Radiometric measurement of building materials is very important to assess the internal and external exposure caused by the ionizing radiation emitted from terrestrial radionuclides in building materials. The activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K in fifty-eight samples of fifteen different structural and covering building materials commonly used in Osmaniye province located in the Mediterranean region of Turkey were measured by using gamma-ray spectroscopy. The activity concentrations of ²²⁶Ra, ²³²Th, and ⁴⁰K varied from 2.5 ± 0.1 (marble) to 145.7 ± 4.4 (clay brick), 1.3 ± 0.1 (marble) to 154.3 ± 4.1 (marble), and 8.6 ± 0.2 (sand) to 1044.1 ± 70.3 (granite), respectively. Radiological parameters (activity concentration index, alpha index, indoor absorbed gamma dose rate and the corresponding annual effective dose rate, and excess lifetime cancer risk) were estimated to evaluate the health hazards associated with these building materials. Since the estimated values of these parameters are within the recommended safety limits or criteria values, the use of the studied building materials in the construction of dwellings can be considered to be safe for the residents of the region.

建筑材料的辐射测量对于评估建筑材料中地面放射性核素发射的电离辐射引起的内部和外部暴露非常重要。采用伽马射线光谱法测量了土耳其地中海地区奥斯马尼耶省常用的十五种不同结构和覆盖建筑材料的 58 个样品中²²⁶ Ra、²³² Th 和⁴⁰ K的活度浓度。²²⁶ Ra、²³² Th 和⁴⁰的活度浓度K 分别从 2.5 ± 0.1（大理石）到 145.7 ± 4.4（粘土砖）、1.3 ± 0.1（大理石）到 154.3 ± 4.1（大理石）和 8.6 ± 0.2（沙子）到 1044.1 ± 70.3（花岗岩）不等。估计放射学参数（活动浓度指数、α 指数、室内吸收的 γ 剂量率和相应的年有效剂量率，以及超额的终生癌症风险）以评估与这些建筑材料相关的健康危害。由于这些参数的估计值在推荐的安全限制或标准值范围内，因此在住宅建设中使用所研究的建筑材料可以被认为对该地区的居民是安全的。
