Cesium-137 is useful in medical and industrial radiology because of its long half-life of 30.17 years. However, as a major component of nuclear fallout and a waste product left over from the production of plutonium and other enriched nuclear fuels, it presents an environmental hazard.

Everyone is exposed to very small amounts of cesium-137 in soil and water as a result of atmospheric fallout. Exposure to waste materials, from contaminated sites, or from nuclear accidents can result in cancer risks Cesium has a low tendency to adsorb to particles in water, and discharges of 137 Cs from the Windscale Piles could be traced in seawater in the Irish Sea, the north of Scotland, and along the Norwegian coast around Svalbard, not reaching “background concentrations” (originating from global fallout from nuclear weapons testing) until the current, after 6-8 years and 5000-7000 km, reached 137 Cs from radioactive waste involve solvent extraction using macrocyclic polyethers, or crown ethers and coprecipitation with sodium tetraphenylboron (Burt 1993). One of the most interesting uses of cesium is in the production of highly accurate atomic clocks. When 2014-11-24 Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. 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.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles. Caesium 137 is also one of the principal sources of radioactive contamination after nuclear reactor accidents. After Chernobyl, for instance, large quantities of caesium were released into the atmosphere, but by 1995 the levels of radiation had dropped below what they had been before the 1986 accident.

Caesium in 'high PH therapy' is supposably meant to reduce the acidity level in tumour cells, but there is no scientific research to prove that it actually works. Conventionally Caesium is used to penetrate cancer cells and kill them, but there The most common radioisotope of cesium is cesium-137.

Uses/Sources: Cesium-137 is produced from the detonation of nuclear weapons and is produced in nuclear power plants. Cesium-137 was released to the atmosphere most notably from the 1986 Chernobyl meltdown. It is commonly used as a gamma-emitter in industrial applications such as moisture and density gauges,

Cesium is present naturally in the soil and also as isotope 133. Non-radioactive cesium is also used to treat depression. Healthcare providers sometimes treat cancer patients with radioactive cesium (cesium-137). In industry, radioactive cesium is also used in instruments that measure thickness, moisture, and liquid flow. One of its most important uses is in the ‘caesium clock’ (atomic clock). These clocks are a vital part of the internetand mobile phone networks, as well as Global Positioning System (GPS) satellites.

While this process is going on, cesium-137 is being produced as a by-product. That cesium-137 can be collected and used for a number of applications. Caesium-137 has been used in hydrologic studies analogous to those with tritium. As a daughter product of fission bomb testing from the 1950s through the mid-1980s, caesium-137 was released into the atmosphere, where it was absorbed readily into solution.

Cesium-137 is also commonly used in hospitals for diagnosis The suggestion to use caesium-137 (137Cs) as a tracer for soil erosion assessment originated in the 1960s when environmental scientists investigated land contamination by radionuclides released during nuclear weapons tests.
