Radiation Dose Limits: Compliance with Dose Limits for Individual Members of the Public


(1)

The licensee or registrant must 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 OAR 333-120-0180 (Radiation Dose Limits: Dose Limits for Individual Members of the Public).

(2)

A licensee or registrant must show compliance with the annual dose limit in OAR 333-120-0180 (Radiation Dose Limits: Dose Limits for Individual Members of the Public) by:

(a)

Demonstrating by measurement or calculation that the total effective dose equivalent to the individual likely to receive the highest dose from the licensed or registered operation does not exceed the annual dose limit; or

(b)

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 10 CFR Part 20 Table 2 of Appendix B to 20.1001 to 20.2401; and

(B)

If an individual were continually present in an unrestricted area, the dose from external sources would not exceed 0.02 mSv (0.002 rem) in an hour and 0.5 mSv (0.05 rem) in a year.

(3)

Upon approval from the Authority, the licensee or registrant may adjust the effluent concentration values in 10 CFR Part 20 Table 2 of Appendix B to 20.1001 to 20.2401 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, chemical form).
