Abstract : Plutohium, uranium, americium, and gamma spectrometric analyses were performed on over two thousand Operation Roller Coaster physical and biological samples. Separate laboratory facilities were maintained for the biological and physical samples to prevent cross-contamination of the activities of the two sample types. In general, samples of low activity were analyzed first, and samples of approximately equal activities were analyzed in groups to further minimize cross-contamination. A quality control program involving the analyses of standards, splits, and blanks demonstrated the precision of the plutonium analysis to be 4.4 percent at the 95-percent confidence level with no trend in the precision with time and no significant contribution to the determined sample activities from laboratory contamination.
