Facts About Prussian Blue | CDC
Prussian blue reduces the biological half-life of cesium from about 110 days to about 30 days. The biological half-life is the amount of time it takes for the radioactive material to leave the body, which decreases its harm. Prussian blue reduces the biological half-life of thallium from about 8 days to about 3 days. Back to Top.

The cesium actually is made up of four isotopes: cesium-133 (stable), cesium-134 (2- year half-life), cesium-135 (2.3 million years), and cesium-137. Cesium-134 is produced in very small concentrations, which are reduced further by decay. Cesium-137 constitutes about 25 to 32 percent of the cesium atoms.

The chemical nature and properties of soil contaminants
The main radionuclides of concern at polluted sites are strontium-90, cesium-137 and plutonium-239 with half-lives of 29 000, 30 000 and 24 000 years, respectively. Radiostrontium and radiocesium are readily taken up by plants, animals and humans due to their similarity to calcium and potassium, and are hence more toxic.
