Seems like it would be completely fine to eat, even regularly. With mushrooms having 1000 Bq/kg at worst, according to samples by BfS. > The consumption of 200 grams of mushrooms with 2,000 becquerel caesium-137 per kilogram results in an exposure of 0.005 millisievert. This is considerably less than the radiation exposure during a flight from Frankfurt to Gran Canaria. However, if adults eat such a mushroom meal each week, they will receive an additional annual radiation exposure corresponding to about twenty flights from Frankfurt to Gran Canaria. Expressed in numbers it is 0.27 millisievert. https://www.bfs.de/EN/topics/ion/environment/foodstuffs/mushrooms-game/mushrooms-game_node.html https://www.bfs.de/EN/topics/ion/environment/foodstuffs/mush...
