Health Physics Questions and Answers - Question 29
Question 29: If a licensee controls exposure to members of the public using the new Part 20.1302 (b) (2) at the boundary of the unrestricted area, how does a licensee ensure that members of the public inside the controlled area do not exceed this limit?
Answer: Principally by the control of access and, thereby, exposure time, since the licensee can require members of the public to exit the controlled area at any time. (10 CFR 20.1301 (b) provides that if a licensee permits members of the public to have access to controlled areas, the limits for members of the public continue to apply to those individuals.)
