Licensees and registrants must control doses to individual members of the public as follows.

013.01 DOSE LIMITS. Each licensee or registrant must conduct operations so that:

(A) The total effective dose equivalent to individual members of the public from the licensed or registered operation does not exceed 1 mSv ( 0.1 rem) in a year, exclusive of the dose contributions from background radiation, from any medical administration the individual has received, from exposure to individuals administered radioactive material and released in accordance with 180 NAC 7-037, from voluntary participation in medical research programs, and from the licensee's or registrant's disposal of radioactive material into sanitary sewerage in accordance with 180 NAC 4-04; and

(B) The dose in any unrestricted area from external sources, exclusive of the dose contributions from patients administered radioactive material and released in accordance with 180 NAC 7-037, does not exceed 0.02 mSv ( 0.002 rem) in any one hour.

013.02 MEMBERS OF THE PUBLIC IN RESTRICTED AREAS. If the licensee or registrant permits members of the public to have access to restricted areas, the limits for members of the public continue to apply to those individuals.

013.03 VISITORS. Despite the requirements of 180 NAC 4-013.01(A), a licensee may permit visitors to an individual who cannot be released, under 180 NAC 7-037, to receive a radiation dose greater than 1 mSv ( 0.1 rem) if:

(A) The radiation dose received does not exceed 5 mSv ( 0.5 rem); and

(B) The authorized user, as defined in 180 NAC 7, has determined before the visit that it is appropriate.

013.04 PRIOR AUTHORIZATION. A licensee, registrant, or an applicant for a license or registration may apply for prior Department authorization to operate up to an annual dose limit for an individual member of the public of 5 mSv ( 0.5 rem). This application must include the following information:

(A) Demonstration of the need for and the expected duration of operations in excess of the limit in 180 NAC 4-013.01; and

(B) The licensee's or registrant's program to assess and control dose within the 5 mSv ( 0.5 rem) annual limit; and

(C) The procedures to be followed to maintain the dose as low as reasonably achievable (ALARA).

013.05 ADDITIONAL REQUIREMENTS. In addition to the requirements of 180 NAC 4, a licensee or registrant subject to the provisions of the U.S. Environmental Protection Agency's generally applicable environmental radiation standards in 40 CFR 190 must comply with those standards.

013.06 ADDITIONAL RESTRICTIONS. In order to restrict the collective dose, licensees and registrants may be required to further restrict radiation levels in unrestricted areas or on the total quantity of radionuclides that may be released in effluents.
