Concentrations of I(131) in the thyroids of deer from Washington, Colorado, and Maryland, and of caribou from Alaska were measured after the resumption of nuclear weapon tests by the U.S.S.R. on 1 September 161. Maximum concentrations occurred nearly 2 months after the first nuclear test and then decreased at an effective half-time of about 15 days. Thyroids from Washington and Colorado deer showed the highest concentrations, thyroids from Alaskan caribou the lowest.
在苏联于1961年9月16日恢复核武器试验之后，对来自华盛顿州、科罗拉多州和马里兰州的鹿以及来自阿拉斯加的北美驯鹿甲状腺中的碘-131浓度进行了测量。最高浓度出现在首次核试验后近2个月，然后以约15天的有效半衰期下降。华盛顿州和科罗拉多州鹿的甲状腺浓度最高，阿拉斯加北美驯鹿的甲状腺浓度最低。
