Abstract

The (90)Sr activity concentrations released from a radioactive fallout have been determined in a range of samples of mushrooms collected in Poland, Belarus, China, and Sweden in 1996-2013. Measurement of (90)Sr in pooled samples of mushrooms was carried out with radiochemical procedure aimed to pre-isolate the analyte from the fungal materials before it was determined using the Low-Level Beta Counter. Interestingly, the Purple Bolete Imperator rhodopurpureus collected from Yunnan in south-western China in 2012 showed (90)Sr activity concentration at around 10 Bq kg(-1) dry biomass, which was greater when compared to other mushrooms in this study. The King Bolete Boletus edulis from China showed the (90)Sr activity in caps at around 1.5 Bq kg(-1) dry biomass (whole fruiting bodies) in 2012 and for specimens from Poland activity was well lower than 1.0 Bq kg(-1) dry biomass in 1998-2010. A sample of Sarcodonimbricatus collected in 1998 from the north-eastern region of Poland impacted by Chernobyl fallout showed (90)Sr in caps at around 5 Bq kg(-1) dry biomass. Concentration of (90)Sr in Bay Bolete Royoporus (Xerocomus or Boletus) badius from affected region of Gomel in Belarus was in 2010 at 2.1 Bq kg(-1) dry biomass. In several other species from Poland (90)Sr was at <0.5 to around 1.0 Bq kg(-1) dry biomass. Activity concentrations of (90)Sr in popular B. edulis and some other mushrooms collected from wild in Poland were very low (<1 Bq kg(-1) dry biomass), and values noted showed on persistence of this type of radioactivity in mushrooms over time passing from nuclear weapons tests and the Chernobyl nuclear power plant catastrophe.
