It is of interest that the highest milk drinker (not plotted) who drank glasses of milk per day, had only 64 uwuc cst 37 gram K. 12 We postulate that heavy milk drinkers get less Potassium and Cesium from other (non-milk) sources, than do low milk drinkers. Hence, the correlation between total body Cesium and milk consumption is only moderate. The average Cesium to Potassium ratio measured in adults living in Sait Lake City is 67 wuc cs 3 gram K. Anderson?) has reported an average value of 44 wuc cs!3? ygram Potassium for persons in the United States. Mitter(6) reports an average value of 34 uuc cs }3? rgram K for 13 persons from the Chicago area, 32 uuc Cs 137 pgram K for 5 Europeans, and 14.6 wuc 537 ¢gram K for 11 persons from Central and South America. It is apparent that the average Cesium value measured in people living in Salt greater than the average of the rest of the United Lake City, States. Utah, is The Strontium concentrations of 34.6 uc sro gram Ca in the soil in Salt Lake City is about double the average Strontium concentration of United states ‘?), 14.7 wuc sr? gram Ca for the The proximity of Salt Lake City to the Nevada atomic bomb test area may be responsible for the higher concentrations of these fallout radioelements. Accuracy of Measurement To evaluate the statistical accuracy of our measurements, three subjects (D.H.T., B.W.G., and C.W.M.) were each measured six times and their computed values of Potassium and Cesium are as follows:
