See more Caesium-137 ( 55Cs ), cesium-137 (US), 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 See more Caesium-137 has a half-life of about 30.05 years. About 94.6% decays by beta emission to a metastable nuclear isomer of barium: See more Caesium-137 reacts with water, producing a water-soluble compound (caesium hydroxide). The biological behaviour of caesium is similar to that of potassium and rubidium. … See more Caesium-137 gamma sources have been involved in several radiological accidents and incidents. 1987 Goiânia, Goiás, Brazil In the See more Caesium-137 has a number of practical uses. In small amounts, it is used to calibrate radiation-detection equipment. In medicine, it is used in radiation therapy. In industry, it is used in See more Caesium-137, along with other radioactive isotopes caesium-134, iodine-131, xenon-133, and strontium-90, were released into the environment … See more • Commonly used gamma-emitting isotopes See more WebFor example, a relatively high activity 137 Cs (cesium) source was placed very close to the detector, producing a large count rate and the spectrum below. The energies of a barium x-ray (32 keV) and a cesium gamma ray (662 keV) have occasionally summed to produce a peak at 694 keV. The same is true at 1324 keV for the summing of two cesium ...
