The mushroom samples gathered in forest ecosystems were contaminated by the post-Chernobyl radiocesium. The activity concentrations of 137Cs were determined by the semiconductor gammaspectroscopy. It was proved that the reduction in activity has been affected by the frequency of replacement of acetic acid.
