was 13.05 mg/g dry weight with a standard deviation of 3.66. No significant correlation between cesium-137 and potassium levels was found. There wse no significant difference in the average levels of cesium-137 in crabs collected at different times at the same island.

Primary Report No.: UWFL-29 Journal Announcement: NSA14 Availability: NTIS Document Type: Report Language: English Contract No.: AT(45-1)-540 The values for strontium-90 and gross beta activity in the fat and non-fat fractions from the livers of twelve coconut crabs (Birgus latro) collected at Rongelap Atoll during March 1958 are presented. Although fat constituted an average of 47 percent by weight on a wet weight basis (74 percent on a dry weight basis), gross beta activity of the fat fraction amounted to less than 0.5 percent of the total activity on a wet weight basis. Fat content on a wet percent. weight basis had a range of 31 percent to 65 There is a linear relationship between strontium-90 activity and gross beta activity. Since the fat content of coconut crab liver is variable and the fat fraction contains practically no radioactivity, it is suggested that the radioactivity (and mineral content) of liver samples be compared on the basis of the non-fat solids.

Language: English ~ Radiochemical analyses were made of contaminated marine organisms collected from the Pacific Ocean between 1954 and 1958. The presence of zirconium~-65, iron-55. iron-59, cobalt-57, cobalt-58, cobalt-60, cadmium-113, and other nuclides was confirmed. Data are tabulated. Results are related to nuclear weapons tests in the Bikini region.
