(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.
