The (239+240)Pu activity concentrations in soil from Montenegro (six samples from three localities) have been measured for the first time. The alpha and gamma-spectrometric measurements are used to determine the (239+240)Pu/(137)Cs activity ratio, and it was found to be with an average of 0.02 and standard deviation of 0.007. This average activity ratio was applied to estimate (239+240)Pu in soil samples from the other 21 localities at which (137)Cs activity concentrations were measured. In this research obtained (either experimentally or estimated) (239+240)Pu activity concentrations (0.036-8.265 Bq kg(-1)) are comparable with those measured in some other European countries. On the basis of the results obtained in the present study and a survey of relevant literature, it is possible to conclude that Chernobyl contribution to (137)Cs contamination of Montenegro soils is dominant, whilst Pu contamination comes from the global fallout of nuclear weapon tests.
首次测量了来自黑山（三个地点的六个样本）土壤中的 (239+240)Pu 活度浓度。采用 α 和 γ 能谱测量来确定 (239+240)Pu/(137)Cs 活度比，发现其平均值为 0.02，标准偏差为 0.007。该平均活度比用于估算在其他 21 个测量了 (137)Cs 活度浓度的地点的土壤样本中的 (239+240)Pu。在本研究中获得的（通过实验或估算）(239+240)Pu 活度浓度（0.036-8.265 Bq kg(-1)) 与在一些其他欧洲国家测量的结果相当。根据本研究的结果和对相关文献的调查，可以得出结论，切尔诺贝利事件对黑山土壤中 (137)Cs 污染的贡献是主要的，而 Pu 污染则来自核武器试验的全球沉降。
