Will Fukushima now officially be referred to as worst nuclear disaster in world history? Study estimates Japan plant released 100 quadrillion becquerels (PBq) of cesium into atmosphere… In a single day

Wikipedia’s entry on Chernobyl states, “20 to 40% of all core caesium-137 was released, 85 PBq in all.” The source cited is Chernobyl: Assessment of Radiological and Health Impact -Nuclear Energy Agency (NEA)

The same source gives another amount for the Chernobyl release that is considerably less, “However, more deposition data were available when, in their 1988 Report, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) gave release figures based not only on the Soviet data, but also on worldwide deposition. The total 137Cs release was estimated to be 70 petabecquerels (PBq)” -Nuclear Energy Agency’s 2002 assessment of the Chernobyl disaster

According to the Committee on an Assessment of CDC Radiation Studies, National Research Council: “35 PBq of Cs-134 and 70 PBq of Cs-137 were released into the atmosphere” at Chernobyl.

Fukushima’s total cesium releases are considerably higher than the 100 PBq stated in the July 2012 study, as that included only atmospheric releases and none of the plant’s record discharges into the ocean (up to 47 quadrillion becquerels)… and it is only based on the amount from a single day.
