From September to December of 1986, 85 samples of 34 species of wild mushrooms were collected, mostly in northern Baden and occasionally in neighboring areas. Cs-137, Cs-134, and the natural nuclide K-40 were determined by gamma-spectrometry. Samples from the Rhine Valley and the Kraichgau were generally much less contaminated than those from the Black Forest. With one exception, their radiocesium levels were below the Common Market limit of 600 Bq/kg. The exception was a sample of Laccaria amethystina with 1710 Bq/kg Cs-137 and 766 Bq/kg Cs-134. Relatively high levels were also found in Xerocomus badius, X. chrysenteron and Cantharellus tubaeformis. The hymenophore contained higher concentrations of radiocesium than the other parts of the body of the fruit. No correlation between the concentration of K-40 and that of the Cs nuclides was found. The ratio of Cs-137:Cs-134 was usually below 3 but reached the value of 11.8 in Piptoporus betulinus growing on birch wood. In this case, the substrate must have contained more radiocesium from the time before the Chernobyl reactor accident than from the time thereafter.
1986年9月至12月，共采集了34种野生蘑菇的85个样本，大部分采自巴登北部，偶尔也在邻近地区采集。通过伽马能谱法测定了铯-137、铯-134和天然核素钾-40。莱茵河谷和克莱希高地区的样本污染程度通常远低于黑森林地区的样本。除一个样本外，它们的放射性铯含量均低于共同市场规定的600贝克勒尔/千克的限值。这个例外是一个紫晶蜡蘑样本，其铯-137含量为1710贝克勒尔/千克，铯-134含量为766贝克勒尔/千克。在褐疣柄牛肝菌、金黄疣柄牛肝菌和喇叭菌中也发现了相对较高的含量。子实层含有的放射性铯浓度高于子实体的其他部分。未发现钾-40浓度与铯核素浓度之间存在相关性。铯-137与铯-134的比值通常低于3，但在生长于桦木上的桦褶孔菌中该比值达到了11.8。在这种情况下，该基质在切尔诺贝利反应堆事故之前所含的放射性铯肯定比事故之后更多。
