Abstract

To establish the radioactivity level of soils and assess the associated radiological impact on residents, 58 samples from the town of Bitola and its environs were collected. After conducting gross alpha and gross beta measurements with a gas-flow proportional counter as a preliminary screening test, subsequent gamma-spectrometry measurements reveal the presence of ⁴⁰K, ²²⁶Ra, ²³²Th, and ¹³⁷Cs in the soil samples as radionuclides with the highest impact. The absorbed gamma dose rate, the annual effective dose, radium equivalent activity, external hazard index, gamma index, excess lifetime cancer risk, and annual gonadal dose were calculated using the obtained activity concentrations of the radionuclides. Upon comparison with similar studies conducted in the Balkan countries, the obtained results for radiation hazard indices were found to be the highest in the region. Coloured maps were generated to visually represent the spatial distribution of the absorbed gamma dose rate in air and annual effective dose, clearly indicating the combined influence of geology and human activities, including the nearby thermoelectric power plant operation.

评估比托拉市（马其顿）及其周边地区土壤的放射性危害。

为了确定土壤的放射性水平并评估对居民的相关辐射影响，从比托拉镇及其周边地区采集了 58 个样本。在使用气流比例计数器进行总阿尔法和总贝塔测量作为初步筛选测试之后，随后进行的伽马谱仪测量显示，土壤样本中的 40K、226Ra、232Th 和 137Cs 是影响最大的放射性核素。根据所获得的放射性核素活度浓度，计算了吸收伽马剂量率、年有效剂量、镭当量活度、外部危害指数、伽马指数、终生致癌超额风险和年性腺剂量。在与巴尔干国家进行的类似研究进行比较后，发现所获得的辐射危害指数结果是该地区最高的。绘制了彩色地图，直观地显示了空气中吸收的伽马剂量率和年有效剂量的空间分布情况，清楚地表明了地质和人类活动（包括附近热电厂的运行）的综合影响。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
