Cesium-137, stejně jako ostatní izotopy cesia, reaguje s vodou za vzniku rozpustného hydroxidu cesného. Cesium má podobné biologické vlastnosti jako draslík a rubidium. Jakmile se dostane do organismu, tak se více či méně distribuuje po celém těle, přičemž nejvyšší koncentrace jsou v měkkých tkáních.

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. 2019-10-24 2016-06-30 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.

2016-06-30 · Radioactive cesium—specifically, cesium-137—is one of the waste products of nuclear power. It’s also one of the most dangerous substances in a nuclear disaster like Chernobyl or Fukushima.

2000-04-01 Caesium is one of those elements that feels unfamiliar, caesium chloride extracted from the mineral. But to create the radioactive form of the compound, it is enriched with caesium isotopes, particularly caesium-137, produced in nuclear reactor waste. A dangerous glow. Generally, Cesium-137, iodine-131, strontium-90, and plutonium are the principal radioisotopes of concern during the crisis at the Fukushima 1 Nuclear Power Plant in Japan, as a result of reactor explosions, fires, and releases of radioactive steam following the 8.9 Richter scale earthquake and tsunami on 11 March, 2011. Radioisotope Brief: Cesium-137 (Cs Cesium-137 (137 Cs) on cesiumin radioaktiivinen isotooppi, joka muodostuu yleisimmin ytimen halkeamis- eli fissioreaktiossa.. Cesium-137:n puoliintumisaika on noin 30 vuotta. Suurin osa isotoopista cesium-137 hajoaa beetahajoamisella barium-137:ksi, joka on stabiili ydin.
