Radiation effects from the Fukushima Daiichi nuclear disaster PBq of caesium-137. In May 2012, TEPCO reported that at least 900 PBq had been released "into the atmosphere in March last year [2011] alone" up from previous estimates of 360-370 PBq total. The primary releases of radioactive nuclides have been iodine and caesium; strontium and plutonium have also been found. These elements have been released into the air via steam; and into the water leaking into groundwater or the ocean. The expert who prepared a frequently cited Austrian Meteorological Service report asserted that the "Chernobyl accident emitted much more radioactivity and a wider diversity of radioactive elements than Fukushima
Radiation effects from the Fukushima Daiichi nuclear disaster fish was 510,000 Bq/kg detected in another greenling. On the sea floor a net was installed by TEPCO, in order to prevent migrating fish to escape from the contaminated area. As of July 2011, the Japanese government has been unable to control the spread of radioactive material into the nation's food, and "Japanese agricultural officials say meat from more than 500 cattle that were likely to have been contaminated with radioactive caesium has made its way to supermarkets and restaurants across Japan". On 22 July it became known that at least 1400 cows were shipped from 76 farms that were
