Health Physics Questions and Answers - Question 21

Question 21: Is it time to update Regulatory Guide 1.109 and its corresponding codes due to the updated dose conversion factors in the revised Part 20?

Answer: Perhaps, but such an update could only be a partial update at this time. The full updating could only occur if and when Appendix I is recast as an effective dose equivalent. The evaluation of whether Appendix I should be changed is currently underway.
