Radiation effects from the Fukushima Daiichi nuclear disaster times the safety limit, Professor Yasuyuki Muramatsu at the Gakushuin University urged detailed checks on wild plants and animals. Radioactive caesium in soil and fallen leaves in forests in his opinion would be easily absorbed by mushrooms and edible plants. He said that wild animals like boars were bound to accumulate high levels of radioactivity by eating contaminated mushrooms and plants. The professor added that detailed studies were on wild plants and animals. Across Europe the Chernobyl-incident had likewise effects on wild fauna and flora. The first study of the effects of radioactive contamination following the Fukushima Daiichi nuclear disaster
Caesium-137 larger factors. In April 2011, elevated levels of caesium-137 were also being found in the environment after the Fukushima Daiichi nuclear disasters in Japan. In July 2011, meat from 11 cows shipped to Tokyo from Fukushima Prefecture was found to have 1,530 to 3,200 becquerels per kilogram of Cs-137, considerably exceeding the Japanese legal limit of 500 becquerels per kilogram at that time. In March 2013, a fish caught near the plant had a record 740,000 becquerels per kilogram of radioactive caesium, above the 100 becquerels per kilogram government limit. A 2013 paper in "Scientific Reports" found that for a
