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

Popis výsledku v původním jazyce

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.
