Radioactive cesium has been considered one of the more hazardous radioactive nuclides produced in nuclear fission. Upon ingestion, like potassium, cesium distributes itself throughout the soft tissue and has a relatively short residence time in the body. Half-lives of 134Cs and 137Cs are 2 and 30 years, respectively, both being beta- and gamma-emitters.
