Abstract

137Cs activities were measured in a variety of epigeic and epiphytic lichens in Austria before and after contamination by the Chernobyl fallout. For comparison, the activity of the naturally occurring 40K was also determined in each lichen sample. The high 137Cs activities found after Chernobyl suggest that lichens are suitable and inexpensive biological detectors of the fallout pattern.

摘要

在奥地利，对切尔诺贝利核事故沉降物污染前后的多种地表和附生地衣中的铯-137活度进行了测量。作为对比，还测定了每个地衣样本中天然存在的钾-40的活度。切尔诺贝利事故后发现的高铯-137活度表明，地衣是沉降模式合适且廉价的生物探测器。
