Section 340
Section 340.320 Compliance
with Dose Limits for Individual Members of the Public
a) The licensee or registrant shall make or cause to be made
surveys of radiation levels in unrestricted areas. In addition, licensees
shall survey radioactive materials in effluents released to unrestricted
areas. These surveys are to demonstrate compliance with the dose limits for
individual members of the public in Section 340.310.
b) A licensee or registrant shall show compliance with the annual
dose limit in Section 340.310 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 or registered 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 20, published
at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or
editions; and
B) If an individual were continuously 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.
c) Upon approval from the Agency, the licensee may adjust the
effluent concentration values in table 2 of appendix B to 10 CFR 20, published
at 72 Fed. Reg. 55922, October 1, 2007, exclusive of subsequent amendments or
editions, 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).
