Cesium-137 is a radioactive isotope which is produced in fission reactions. It emits beta particles to decay into barium-137. The half-life for this decay  Half Life Cesium-137. Logga inellerRegistrera.

About 94.6% decays by beta emission to a metastable nuclear isomer of barium: barium-137m (137m Ba, Ba-137m). The remainder directly populates the ground state of barium-137, which is stable. Cesium-137 has a radioactive half-life of about 30 years and decays by beta decay either to stable barium-137 or a meta-stable form of barium (barium -137m).

Cesium 137 half life

1981). The half-life of cesium-137 is 30 years. Suppose we have a 100-mg sample. 9.

A half-life is the time it takes for a substance to reduce to half its initial size. Being a radioactive substance, Cesium-137 emits beta and gamma rays.

Videos you watch may be added to the TV's watch history and influence TV 2018-04-04 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. In 1987, civilians in Goiania, Brazil, were accidentally exposed to caesium-137. Cesium-137 undergoes high-energy beta decay, primarily to an excited nuclear isomer of Barium 137, which in turn undergoes gamma decay with a half-life of about 150 seconds.

Halveringstid – Wikipedia

Half-life: 30.17 years. Mode of decay: Beta and gamma radiation. Chemical properties: Liquid at room temperature, but readily bonds with chlorides to form a powder. More than twenty years after the Chernobyl accident, attention focuses mainly on one particular radioactive nucleus : caesium-137. Iodine-131, dreadful in the weeks following the disaster, has disappeared because of its 8 days radioactive half-life (or period).
