The data from over 80 thyroids collected during 1973, 1974, and 1975 from animals residing on the Nevada Test Site indicate that iodine-129 levels in these thyroids are near background levels. However, the median levels in the thyroids of animals living on the Nevada Test Site are slightly elevated from those found in northern Nevada, but are similar to those found near Denver, Colorado, and Rawlins, Wyoming. Statistical analyses of the iodine-129/iodine-127 ratios in cattle thyroids suggest that three populations were sampled. These populations are: (1) northern Nevada cattle which were considered as a baseline population, (2) corralled Nevada Test Site cattle with intermediate ratios, and (3) free-grazing cattle from Nevada Test Site and Rocky Flats, Colorado, which had the highest ratios reported.
