Cesium-137 Uses · Its strong radioactive nature makes it very useful as isotopes in nuclear weapons, nuclear reactors, and industries. · It is used as a moisture- 

VI. Applications the 662 kev gamma of barium-137m is used materialp, reflection and density. Radiometric or gamma level/density instruments are most often used in Typical industrial isotopes used in radiometric applications are cesium-137 (Cs-137)  Cesium-137 is a radioactive element with a half-life of thirty years. This experiment uses a glass isogenerator and a 9.0 pH specific chemical solution called  In this exercise, the gamma spectrum from a Cs-137 source is studied. This is also an A so-called scintillation detector is used.

Cesium Facts, Symbol, Discovery, Properties, Uses chemistrylearner.com What is Cesium Used For in Everyday Life? | Study.com study.com Caesium: a metal used to check clocks - … terrorist use of radioactive materials 13 Jacob Kamen, Ph. D., CHP Hospitals and research centers around the United States—and around the world--are addressing security, safety and liability con- cerns by replacing blood irradiators that use cesium-137 with FDA-approved x-ray tech- … Caesium-137 has a number of practical uses.

Both Cs 137 and its metastable nuclear isomer, barium -137m, emit gamma radiation of moderate energy and so are used in sterilization procedures in the food industry or in hospital environments.

As such, there is not much cesium-137 in the environment today. It is possible for cesium-137 to still be released into the environment via nuclear reactors (used to create energy). However, this Non-radioactive cesium is also used to treat depression. Healthcare providers sometimes treat cancer patients with radioactive cesium (cesium-137).
