Strontium-90 on the Earth's Surface
Nature, 1968Estimations of the amount of strontium-90 on the Earth's surface indicate that maximum fallout occurred late in 1966. Of the 13 MCi recorded at the beginning of 1967, 82 per cent of this was in the northern hemisphere.

The determination of 90Sr by ICP-MS is capable of providing a high sample throughput compared with radiometric analytical methods. Although the isobaric interference caused by 90Zr ions can be reduced by reaction with oxygen, the high background caused ...

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

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 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.

PURPOSE To report three cases of canine corneal squamous cell carcinoma (SCC) treated with strontium 90 beta radiation as an adjunct to surgical excision. METHODS Corneal SCC was excised with lamellar keratectomy. This was followed by local application

S>A single injection of strontium-90 was administered to groups of female mice at 2 dose levels. Survival and the causes of death were studied. The results in shortening of the lifespan and in frequency of bone tumor parallel data previously reported. Analyses of the causes of death showed that in experimental and control mice more than 80% died with ...
