Science, 1957
The world-wide average strontium-90 content of man was about 0.12 micromicrocurie per gram of calcium (1/10,000 of the maximum permissible concentration) in the fall of 1955. A few values as high as 10 times the average have been obtained. This value is in accord with the predicted value based on fallout measurements and fractionation through

Science, 1963
The hair of rats injected with strontium-90 retains a significant amount of the radionuclide. Although the strontium-90 content of hair is variable in these rats and appears to be subject to a variety of influences, determination of the radionuclide content of hair may offer a nondestructive method of estimating strontium-90 in bone.

II. Uptake and Retention of Strontium 90 in Strontium-90-Induced Osteosarcomas
Acta Radiologica, 1962BS>Osteosarcomas developed after 6 or 7 months in 200 CBA-strain male mice that received an injection of Sr/sup 90/. An autoradiographic study was made in order to investigate the distribution in tumors and unchanged bone-tissue of the radiostrontium that was injected. The sections used for autoradiography were also examined by microradiography.

Strontium-90 Metabolism during Low Strontium-90 Intake in Man
Radiation Research, 1964Balance studies of Sr90 have been previously performed in this laboratory under controlled dietary conditions in normal young adults (1). In these studies, the Sr90 intake was relatively high, since the diet was supplemented with milk. Tlle high fecal excretion of Sr90 indicated that the major portion of the ingested Sr90 passed unabsorbed through the ...

Samples of bone and soil collected in 1958 show highest values for Sr 90 in the tropical region on the east side of the Andes. Lowest values are found in the high central valley, where samples used in estimating world-wide distribution of fallout were collected. If the major fallout deposition occurs in the interior

Strontium-90 and Infant Mortality
Nature, 1969The recent claim that strontium-90 resulting from tests of nuclear weapons has killed 400,000 children in the United States since 1945 does not stand up to careful analysis.

Strontium 90 effective half-life is 2.7 x 10/sup 3/ days. It emits beta rays and is selectively absorbed by bone. Strontium-90 is chemically allied to calcium and it moves with this element through the food chains and the foods which supply calcium to the body also supply strontium.
