12VAC5-481-730: Compliance with dose limits for individual members of the public

A. The licensee shall make or cause to be made, as appropriate, 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 12VAC5-481-720.

B. A licensee shall show compliance with the annual dose limits in 12VAC5-481-720 by:

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 2 of Appendix B to 10 CFR Part 20; and

b. If an individual were continuously present in an unrestricted area, the dose from external sources would not exceed 2 millirem (0.02 mSv) in an hour and 50 millirem (0.5 mSv) in a year.

C. Upon approval from the agency, the licensee may adjust the effluent concentration values in Table 2 of Appendix B to 10 CFR Part 20, for members of the public, to take into account the actual physical and chemical characteristics of the effluents (e.g., aerosol size distribution, solubility, density, radioactive decay equilibrium, and chemical form).
