Environmental radioactivity study of Austrian and Bavarian forest ecosystems: Long-term behaviour of contamination of soil, vegetation and wild boar and its radioecological coherences.

Cs and K in soil, vegetation and flesh of wild boar samples from Austrian and Bavarian regions were investigated by gamma-ray spectrometry and Sr in bones of wild boar with Liquid Scintillation Counting (LSC) after radiochemical separation. The soil core profiles revealed that 70-97% of the soil caesium content is still accumulated in the 0-10cm soil depth. From all vegetation samples the mushrooms, particularly the bay boletus showed the highest Cs contamination.
