| 内容記述 | Concentrations of rhenium, a chemical analogue of Tc, were measured in various environmental samples by ICP-MS to obtain informational values on long-lived 99Tc mobility in the environment. From the results, it was assumed that Re was removed from the rock and soil by water due to weathering and transported to the sea through rivers. The element would be retained in seawater for a long time, i.e., 2x105 to 7.5x105 y. The reservoirs of Re in the sea would be seaweeds, and anoxic and suboxic sediments, especially slightly below the water-sediment interface. | |||||
