Welford, G.A. comp.

A survey was made of levels of strontium-89 and strontium-90 from fall- out 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 san 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 ln animal bones. The ratio of strontium-90 to strontium89 in the uptake cycle at each site was determined. The fall-out at each site during the animal grazing peried 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 strontiuin-90 to strontium-89 ratio similar to the fall-out material for the period. This was considered evidence of leaf retention.
