Alkali metal from the Chernobyl accident. Caesium-137 undergoes high-energy beta decay and eventually becomes stable barium-137. It is a strong emitter of gamma radiation. Caesium-137 has a very low rate of neutron capture and cannot be feasibly disposed of in this way, but must be allowed to decay. Caesium-137 has been used as a tracer in hydrologic studies, analogous to the use of tritium. Small amounts of caesium-134 and caesium-137 were released into the environment during nearly all nuclear weapon tests and some nuclear accidents, most notably the Goiânia accident and the Chernobyl disaster. As of 2005, caesium-137 is the principal source
Cesium 137 (band) "Elemental" in 2004; it was issued with Metropolis Records, a much more prominent label than Tonedeaf. It was soon followed by an E.P. release, "Luminous", also in 2004 on Metropolis; it composed largely of remixed material from "Elemental". Cesium_137's style was much mellower and synthpop inspired and less angst-ridden on these releases than on "Advanced/Decay". In 2006, Cesium_137 released their album "Intelligent Design". Like its predecessor, it was released by Metropolis. Cesium_137 is named after a radioactive isotope of caesium. It continues a tradition in industrial music of incorporating a number in the band name, which became popular after the
