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.
