Abstract
The bioconcentration factors for radiosilver (108mAg) and radiocesium (137Cs) for shiitake mushrooms from an artificially contaminated sawdust substrate were found to be 0.11 and 3.8, respectively. The main fraction of radiosilver was found in the stalk rather than the cap, whereas radiocesium accumulated mostly in the cap of the shiitake mushroom. The location of radiocesium inside the cap was analyzed by autoradiography, and the location of stable silver by LA-ICP-MS imaging. Furthermore, a method for semi-quantification of stable silver and cesium for organic solid samples was developed as an addition to the mostly qualitative autoradiography.
