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 ...

Strontium-90 and Skeletal Formation
Science, 1957The potential radiostrontium level to be expected in the skeletons of growing children as a result of environmental contamination was computed. Results are based on available data on the rate of bone remodeling and exchange, the rate of skeletal growth, and the level of /sup 90/Sr in the biosphere.

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.

Science, 1960
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

IN 1963, Hopkins et al.1 reported the accumulation of significant amounts of strontium-90 in the hair of rats which had acquired known body burdens of the radio-nuclide either by injection or in utero. They further suggested that the analysis of hair could provide a non-destructive method of measuring bone seeking radio-elements.

Strontium 90 fallout prediction
Deep Sea Research Part B. Oceanographic Literature Review, 1986An empirical formula is developed for predicting monthly sea level strontium 90 fallout (F) in the northern hemisphere as a function of time (t), precipitation rate (P), latitude (ϕ), longitude (λ), and the sea level concentration of strontium 90 in air (C): F(λ, ϕ, t) = C(t, ϕ)[νd(ϕ) + νw(λ, ϕ, t)], where νw(λ, ϕ, t) = a(ϕ)[P(λ, ϕ, t)/P0]b(ϕ) is the ...

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.

Measurements were made of the Sr/sup 90/ content of 121 teeth collected in 1959. After a number of analytical steps, the final Sr/sup 90/ content was determined by counting carrier-free Y/sup 90/ daughter. A statistical analysis of results indicates that there is a definite inverse correlation between Sr/sup 90/ concentration and age.

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.
