Question 207: The dose limits for an individual member of
the public as specified in 10 CFR 20.1301 are specified in
terms of rem. Since rem is an absorbed dose, must an
individual be present for the dose limit to apply?
Answer: No. If using 10 CFR 20.1302 (b) (1) to show
compliance with dose limits, occupancy times (time an
individual is present) may be taken into account. If using
the method in 10 CFR 20.1302 (b) (2) (ii) to demonstrate
compliance, dose is calculated as if an individual were
continuously present, regardless of whether an individual
is continuously present. See related Questions 68, Set 2,
and 102 Set 3. (Reference: 10 CFR 20.1302, 10 CFR 20.1301)
