A survey was made of levels of strontium-89 and strontium-90 from fallout in samples of soil, vegetation, and animal bone collected from selected pasture sites in North Carolina, New York, Georgia, Utah, and New Jersey during 1953 and 1954. The bone levels showed an average increase by a factor of 2.4. Data are presented graphically showing the relationship of the calcium content in the soil to strontium-90 uptake in animal bones. The ratio of strontium-90 to strontium-89 in the uptake cycle at each site was determined. The fallout at each site during the animal grazing period and the vegetation growth period was collected on gummed paper exposed for weekly intervals at each site. Data are tabulated. The vegetation collected at the end of the growth period showed a strontium-90 to strontium-89 ratio similar to the fallout material for the period. This was considered evidence of leaf retention.
