for the type of radiation or radiations and the time period for which the individual wearing the dosimeter is monitored.

(d)   Location and use of individual monitoring equipment.

(1)   each permittee shall ensure that individuals who are required to monitor occupational doses in accordance with 310:281-9-12(a) wear and use individual monitoring equipment as follows:

(A)   Individual monitoring equipment shall be assigned to and worn by only one individual.

(B)   Individual monitoring equipment used for monitoring the dose to the whole body shall be worn at the unshielded location of the whole body likely to receive the highest exposure. When a protective apron is worn, the location of the individual monitoring equipment is typically at the neck (collar).

(C)   If additional individual monitoring equipment is used for monitoring the dose to an embryo/fetus of a declared pregnant woman, in accordance with 310:281-9-40, it shall be located at the waist under any protective apron being worn by the woman.

(D)   Individual monitoring equipment used for monitoring LDE, to demonstrate compliance with 310:281-9-2(a), shall be located at the neck (collar) or at a location closer to the eye, outside any protective apron being worn by the monitored individual.

(E)   Individual monitoring equipment used for monitoring the dose to the extremities, to demonstrate compliance with 310:281-9-2(a), shall be worn on the extremity likely to receive the highest exposure. Each individual monitoring equipment, to the extent practicable, shall be oriented to measure the highest dose to the extremity being monitored.

(F)   Individual monitoring equipment shall be worn for the period of time authorized by the dosimetry processor's certificate of registration or for no longer than three months, whichever is more restrictive.
