| Abstract: | The concentrations of89Sr,90Sr,210Pb and210Po were measured in a series of rain samples collected at Fayetteville (36°N, 94°W), Arkansas, after the 14th Chinese test
of March 18, 1972, which occurred at Lop Nor (40°N, 90°E), China. Approximately concordant tropospheric residence times were
obtained from the89Sr/90Sr and210Po/210Pb ratios in rain. The89Sr/90Sr ratios were also measured for the rain samples collected at Tokyo (36°N, 140°E), Japan, and at Ankara (40°N, 33°E), Turkey. |
