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.

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. (auth)

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.
