“…NWT affected the wild mushrooms in Japan, more than the Chernobyl accident. The contribution of Chernobyl accident was estimated to be in the range of 7-60% and 10-30% on an average (Igarashi and Tomiyama 1990 ;Muramatsu et al 1991 ;Shimizu et al 1997 ; Cs deposition 50 years ago was thrice as high as the present levels.…”

High concentrations of radionuclide contamination of wild mushrooms occurred near the Fukushima Daiichi nuclear power plant and along the path of radioactive plumes. This is a serious problem for the forest ecosystem and commercial wild mushroom production. Radioactivity in wild mushrooms collected from low-level contamination forest areas throughout Japan was measured approximately 6 months after the accident. In general, the radioactivity in mushrooms did not exceed those in the neighboring forest litter. However, further accumulation of 137 Cs is expected in mushrooms; therefore, continuous monitoring is necessary even in low-contamination areas. We also found that residual 137 Cs radioactivity due to nuclear weapons tests, mainly in 1950s, besides fallout from the Fukushima nuclear accident still remained in soil and was accumulated by mushrooms.

In comparison with the 1993 ASIASARI R. samples, the variation in 137 Cs values among the same species obtained between 2000 and 2001 was smaller.…”

“…NWT affected the wild mushrooms in Japan more than the Chernobyl accident. The contribution of the Chernobyl accident was estimated to be in the range of 7-60% and 10-30% on average in each study (Igarashi and Tomiyama 1990;Muramatsu et al 1991;Shimizu et al 1997;). In the current study, ecological features of radioactive contamination in mushrooms and in soils were discussed by comparing the contamination from the Fukushima accident with those from NWT and the Chernobyl accident.…”
