Fukushima Daiichi nuclear disaster on the International Nuclear Event Scale (INES). This scale runs from 0, indicating an abnormal situation with no safety consequences, to 7, indicating an accident causing widespread contamination with serious health and environmental effects. Prior to Fukushima, the Chernobyl disaster was the only level 7 event on record, while the Three Mile Island accident was rated as level 5. A 2012 analysis of the intermediate and long-lived radioactivity released found about 10–20% of that released from the Chernobyl disaster. Approximately 15 PBq of caesium-137 was released, compared with approximately 85 PBq of caesium-137 at Chernobyl, indicating the release of of
Cesium 137 (band) "Elemental" in 2004; it was issued with Metropolis Records, a much more prominent label than Tonedeaf.

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
