HAR §11-45-48. Dose limits for individual members of the public

(a) Each licensee shall conduct operations so that: (1) The total effective dose equivalent to individual members of the public from the licensed operation does not exceed 0.1 rem (one millisieverts) in a year, exclusive of the dose contribution from the licensee's disposal of radioactive material into sanitary sewerage in accordance with section 11-45-72 (Retrofit shall not be required for locations within facilities where only radiation machines existed before the effective date of these rules and met the previous requirements of 0.5 rem (five millisieverts) in a year), and (2) The dose in any unrestricted area from external sources does not exceed 0.002 rem (0.02 millisieverts) in any one hour. (b) If the licensee allows members of the public to have access to controlled areas, the limits for members of the public continue to apply to those individuals. (c) A licensee may apply for prior department authorization to operate up to an annual dose limit for an individual member of the public of 0.5 rem (five millisieverts). This application shall include the following information: (1) Demonstration of the need for and the expected duration of operations in excess of the limit in subsection (a); and (2) The licensee's program to assess and control dose within the 0.5 rem (five millisieverts) annual limit; and (3) The procedures to be followed to maintain the dose ALARA. (d) In addition to the requirements of subchapter 4, a licensee subject to the provisions of the U.S. Environmental Protection Agency's generally applicable environmental radiation standards in 40 C.F.R. Part 190 shall comply with those standards. (e) The department may impose additional restrictions on radiation levels in unrestricted areas and on the total quantity of radionuclides that a licensee may release in effluents in order to restrict the collective dose.

(a) The licensee shall make or cause to be made surveys of radiation levels in unrestricted and controlled areas and radioactive materials in effluents released to unrestricted and controlled areas to demonstrate compliance with the dose limits for individual members of the public in section 11-45-48. (b) A licensee shall show compliance with the annual dose limit in section 11-45-48 by: §11-45-49 45-58 (1) Demonstrating by measurement or calculation that the total effective dose equivalent to the individual likely to receive the highest dose from the licensed operation does not exceed the annual dose limit; or (2) Demonstrating that: (A) The annual average concentrations of radioactive material released in gaseous and liquid effluents at the boundary of the unrestricted area do not exceed the values specified in Table II of Appendix B; and (B) If an individual were continually present in an unrestricted area, the dose from external sources would not exceed 0.002 rem (0.02 millisieverts) in an hour and 0.05 rem (0.50 millisieverts) in a year. (c) Upon approval from the department, the licensee may adjust the effluent concentration values in Appendix B, Table II, for members of the public, to take into account the actual physical and chemical characteristics of the effluents, such as, aerosol size distribution, solubility, density, radioactive decay equilibrium, and chemical form.
