Health Physics Questions and Answers - Question 51

Question 51: Do 10 CFR 20.2104 (a), 10 CFR 20.2104 (d) and Footnote 4 to 20.2104 (d) mean that a licensee must "backfit" effective dose equivalents (EDE) for individuals who were occupationally exposed before implementation of the revised Part 20?

Answer: No. Such backfitting is not required. However, licensees may, if they so desire, make estimates of the EDE and committed EDE based on the occupational dose records available for this period.
