摘要

森林面积大，是重要的生态系统。与其他植被类型相比，它们吸收大气污染物(包括放射性核素)的能力更强。因此，监测森林生态系统中的放射性核素浓度具有重要意义。本文介绍了在塞尔维亚西南部16500公顷大面积地区进行的首次伽玛光谱测量结果。研究了该地区不同落叶乔木和常绿乔木中40K、137Cs和210Pb的活性浓度。在所有研究的同位素中，观察到的趋势是，平均活性浓度在树干中最小，而在树叶中，而在土壤中最高。统计分析显示，叶和针的活性浓度没有差异，表明叶和针都可以很好地用作生物监测仪。

Radionuclides’ content in forest ecosystem located in southwestern part of Serbia

Forests, with a large coverage of lands area, represent important ecosystem. They have greater ability to absorb atmospheric pollutant, including radionuclides compared to other vegetation types. Thus it is important to monitor radionuclides concentration in forest ecosystems. The results of the first gamma-spectrometric measurements in 16500 ha large region of South-western Serbia are presented. It is investigated activity concentrations of 40K, 137Cs and 210Pb in different deciduous and evergreen trees in the region. For all investigated isotopes, it was observed tendency that the smallest activity concentrations in average were found in tree stem, than in leaves, while the highest ones were in soil. Statistical analysis did not show any differences between activity concentrations of leaves and needles, showing that both leaves and needles could be equally well used as a biomonitors.

期刊介绍： Nuclear Technology & Radiation Protection is an international scientific journal covering the wide range of disciplines involved in nuclear science and technology as well as in the field of radiation protection. The journal is open for scientific papers, short papers, review articles, and technical papers dealing with nuclear power, research reactors, accelerators, nuclear materials, waste management, radiation measurements, and environmental problems. However, basic reactor physics and design, particle and radiation transport theory, and development of numerical methods and codes will also be important aspects of the editorial policy.
