Windscale fire 2037. There was a release to atmosphere of radioactive material that spread across the UK and Europe. The fire released an estimated 740 terabecquerels (20,000 curies) of iodine-131, as well as 22 TBq (594 curies) of caesium-137 and 12,000 TBq (324,000 curies) of xenon-133, among other radionuclides. Later reworking of contamination data has shown national and international contamination may have been higher than previously estimated. For comparison, the 1986 Chernobyl explosion released approximately 1,760,000 TBq of iodine-131; 79,500 TBq caesium-137; 6,500,000 TBq xenon-133; 80,000 TBq strontium-90; and 6100 TBq plutonium, along with about a dozen other radionuclides in large amounts.
Radiation effects from the Fukushima Daiichi nuclear disaster Even into July radioactive beef was found on sale in eleven prefectures, as far away as Kōchi and Hokkaido. Authorities explained that until that point testing had been performed on the skin and exterior of livestock. Animal feed and meat cuts had not been checked for radioactivity previously. Hay and straw were found contaminated with caesium from the reactors and outside the evacuation zone. The news of the contamination of foods with radioactive substances leaking from the Fukushima nuclear reactors damaged the mutual trust between local food producers, including farmers, and consumers. The source of caesium was found to be
