cesium 137 release

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

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.

FACT SHEET: EPA FACTS ABOUT CESIUM-137

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.

Apr 02, 2016· Cesium-137 has an atomic number of 55, so is written as #""_55^137Cs#. It is also a #beta#-emitter, which means it undergoes #beta#-decay by a neutron decaying into a proton, releasing an electron.. Protons and neutrons have the same mass, so the mass number doesn't change. The atomic number increases by one, because one more proton is formed.
