Strontium-90 in Alaska.

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.

Uptake of strontium-85 by alfalfa.

Experiments with alfalfa were carried out to study the possibility of changes with time in the availability of radiostrontium in soil. After the soil was treated once with Sr85, the first crop was harvested after 60 days of growth. Four subsequent crops, cut at successive 4-week intervals, were examined. The difference in uptake between the second and fifth crops was statistically significant, suggesting that some fixation of Sr85 may occur in the soil. The effects of various applications of ammonium dihydrogen phosphate, monocalcium phosphate, calcium chloride, and potassium chloride on the uptake of Sr85 by alfalfa were also investigated. Of the experiments carried out, only the treatment with 1.0 meq of potassium per 100g of soil resulted in a statistically significant reduction in strontium uptake.

RADIOACTIVITY MEASUREMENTS IN ALASKAN ESKIMOS IN 1963.

During the summer of 1963 people at five villages above the Arctic Circle in Alaska were measured for accumulated radioactivity with a portable whole-body counter. Adults of the interior village of Anaktuvuk Pass showed the highest average body burden, 628 nanocuries of cesium-137. This is an increase of nearly 50 percent over the summer before. The maximum burden foundwas 1.24 microcuries.

RADIOACTIVITY MEASURED IN ALASKAN NATIVES, 1962-1964.

Measurements of the cesium-137 content of northern Alaskan natives during the summer of 1964 indicated that the adults of the interior village of Anaktuvuk Pass had the highest average body burden: 1280 nanocuries of cesium-137. This is an increase of 200 percent over the average body burden found in the summer of 1962 and 100 percent over that found in the summer of 1963. The greatest burden found in a native in 1964 was 2.4 microcuries of cesium-137, but the highest burden of all, 3.0 microcuries, was measured in a non-native living mainly on caribou meat. Sodium-22 was found in samples of urine from Eskimos, and subsequently in the Eskimos themselves and in reindeer and caribou meat.
