The Chernobyl disaster is now 30 years behind us, and during those years the radioactivity attributable to caesium-137 has decayed to half of its original level. Caesium-137 is a troublesome fission product because caesium’s most common chemical compounds are salts, which can move easily through natural environments.

In the 1960s, an average Cs biological half-time of 86 days was reported for 23 Japanese male adults under quasi-equilibrium conditions in regard to cesium-137 from atmospheric Cesium-137 is therefore a common radionuclide produced when nuclear fission, or splitting, of uranium and plutonium occurs in a reactor or atomic bomb. What are the uses of cesium-137? Cesium-137 and its decay product, barium-137m, are used for sterilization activities for food products, including wheat, spices, flour, and potatoes. 137 Cs is taken up into organisms through the same routes as potassium, and the ability of cells to transport potassium against concentration gradients to obtain high intercellular concentrations also leads to a fairly high bioconcentration of radioactive cesium. After the Chernobyl accident in 1986, a considerable amount of 137 Cs was The radioactive substance cesium-137 takes many years to break down with an estimated half-life of 30 years.

The Fukushima reactor, however, has so far released 360,000 TBq of cesium-137, according to TEPCO. In 2005, IRSN produced a simulation of the path travelled across Europe by the radioactive cloud folowing the Chernobyl accident. This simulation was produced using a new generation of operational atmospheric dispersion models developed for use in case of nuclear emergency. To qualify this new long-distance dispersion model, IRSN experts applied it to the atmospheric release of caesium-137 Césium 137. 143 likes.

Due to the long half-life of caesium-137 (30 years), the environment of these regions were subjected to contamination, even to this day. Context: Since the half-life of 137Cesium is 30.17 years, part of the radioactivity in the affected regions is still present today, and it is usually still detected in the food chain, although at lower concentration levels.

Since caesium-137 presents a long-term threat for the population of Europe and given its wide dispersion across the continent, the European Commission accepted a proposal on a joint study to compile "The Atlas of caesium contamination of Europe after the Chernobyl accident".
