Mushrooms, the moos/grass layer and soil samples have been collected in autumn 1987 from two sites in SW-Bavaria in continuation of a former investigation (Elstner et al. 1987). There were still relatively high amounts of Cs and Cs in all samples. The ratio Cs/Cs changed according to the different half-life times of the two radioisotopes, indicating in nearly all cases the Chernobyl accident as source. The distribution of the radioisotopes within the mushroom populations shows considerable variation, even within the same species and location. Besides Cs, Cs and K no other radioisotopes were detected.
1987年秋，在巴伐利亚西南部的两个地点采集了蘑菇、苔藓/草层和土壤样本，作为之前一项调查（埃尔斯特纳等人，1987年）的延续。所有样本中仍含有相对大量的铯-134和铯-137。铯-134/铯-137的比值因这两种放射性同位素不同的半衰期而变化，几乎在所有情况下都表明切尔诺贝利事故是其来源。放射性同位素在蘑菇种群中的分布显示出相当大的差异，即使在同一物种和同一地点也是如此。除了铯-134、铯-137和钾之外，未检测到其他放射性同位素。
