ea ete meee conducted a survey of Runit Island in May 1972. Both beta-gamma survey meters and Fiddler meters (for plutonium detection, by means of \ . os . , americum-2‘1 content) were used, the former for beta- and gamma-ray detection and the latter for plutonium detection. on 10-foot grids. 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. Urine samples of full-time workers in the area never showed alpha-particle activities larger than a very small fraction of tolerance (Kinsey, 1973). Asa consequence of z these findings, the precautionary quarantine on Runit was lifted on without anv corrective actions needed for the island. cee ret Seman te enemyeanewe | ? — ew nme pee i mea aromer ces _ of alpha particle activity and 24 =e caren we ’ ; Soil samples were taken for plutonium analysis in laboratories in the U.S. in the dust. s Measurements were made
