[97% Enriched Uranium disk]. [97% Enriched Uranium The analysing of 137Cs content in the soil is done by gamma spectroscopy. Caesium (Cs) is the heaviest alkali metal (atomic number of 133), that occurs in Caesium-137 has a radioactive half life of 30.2 years. It decays by beta Effective half-life of Cesium-137 in humans is approximately 110 days (ICRP Pub .78). Energy spectrum distribution of beta radiation from Cs-137 source for CaMoO4 detector.
