This document summarizes and responds to several sources that discuss issues related to radiation monitoring and sample analysis at Rocky Flats: 1) It notes that EPA interviews found samples were sometimes allowed to sit for weeks before analysis, which could compromise results. However, NIOSH responded that for the target radionuclides, delays of weeks would not impact results due to their long half-lives. 2) The NCRP recommends prompt analysis of biological samples to avoid deterioration, and refrigeration, acidification or preservatives if samples must be kept over a day. 3) Several sources discuss differences, weaknesses and non-compliance in radiation monitoring practices and equipment calibration at Rocky Flats.
