The amount of radioactive cesium-137 that has so far been released by the Fukushima Daiichi nuclear disaster is equal to 168 Hiroshima atomic bombs, according to government estimates. Cesium-137 is a radioactive isotope of cesium, and is the principal source of radiation in the dead zone around the Chernobyl nuclear power plant. In a report on Thursday, the Japanese daily Tokyo Shimbun said the government calculated that the amount of cesium released in the six months since the three reactors were hit by the earthquake and tsunami is 15,000 tera becquerels.
