Radioactive contamination of wild mushrooms - current measured values
|
|
Many people enjoy wild mushrooms as a tasty contribution to their menu. But even more than two decades after the reactor accident of Chernobyl, the Federal Office for Radiation Protection measures enhanced activities of the radionuclide cesium-137 in some mushroom species.
The measurement campaigns from 2005 to 2011 focused on Southern Germany, a region especially affected by the reactor accident of Chernobyl. The activity levels of Lactarius volemus (Weeping Milky), Lactarius lignyotus (Chocolate Milky), Hydnum rufescens (Terracotta Hedgehog), Hydnum repandum (Wood Hedgehog), Cantharellus tubaeformis (Trumpet Chanterelle) and Hygrophorus agathosmus (Gray Almond Waxy Cap) exceeded 1,000 becquerels per kilogram cesium-137 during the past three years.
With measured values below 5 becquerels per kilogram cesium-137 in the same period of time, Coprinus atramentarius (Inky Cap), Melanoleuca cognata (Spring Cavalier), Lepista flaccida (Tawny Funnel), Russula aurea (Gilded Brittlegill), Russula undulata (Blackish-purple Russula), Agaricus essetei, Russula lepida (Rosy Russula) and Macrolepiota konradii s.l. (Konrads Parasol) were only slightly contaminated.
