Eight lactating dairy cows were each given 1 mc of Cs/sup 134/ and 6 mc of K/sup 42/ in a single oral dose. An average of 6.7% of the Cs/sup 134/ and 4.2% of the K/sup 42/ was secreted into milk in 66 hr. Corresponding values for urinary excretion were 19.0 and 38.0%. Averages of 10.5, 30.0, and 32.7% of the cesium/sup 134/ were found in milk, urine, and feces, respectively, in 210 hr. The variation in Cs/sup 134/ and K/sup 42/ secreted into milk can largely be explained on the basis of differing milk yields, with concentration remaining somewhat constant. The concentration of Cs/sup 134/ and K/sup 42/ in urine and the volume of urine are both highly variable. (Public Health Eng. abstr., 61: No. 6, 1961)
