| 摘 要： | 地衣植物对放射性物质具有富集作用,在国内有关这方面的研究工作尚未见有报道。本文作者对采自不同地区的22种地衣进行了低本底α,β射线总放射性的测定和NaI(TL)γ能谱的分析,结果表明:地衣中长寿命放射性核素有明显的积累现象,并呈现出一定的空间分布趋势。因而,了解地衣体中放射性含量水平、核素性质及分布状况,进而为研究环境放射学、地衣污染生态学等学科提供科学依据和基础资料。

| Abstract: | Radioactivity can be concentrated by lichens. However, no research on this phenomenon has been reported in China.By using lowbackground instrument, the authors measured a,βtotal radiation in 22 species of lichens collected from different areas in China, and analyzed the energy spectra of Nal(Tl). Marked accumulation of long-lived radioisotopes in lichens, with a trend of space distribution, has been shown in this study. It is necessary to understand the radiation level and distribution of the radioisotopes for providing some basic data in studies on environment radiology and ecology of lichen polluted by radioactive fallout. |
