Wolff, A H

Iodine-131 activity was readily found in thyroid glands from grazing animals in Arizona, Pennsylvania, Ohio, and Oregon within 2 weeks following the start of the 1956 US Pacific atomic weapons tests. A progressive increase was noted in the proportion of samples which were active from mid-May to mid-October, at which time the study was terminated. Based on the Arizona and Ohio data, the average weekly dosages from mid-May to mid-October to cattle and sheep were 35 and 120 milli-roentgen equivalent physical, respectively, apparently harmless to the health of animals. It is suggested that the average cattle /sup 131/I level found in this study is approximately the average continuously existing in US cattle during the past 2 or 3 years. Theoretical considerations indicate that with the levels of /sup 131/I found in cattle thyroids, detectable amounts of /sup 131/I would have been secreted with the fresh milk produced in these areas.
