“…The radiocaesium concentrations have remained high in natural food products such as game meat, mushrooms and berries. It is postulated that the transfer of radiocaesium from soil via plants and mushrooms to animals is much higher in forest ecosystems than in agricultural environments, and that the radionuclide decrease is very slow [7][8][9]15].…”

¹³⁷Cs activity concentration in wild boar meat may still exceed the permitted levels

The radiocaesium activity concentration may still remain high in natural products such as game meat, wild mushrooms, and forest berries even more than two decades after the Chernobyl accident. The results of regular control studies of game meat conducted in Poland showed wild boars as the most contaminated game animals. It is well documented that some mushrooms, readily consumed by animals, show high ability to accumulate caesium radioisotopes. Bay bolete, one of the most wide-spread mushroom species in Poland, reveals a unique radiocaesium accumulation feature. Moreover, deer truffle, containing also particularly high levels of radiocaesium, could be another radionuclide source for wild boars. Furthermore, animals consuming deer truffles could digest contaminated soil components. Among 94 wild boar meat samples analysed in [2008][2009], two exceeded the permitted level. Hence, some precautions should be taken in the population with an elevated intake of wild boar meat. Moreover, since each hunted wild boar is examined for the presence of Trichinella larvae, regular measurements of radiocaesium concentrations in these animals may be advisable for enhancing consumer safety.

“…Despite the rapidly increasing economic interest in this ectomycorrhizal ascomycete, much of the hypogeous life cycle is, however, not yet fully understood (Stobbe et al, , 2013. Together with a general lack of biological and ecological insight, it is still unknown whether belowground truffle fruit bodies are accumulating radioactivity at a harmful level comparable to other fungal species and subsequent components of the trophic food web (Dighton et al, 2008;Hohmann and Huckschlag, 2005;Strebl and Tataruch, 2007;Steiner and Fielitz, 2009;Mietelski et al, 2010).…”

“…Some ectomycorrhizal and saprotrophic fungi appear particularly prone to mediating and incorporating radiocaesium-137 ( 137 Cs) (Dighton et al, 2008), with different melanin contents and mycelium depths contributing to species-specific rates of radio-resistance and 137 Cs accumulation (Mietelski et al, 2010). In regions where the aerosol fallout after Chernobyl was most intense, not only mushrooms but also later components in the food chain, including game meat of red deer, roe deer, and wild boar, still exceed the 137 Cs tolerance value of 600 Bq kg −1 (Hohmann and Huckschlag, 2005;Strebl and Tataruch, 2007;Steiner and Fielitz, 2009). …”

All-clear for gourmets: truffles not radioactive

Abstract. Although ranging among the most expensive gourmet foods, it remains unclear whether Burgundy truffles (Tuber aestivum) accumulate radioactivity at a harmful level comparable to other fungal species. Here, we measure the 137 Cs in 82 T. aestivum fruit bodies from Switzerland, Germany, France, Italy, and Hungary. All tested specimens reveal insignificant radiocaesium concentrations, thus providing an all-clear for many truffle hunters and cultivators in large parts of Europe as well as the subsequent chain of dealers and customers from around the world. Our results are particularly relevant in the light of ongoing efforts to cultivate Burgundy truffles, as well as the fact that several forest ecosystems are still highly contaminated with 137 Cs, for which mushrooms are one of the main pathways to human diets.

Ecological mechanisms can modify radiation effects in a key forest mammal of Chernobyl

et al. 2019

Nuclear accidents underpin the need to quantify the ecological mechanisms which determine injury to ecosystems from chronic low‐dose radiation. Here, we tested the hypothesis that ecological mechanisms interact with ionizing radiation to affect natural populations in unexpected ways. We used large‐scale replicated experiments and food manipulations in wild populations of the rodent, Myodes glareolus, inhabiting the region near the site of the Chernobyl disaster of 1986. We show linear decreases in breeding success with increasing ambient radiation levels with no evidence of any threshold below which effects are not seen. Food supplementation of experimental populations resulted in increased abundances but only in locations where radioactive contamination was low (i.e., below ≈ 1 μSv/h). In areas with higher contamination, food supplementation showed no detectable effects. These findings suggest that chronic low‐dose‐rate irradiation can decrease the stability of populations of key forest species, and these effects could potentially scale to broader community changes with concomitant consequences for the ecosystem functioning of forests impacted by nuclear accidents.
