Current through Register Vol. 47, No. 6, September 18, 2024
(1) The licensee or registrant 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 40.26(136C).
(2) A licensee or registrant shall show compliance with the annual dose limit in 40.26(136C) 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:
(1) 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
(2) If
an individual were continually present in an unrestricted area, the dose from
external sources would not exceed 0.002 rem (0.02 mSv) in an hour and 0.05 rem
(0.5 mSv) in a year.
(3) Upon
approval from the agency, the licensee or registrant 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.
