Cesium137: RadioChemistry, Fate, and Transport ...

In recent years, considerable interest has arisen with regard to the fate and transport of radionuclides such as iodine131 (131I), cesium134 (134Cs), and cesium137 (137Cs) in aquatic environments. 137Cs is an important indicator of radioactive pollution in aquatic environments. The transport and fate of anthropogenic 137Cs is related to the ...

Furthermore, the longlived cesium is a critical indicator of radioactive contamination in aquatic environments. Cesium in the environment derives from a variety of sources. The prime single source was result from atmospheric nuclear weapons tests in the 1950s and 1960s, which had dispersed and accumulated cesium worldwide [7]. For treatment of soils contaminated with radionuclides, different ...

A Zeolite ionexchange process was developed and used on the Hanford Atomic Energy Project for the separation of radioactive cesium from highly radioactive liquid wastes (Mercer and Ames 1976). The waste had developed high cesium content from filtering liquid waste and a system was developed to backexchange the cesium for reuse.

We examined aqueous cleaning as a remediation method for rice straw contaminated with radioactive isotopes. Aqueous cleaning decreased the radioactivity of cesium contaminated rice straw by twothirds. Nearly all of the radioactivity removed from the straw was attached to residual particles filtered from the wash water, which exhibited very low levels of radioactivity. This shows that aqueous ...
