SUMMARY
The discussion centers on determining the appropriate values of weighting factors (WT) for internal radiation dose calculations, specifically for neutron exposure and the ingestion of isotopes 90Sr and 131I. The consensus indicates that for neutron whole-body doses, WT should be set to 1. However, for ingested isotopes, the correct WT values are debated, with suggestions of WT = 0.12 for the stomach and WT = 0.04 for the thyroid. Clarification is needed on whether to apply these specific WT values based on the organ affected by ingestion.
