Due to a lapse in appropriations, the NRC has ceased normal operations. However, excepted and exempted activities necessary to maintain critical health and safety functions—as well as essential progress on designated critical activities, including those specified in Executive Order 14300—will continue, consistent with the OMB-Approved NRC Lapse Plan.

Health Physics Questions and Answers - Question 19

Question 19: Current computer codes, such as LADTAP and GASPAR, calculate individual organ doses for comparison against individual organ dose limits in 10 CFR 50 Appendix I and/or Technical Specifications. Will the codes have to be modified to convert whole body and organ doses to effective dose equivalents?

Answer: Appendix I is not changed by the revised Part 20. Therefore, until Appendix I is changed, licensees must continue to show compliance with technical specifications based on Appendix I and expressed in terms of organ and whole body doses.
