Fukushima Daiichi nuclear disaster for caesium-137, which is about 11% of Chernobyl emissions. Earlier estimations were 150 PBq and 12 PBq. In 2011, scientists working for the Japan Atomic Energy Agency, Kyoto University and other institutes, recalculated the amount of radioactive material released into the ocean: between late March through April they found a total of 15 PBq for the combined amount of iodine-131 and caesium-137, more than triple the 4.72 PBq estimated by TEPCO. The company had calculated only the direct releases into the sea. The new calculations incorporated the portion of airborne radioactive substances that entered the ocean as rain. In the

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
