Cesium-137 | Cs - PubChem

Cesium-137 is produced in nuclear fission and occurs in atmospheric debris from weapons tests and accidents. It is a very important component of radioactive fallout; and because of its moderately long half-life and high solubility, it is a major source of long-lived external gamma radiation from fallout.

Caesium-137 - Wikipedia

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium which 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.

Radionuclide Basics: Cesium-137 | Radiation Protection | US EPA

Because Cs-137 bonds with chlorides to make a crystalline powder, it reacts in the environment like table salt (sodium chloride): 1. Cesium moves easily through the air. 2. Cesium dissolves easily in water. 3. Cesium binds strongly to soil and concrete, but does not travel very far below the surface. 4. Plants and vegetation growing in or nearby contaminated soil may take up small amounts of Cs-137 from the soil.Small quantities of Cs-137 can be found in the environment from nuclear weapons a...

Hazardous isotopes: Cesium-137, Iodine-131, Strontium-90

Cesium-137 arises as a cleavage product in the nuclear fission of uranium. Cesium-137 reacts further as a β- source to give barium-137. The barium-137 is generated in an excited state (what is referred to as “metastable”), but becomes stable after release of γ-radiation.Cesium-137 has a half-life of 30 years; for example, if 1000 cesium-137 atoms are present, then 500 of these will be transformed into barium-137 over a 30-year period. Of the remaining 500 cesium-137 atoms, 250 will be similar...

Radioisotope Brief: Cesium 137 (Cs 137)

External exposure to large amounts of Cs-137 can cause burns, acute radiation sickness, and even death. Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation. Internal exposure to Cs-137, through ingestion or inhalation, allows the radioactive material to be distributed in the soft tissues, especially

1.10: Uses of Radioactive Isotopes - Chemistry LibreTexts

Cesium-137 is a radioactive isotope that has a half-life of 30.1 y. It was introduced into the atmosphere in the 1940s and 1950s by the atmospheric testing of nuclear weapons by several countries after World War II. A significant amount of cesium-137 was released during the Chernobyl nuclear disaster in 1986.

Caesium-137 - an overview | ScienceDirect Topics

The most common radioisotope of cesium is cesium-137. It emits beta and gamma radiation, decaying to stable barium-137. Cesium-137 is widely used in gamma sources. It occurs in these sources as cesium chloride pellets. Cesium chloride is a soluble salt. The contamination from a sealed-source leak absorbs water, becomes damp, and creeps.

cesium 137 | Heal Fukushima

While we generally worry about radioactive iodine concentrating in the thyroid, Bandazhevsky’s work shows us that Cesium-137 is likely to play a major role in thyroid cancer too. If Cesium-137 enters the body, it is distributed fairly uniformly throughout the body’s soft tissues, resulting in exposure of those tissues.
