Compound: Tritium (H-3) Emergency Signs DISPOSAL Radioactive Equipment That reminds me of a terrible radioactive accident that happened in Brazil in the 80s' when a decommissioned radiotherapy machine ended up in a regular scrapyard. The owner of the scrapyard disassembled the core containing radioactive caesium chloride (a salt of cesium-137) and was captivated by the blue glow of the substance. Due to the long half-life of caesium-137 (30 years), the environment of these regions were subjected to contamination, even to this day. A 1972 Brazilian case study on the carcinogenicity of caesium-137 examined the health effects in humans exposed to caesium-137.
Trace quantities also originate from natural fission of uranium-238.

Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium. Cesium-137 is therefore a common radionuclide produced when nuclear fission, or splitting, of uranium and plutonium occurs in a reactor or atomic bomb. What are the uses of cesium-137? Cesium-137 and its decay product, barium-137m, are used for sterilization activities for food products, including wheat, spices, flour, and potatoes. 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. The energies of both the beta decay of cesium-137 and the subsequent gamma decay of the excited barium 137 are 512 keV and 662 keV, respectively.
Cesium má podobné biologické vlastnosti jako draslík a rubidium. Jakmile se dostane do organismu, tak se více či méně distribuuje po celém těle, přičemž nejvyšší koncentrace jsou v měkkých tkáních.

Cesium-137, iodine-131, strontium-90, and plutonium are the principal radioisotopes of concern during the crisis at the Fukushima 1 Nuclear Power Plant in Japan, as a result of reactor explosions, fires, and releases of radioactive steam following the 8.9 Richter scale earthquake and tsunami on 11 March, 2011. Radioisotope Brief: Cesium-137 (Cs In the radiation head, a container of radioactive cesium-137, 2 inches wide and 1.8 inches long, was housed in lead. The patient would lie on a table underneath the machine, exposing whatever cancer-stricken body part necessary. Once everyone was settled and safe, the aperture would be opened, firing its beam.
