- Abstract
A total of 505 mushrooms belonging to 9 species were collected in the 2017 and 2018 mushrooming seasons near Dolní Rožínka in the Bohemian-Moravian Highlands and analysed by gamma spectrometry for 137Cs activity. The greatest 137Cs activity of 575 Bq kg-1 was detected in the species Boletus edulis, which is just below the permitted limit in its native state. In contrast, the detected activity level was only 316 Bq kg-1 in the mushroom Imleria badia, which is reported to be associated with the highest cumulative capability of all fungi species. However, differences in mean contamination values were not significant (p <0.05) due to high variability. It was shown that activity concentration is not dependent on the weight (size) of Imleria badia. Our results also confirmed the generally well known lower 137Cs activity in Russula species belonging to the group of gill-bearing or lamella-bearing mushrooms.
