Urine, hair and nail samples were collected from a population of both sex aged from 40 to 87 years in Niška Banja (227 km south of Belgrade, Serbia) with a high level of natural radioactivity (HLNRA). To assess and monitor the public exposure, urine samples for each subject (24 h period) were collected and concentration of uranium (U) was analysed using alpha-particle spectrometry. Human hair and nails considered as bio-indicators of the public exposure to radionuclides over a long period of months or even years and concentration of U was determined using inductively coupled plasma-mass spectrometry. The mean concentrations of U in urine, hair and nail were 123 ng/L, 17 ng/g and 8 ng/g, respectively. There was a large variation and may be due to geological origin.
从尼什卡-巴尼亚（塞尔维亚贝尔格莱德以南227公里处）年龄在40至87岁的男女群体中采集了尿液、头发和指甲样本，该地区天然放射性水平较高（HLNRA）。为评估和监测公众暴露情况，收集了每个受试者的尿液样本（24小时时段），并使用α粒子光谱法分析了铀（U）的浓度。人体头发和指甲被视为公众在数月甚至数年的长时间内暴露于放射性核素的生物指标，并使用电感耦合等离子体质谱法测定了U的浓度。尿液、头发和指甲中U的平均浓度分别为123纳克/升、17纳克/克和8纳克/克。存在较大差异，这可能归因于地质来源。
