摘要：

Previous workers have reported Th232 concentrations in surface sea water ranging from 0.3 to 0.6 μg/1000 1. Whereas these estimates were based on the analysis of single samples, the present work is based on a composite of 24 analyses of water collected from widely spaced parts of the ocean. A careful interpretation of the alpha spectrometer data indicates that the true concentration is less than 0.07 μg Th232 1000 1. © 1969.
