Determinations of 210Pb contents in food, diet, environmental samples and estimations of internal dose due to daily intakes

On the occurrence, origin, and intake of the nuclides, 210Po and 210Pb, in sclerotia of Wolfiporia cocos collected in China

“…However, in the case of the external part consumption, it might be much higher and result in an annual effective dose of 0.88 µSv a −1 dw to 0.70 mSv a −1 dw from 210 Po decay while of 0.58 µSv a −1 dw to 0.22 mSv a −1 dw from 210 Pb decay. The calculated values of effective doses from 210 Po and 210 Pb ingestion with W. cocos are similar or lower (in the case of inner parts) in comparison to other studies of wild fungi from other parts of the world (Hendry et al, 2009;Vaaramaa et al, 2009;Gwynn et al, 2013;Guillén and Baeza, 2014;Bagchi and Swaroop, 2016;Strumińska-Parulska et al, 2016; Pang et al, 2019;Poschl and Nollet, 2019;Strumińska-Parulska and Falandysz 2020). In general, when consumed with staple foodstuffs, the analyzed sclerotia would not significantly increase the values of the effective radiation doses from 210 Po and 210 Pb isotopes.…”
