Cesium-137 is a very common fission product. Nuclear fission is used in nuclear power plants. The heat produced by nuclear fission can be converted into electricity. 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.

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

It is commonly used as a gamma-emitter in industrial applications such as moisture and density gauges, Regulators have ignored warnings that the licensing of devices containing radioactive cesium-137 should stop, and hundreds remain in use, an L.A. Times investigation has found. Caesium-137 Poisoning. Caesium-137 has a half-life of about 30 years. However, as it is highly water soluble, in actual uses cesium-137 ions are easily accumulated in the body, where their biological half-life is 110 days. Chemical Structure.

Cesium 137 uses

Cesium-137 is used in atomic clocks, the most precise method for measuring time. A beam of energy is shined on a very pure sample of cesium-133. The atoms in the cesium are excited by the energy and give off radiation. That radiation vibrates back and forth, the way a violin string vibrates when plucked.

Although Cs-137 decays via beta – decay, it is the daughter nuclide’s subsequent gamma emissions that are responsible for most dose when used as an enclosed source in cancer treatment. Cesium (Cs) is a metal with atomic number 55, group 1, and period 6. It can be non-radioactive or radioactive. Cesium-137 is one of its most common radioactive forms.

Radiometric or gamma level/density instruments are most often used in Typical industrial isotopes used in radiometric applications are cesium-137 (Cs-137)

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. Known year-to-year variation within that period allows correlation with soil and sediment The Cesium 137 Test .

The most common commercial source of cesium is pollucite, which contains between .

In industry, radioactive cesium is also used in instruments that measure thickness, moisture, and liquid flow. Let us know look at some more information and facts about Cesium. Cesium has 11 main radioactive isotopes. Out of the above mentioned isotopes, the main ones of concern are cesium-134, cesium-135 and cesium 137. Cesium is present naturally in the soil and also as isotope 133.

Also Caesium-137 is used in the medical industry for radiation therapy devices for treating cancer. 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
