Radioactivity : Chernobyl Caesium

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).On the contrary, because of their periods of thirty years, the effects of cesium-137, and to a lesser degree those of one other

Local despair over Fukushima's radioactive mushrooms

Japan's standard for radioactive cesium in general food is 100 becquerels per kilogram. The levels in Tanagura's matsutake mushrooms are still three times that. Tanagura's matsutake had a

Cesium

Cesium Cs 137 is a radioactive isotope of cesium with an atomic mass of 139 and potential application in radiotherapy. Cesium Cs 137 is prevalent due to its spontaneous production, which occurs as a result of nuclear fission of other radioactive materials, such as uranium and plutonium.This radionuclide has a relatively long half-life, 30 years, and decays by emitting beta particles.

High radioactive cesium levels detected in worms 20 km

Radioactive cesium registering some 20,000 becquerels per kilogram has been found in worms 20 kilometers from the damaged Fukushima No. 1 nuclear plant. The cesium was detected by a team including Motohiro Hasegawa, chief researcher in soil zoology at Japan's Forestry and Forest Products Research Institute.

Radionuclide Basics: Cesium

Jul 14, 2021Jul 14, 2021Radionuclide Basics: Cesium-137. Cesium (chemical symbol Cs) is a soft, flexible, silvery-white metal that becomes liquid near room temperature, but easily bonds with chlorides to create a crystalline powder. The most common radioactive form of cesium is Cs-137. Cesium-137 is produced by nuclear. fission The splitting of an atomic nucleus into

Caesium

Caesium-137 (137 55 Cs), or radiocaesium, is a radioactive isotope of caesium that 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.Trace quantities also originate from natural fission of uranium-238.It is among the most problematic of the short-to-medium-lifetime fission products.
