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.) (Reference: 10 CFR 20.1302)
