Question 104: 10 CFR 20.1302 provides two options for

demonstrating compliance with the annual dose limit, in 10

CFR 20.1301, for members of the public. How does 10 CFR

20.1302 (b) (2), the second option, provide demonstration

of compliance with the annual dose limit for members of the

public who are in a controlled area?

Answer: It doesn't. This second option applies to

members of the public in unrestricted areas and a

controlled area is not an unrestricted area. However, it

would be acceptable to demonstrate compliance with the

annual dose limit for members of the public in a controlled

area [10 CFR 20.1301 (a) and (b)] by applying the effluent

concentration criteria of 10 CFR 20.1302 (b) (2) (i) and

the external dose criterion of 10 CFR 20.1302 (b) (2) (ii)

to the controlled area, rather than to the unrestricted

area. (References: 10 CFR 20.1003, 10 CFR 20.1302).
