conducted a survey of Runit Island in May 1972. Both beta-gamma survey meters and Fiddler meters (for pluconium detection, by means of americm-241 content) were used, the former for beta- and gamna-ray detection and the latter for plutonium detection, on 10-foot exids. Soil samples were taken for plutonium analysis in laboratories in the U.S. Air samplers were used to test for plutonium Generally, these air samplers showed no detectable activity, but did record as high as 0.24 d/min-meter 28.4 d/min-meter of beta-gamma activity. RR IRER Re Sen em ae in the dust. Measurements were made of alpha particle activity and Urine samples of full-time workers in the area never showed alpha-particle activities larger than a very small fraction of tolerance (Kinsey, 1973). As a consequence of these findings, the precautionary quarantine on Runit was lifted on without any corrective actions needed for the island. 24 (g) ? a
