United States Nuclear Regulatory Commission - Protecting People and the Environment

U.S. Nuclear Regulatory Commission

Question 135: 10 CFR 20.1206 permits a planned special

exposure (PSE) only if the alternatives that might avoid

the higher exposure are unavailable or impractical. Under

certain conditions, the collective dose for a task could be

reduced if it could be performed by one worker receiving a

PSE, rather than by a series of several workers each

receiving a dose less than the limit. Under these

conditions would the NRC consider the alternative of using

the series of workers to be unavailable or impractical?

Answer: No. Reductions in collective dose should be

accomplished while keeping workers within the dose limits.

Planned special exposures cannot be justified solely on the

basis that they will reduce collective dose; however,

reduction in collective dose may be part of the

justification. (Reference: 10 CFR 20.1206).
