In larger amounts, Cs-137 is used in medical radiation therapy devices for treating cancer; in industrial gauges that detect the flow of liquid through pipes; and in other industrial devices to measure the thickness of materials, such as paper, photographic film, or sheets of metal.


Caesium-137 has been employed in a variety of industrial measurement gauges, including moisture, density, levelling, and thickness gauges. It has also been used in well logging devices for measuring the electron density of the rock formations, which is analogous to the bulk density of the formations.

Halter av cesium-137 (Cs-137) i vildsvinskött är höga jämfört med andra viltslag. Studier i Europa, där vildsvin hela tiden har funnits i områden drabbade av Tjernobylolyckan, visar att cesiumhalterna sjunker mycket långsamt och att problemen med vildsvin är mer långvariga än för till exempel rådjur och älg. 1986-04-26 Cesium-137 and its decay product, barium-137m, are used for sterilization activities for food products, including wheat, spices, flour, and potatoes. Cesium-137 is also used in a wide variety of industrial instruments such as level and thickness gauges and moisture density gauges.

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. 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. Caesium-137 (137 55Cs), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons.

137 Cs voidaan käyttää myös syöpien hoidossa: onttoon neulaan laitetaan cesiumia, joka ruiskutetaan potilaaseen. Säteily tuhoaa syöpäsolukkoa ja voi auttaa taudin parantamisessa. 137 Cs käytetään myös eroosion tutkimiseen: cesiumia laitetaan maaperään, ja myöhemmin tutkitaan kuinka pitkälle radioaktiivinen cesium on liikkunut maaperässä.

Caesium-137 has been found to effect children in the same way as adults. Similar to adults, stable caesium, Cs-133, is not likely to have an affect on children's health; however, just like with any radionuclide, exposure to large amounts of radioactive caesium-137 will induce large amounts of gamma radiation that will damage vital cells and could culminate in random DNA indels and the manifestation of cancerous cells.
