本文报道了海洋中镭~(228)的首次测量结果,并讨论了测定镭~(228)和钍~(228)的分析方法。相对于Th 232,海洋中存在可测量的过量Ra 228和Th 228。Ra 228应该被证明是研究水运动的有价值的示踪剂。其6.7年的半衰期使其适用于3-25年时间范围的工艺。
The first measurements of radium 228 in the ocean are reported, and the analytical methods of determining Ra228 and Th228 are discussed. Measurable excesses of both Ra228 and Th228 relative to the Th232 exist in the ocean. Ra228 should prove a valuable tracer for studies of water movements. Its 6.7-year half-life makes it applicable to processes with a time scale of 3–25 years.
