It is this decay product that makes cesium an external hazard (that is, a hazard without being taken into the body). Cesium … Caesium-134 has a radioactive half life of 2.06 years. It decays by beta emission, yielding one beta particle per transformation with a mean energy of 0.157 MeV. It also emits an average of 2.23 gamma rays per transformation with a mean energy of 0.698 MeV. Caesium-137 … 1987-09-13 CESIUM 137 AND ITS GAMMA RADIATION IN TELERADIOTHERAPY R. THORAEUS Up till now more than one thousand radioactive isotopes have been arti- ficially produced, and the properties of their radioactivities are fairly well known. Among them, however, only a very few have attracted interest as re- gards radiotherapy application.
