“…Mushrooms have been reported to accumulate radiocesium (Byrne 1988 ;Kammerer et al 1994 ;Mascanzoni 1987 ;Muramatsu et al 1991 ;Sugiyama et al 1990Sugiyama et al , 1994. For example, the transfer factors (TF) for radiocesium in mushrooms were reported to be 2.6-21 in several culture tests (Muramatsu et al 1991 ;Ban-nai et al 1994 ).…”

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.

“…The ready uptake of radionuclides by plants carries them to a wide variety of foodstuffs, such as vegetables, grains, meat and dairy products. The extensive range of contamination was a characteristic of the Chernobyl fallout (Mascanzoni 1987). An understanding of the transfer from soil to plants could guide analysis of nuclide translocation through terrestrial systems, thereby improving the possibilities of forecasting the implications of a radioactive fallout for the food chain.…”

Data on the root uptake by wheat of three activation products, 54Mn, 65Zn and 63Ni, and two fission products, 90Sr and 137Cs, were obtained in a long-term field study. Soil-plant transfer factors calculated from these data were used to determine the amount of various radionuclides that may reach the humans through grain foods. The temporal variation of this contribution showed that the fraction of 54Mn and 65Zn transferred to human consumption during the first year was considerable, but owing to decay and decreasing uptake the gradients diminished and the accumulated fraction flattened to a plateau. In contrast, the fractions of the long-lived 63Ni, 90Sr and 137Cs transferred to human consumption were smaller and with nearly constant gradients. This study shows that the long-lived radionuclides are transferred to the same extent as 54Mn and 65Zn. In the long-term, the greatest doses from grain products are contributed by the long-lived radionuclides.

“…In mushrooms, the variation in activity levels between samples and species was large. In some cases 134 Cs was totally absent in the sample, which led to the conclusion that "old" fallout of 137 Cs from the nuclear weapon testing was the cause of the contamination in some cases and not the Chernobyl accident, especially in forests where the "umbrella effect" of the trees made the deposition very inhomogeneous (Mascanzoni, 1987).…”
