Radioactivity : Caesium 137

2016-6-26  Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions. A lot of attention is focused on caesium 137 : it is the main source of long term contaminations after atmosphric tests of atomic bombs
