测定了赤道东太平洋深海岩心所表达的间隙水中Ra、Th和U的同位素浓度。同位素226Ra、228Ra、230Th和228Th的浓度比它们在海水中的浓度高1 ~ 3个数量级。表明了镭从沉积相释放并向水柱迁移。结果也与深海自生矿物中发现的过量228Th（相对于232Th）相一致。
The Ra, Th, and U isotopic concentrations were determined in the interstitial water expressed from a deep sea core of the eastern equatorial Pacific. The isotopes 226Ra, 228Ra, 230Th, and 228Th are higher by 1 to 3 orders of magnitude than their concentrations in seawater. Radium release from sedimentary phases with migration into the water column is indicated. The results are also compatible with the excess 228Th (relative to 232Th) found in authigenic deep sea minerals.
