Activity of cesium-134 and cesium-137 in game and mushrooms in Poland

The activity of cesium-134 and cesium-137 was measured in mushrooms and game in 1986–1991. The samples were collected all over Poland and most of measurements were carried out for export purposes. The results indicate that the activity ratio of cesium-137 to cesium-134 in some samples is not comparable to that in fallout after the Chernobyl accident. The analysis of some samples of mushrooms from 1985 showed that the activity of cesium-137 was higher compared to any other foodstuff. The level of contamination varied greatly throughout Poland.
