| Outline of Final Research Achievements |
After the Fukushima Daiichi nuclear disaster 4 years, a bio-monitoring of radioactivity in mushrooms, lichens and plant parasitic fungi were conducted mainly in Ibaraki, fewer in Fukushima, Tochigi, Miyagi and Chiba Prefecture. The results show that in mushrooms the mycorrhizal species are higher than saprotrophic one, in lichens in mean the radioactivity are 10 fold higher than mushrooms, and in plant parasitic fungi the radioactivity of Exobasidium vaccinii which cause Azalea leaf galls are 2-fold higher than healthy leaves. Finally, at the present the rate of decreasing of 137Cs radioactivity is lower than after 2 years of the disaster, is now stable and still high.
