Health Physics Questions and Answers - Question 8
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.
