Primary Report Na.: UWFL-64 Journal Anncuncement: NSA14 Availability: NTIS Document Type: Report Language: English Contract Now: AT(45-1)-540 Radiccesium and stable petassium levels were determined in samples caf muscle tissue cf Birgus latro, the coconut crab, collected at Rengelap Atoll], Marshall Islands, during March and August 1958 and March 1959, and at Utirik Atoll in March 1959. Levels af cesium-137 ranged between 731 d/m/g dry weight at Kabelle Island, Rengelap Atcl!, and 28 d/m/q dry weight at Utirik Island, Utirik Atoll. The average potassium value for all samples was 13.05 mg/g dry weight with a standard deviation of 3.66. No significant cerrelation between cesium-137 and potassium levels was found. There wse ro significant difference in the average levels af cesium-137 in crabs collected at different times at the same island.
