Question 8: Under what circumstances are planned special

exposures permitted?

Answer: The statement of considerations indicates that the

intent of the planned special exposure was that it be used

infrequently in circumstances where the elimination of the

5 (N-18) lifetime cumulative limit might create a severe

handicap to the licensee's operation. See Regulatory Guide

8.N6, for further detailed guidance. (Reference: 10 CFR

20.1206)
