Penny bun (Boletus edulis) and chanterelle (Cantharellus cibarius) are fungi
used for human consumption in several forms: fresh, thermally treated, or
conserved (salted, marinated, pasteurized, dried). Random samples were
collected on the territory of the Republic of Serbia in the period 1999-2018
intended for export to the EU. The presence of 137Cs was noted in each
individual fungi sample. The higher activity level of 137Cs in fresh penny
bun samples was noted in 2001 (25.9 Bqkg–1), while in fresh chanterelle
samples it was noted in 2000 (18.6 Bqkg–1). Marinating the fungi reduced
activity levels of 137Cs in relation to the fresh fungi activity, for penny
bun from 1.6 to 12.6 times for a year, while for chanterelle from 0.8 to 14.7
times for a year. Drying the fungi increases activity levels of 137Cs: for
penny bun from 0.04 to 0.29 times for a year, while for chanterelle from 0.03
to 1.94 times for a year. The values of annual effective radiation doses were
much lower than the recommended values for the population (1 mSv).
