Long-term 137cs activity monitoring of mushrooms in forest ecosystems of the Czech Republic

Original language description

This paper reports on results of activity mass concentration analyses performed in various forest mushrooms in the Czech Republic within 1986 and 2011. The estimated effective half-life of 137Cs and its environmental half-life were found to be 5.6?0.6 and 6.9?0.7 y, respectively. Non-homogeneity in 137Cs surface contamination over the country?s territory and fungus species-based 137Cs accumulation capacity then account for a span of up to 4 orders of magnitude in activity mass concentrations measured each year after the Chernobyl accident. The highest geometric activity mass concentration (Bq/kg of dry weight) means of 137Cs (obtained from samples between years 2004 and 2011) were measured in Suillaceae (1050 Bq/kg) and Boletus badius (930 Bq/kg), thelowest in Agaricus (1 Bq/kg). The geometric mean of all mushrooms amounted to 230 Bq/kg, being 440 Bq/kg in Boletales, 150 Bq/kg in Russulales and 21 Bq/kg in Agaricales.
