Cleaning up Chernobyl with Sunflowers – Athens Science Observer
In a process called phytoremediation, hyperaccumulating plants are used to clean up environmental contamination. Well, it just so happens that sunflowers are particularly adept at extracting radioactive metals, like the cesium-137 and strontium-90 found at Chernobyl. After the Chernobyl disaster fields of sunflowers were planted to …

Radionuclide Basics: Cesium-137 | US EPA
Radionuclide Basics: Cesium-137. Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137. Cesium-137 is produced by nuclear. for use in medical devices and gauges.

Effective washing removal of radioactive cesium from soils using
Conventional washing methods release little radioactive cesium fixed in soils. Adding a Cs+ adsorbent to a suspension of Cs-contaminated soil rapidly removes the Cs+ released to the solution, causing more Cs+ release from the soil. We investigated this method by adding a sheet embedded with mordenite powder to a suspension of 133Cs+ …

Remediation of plants contaminated with cesium by aqueous cleaning
Aqueous cleaning removed two-thirds of the radioactivity from cesium-contaminated plants. Instead of being transferred to the water, cesium was attached to particles of rice straw. These particles were analyzed by micro-PIXE to determine the surface distribution of several elements. The elemental ratio of cesium to silicon was …
