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.

Strontium-90 concentrations have been determined in a variety of foods used by the native population. Caribou from the tundra carry 10 to 20 times the level of domestic cattle. Eskimos for whom caribou is a staple in the diet are found to have four times the strontium-90 content of the average for the world population of the North Temperate Zone.
