| Popis: | The mobility of plutonium was measured by laboratory experiments conducted under conditions simulating the groundwater environment. The results thus obtained are discussed in comparison with those obtained with an in situ study on fallout plutonium migration. Plutonium (IV) was found in a series of laboratory experiments to have large distribution coefficients ( K d ). On the other hand, the K d values of the fallout plutonium were about one-tenth as large as those of Pu (IV). This might be ascribed to either the different oxidation states or the difference in the chemical forms. Furthermore, a trace amount of mobile plutonium was confirmed to be produced even in the simulated groundwater environment. The production rate of mobile plutonium and the degree of change in chemical forms of plutonium during underground migration were found to be strongly influenced by the amount of suspended solids in the groundwater. |
