1984-1988 年期间，对同一地区的各种蘑菇以及一些森林土壤样本中测定了自然产生的 40K 和 137C 的浓度。切尔诺贝利反应堆事故发生前，蘑菇中的 137Cs 含量普遍低于 500 Bq kg-1 干物质，但卷状芽孢杆菌除外 /2700 Bq kg-1/。 1986 年观察到 137Cs 活性显着增加/高达十倍。对于几乎所有检查的物种，该活性在接下来的两年中基本保持在同一水平。蘑菇中的 40K 和 137C 之间没有发现相关性。
The concentration of naturally occurring 40K and 137Cs from fallout were determined in various mushrooms as well as in a few samples of forest soil from the same region over the period of 1984-1988. The 137Cs content in mushrooms before the reactor accident at Chernobyl was generally below 500 Bq kg-1 dry matter, except Paxillus involutus /2700 Bq kg-1/. A remarkable increase of the 137Cs activity/up to ten times/ was observed in 1986. For almost all examined species this activity remained basically at the same level for the next two years. No correlation between 40K and 137Cs in mushrooms has been found.
