Agricultural implications of the Fukushima nuclear accident

More than 4 years has passed since the accident at the fukushima nuclear power plant. immediately after the accident,40 to 50 academic staff of the graduate school of agricultural and life sciences at the university of tokyo created an independent team to monitor the behavior of the radioactive materials in the field and their effects on agricultural farm lands,forests,rivers,animals,etc. when the radioactive nuclides from the nuclear power plant fell,they were instantly adsorbed at the site where they first touched; consequently,the fallout was found as scattered spots on the surface of anything that was exposed to the air at the time of the accident. the adsorption has become stronger over time,so the radioactive nuclides are now difficult to remove. the findings of our study regarding the wide range of effects on agricultural fields are summarized in this report. © 2016 the author 2016. published by oxford university press on behalf of the japan radiation research society and japanese society for radiation oncology.
