In this study, the natural radioactivity levels were determined for the deep mud samples taken from Van Lake. 226 Ra, 232 Th and 40 K natural radionuclides concentration analysis were performed using high-purity germanium detector and relevant radiological hazard parameters were also appraised. Furthermore, the concentrations of heavy metals were measured using ICP–OES device. While the average 226 Ra, 232 Th activity concentrations were higher than the world average values, the average 40 K concentration was lower than the world average. The average metal concentrations were found to be higher than the highest effective levels reported in national and international quality guidelines (except Cr and Zn).

土耳其凡湖深泥样品中天然放射性核素和重金属污染的放射危害评价

在这项研究中，确定了取自 Van Lake 的深层泥浆样品的天然放射性水平。使用高纯锗探测器进行了226 Ra、232 Th和40 K天然放射性核素浓度分析，并对相关放射危害参数进行了评价。此外，使用 ICP-OES 设备测量重金属浓度。226 Ra、232 Th的平均活性浓度高于世界平均值，40 K的平均浓度低于世界平均值。发现平均金属浓度高于国家和国际质量指南中报告的最高有效水平（Cr 和 Zn 除外）。
