Abstract

The primary objective of this study is to determine the levels of natural radioactivity (²³⁸U, ²³²Th and ⁴⁰K) in 46 rock samples collected from the Central Pontides region (Central Anatolia). The radioactivity of rocks is crucial in geology, not only for assessing environmental radiation exposure and its potential health effects but also for monitoring groundwater quality and identifying geothermal energy sources. The specific activity values were determined using a calibrated high-purity germanium detector (HPGe). The calculation of basic radiological risk parameters was also undertaken. The analysis revealed that volcanic and plutonic rock samples exhibited elevated levels of specific activity for ⁴⁰K, ²³⁸U, and ²³²Th, while the lowest radioactivity levels were observed in ultramafic rock formations.

从中央池塘采集的岩石样本的放射性水平测定和放射性风险评估（土耳其中部安纳托利亚）

本研究的主要目的是确定从中央庞泰德地区（安纳托利亚中部）收集的46个岩石样本中的天然放射性（238U， 232Th和40K）水平。岩石的放射性在地质学中是至关重要的，不仅用于评估环境辐射暴露及其潜在的健康影响，而且用于监测地下水质量和查明地热能源。比活度用校准的高纯度锗检测器（HPGe）测定。并进行了基本辐射风险参数的计算。分析表明，火山和深部岩石样品中40K、238U和232Th的放射性水平较高，而超镁铁性岩层的放射性水平最低。
