This study focuses on the radiological characterisation of building materials manufactured in Albania by using a high-resolution gamma-ray spectrometer. The average activity concentrations of (40)K, (226)Ra and (232)Th were, respectively, 644.1±64.2, 33.4 ± 6.4 and 42.2 ± 7.6 Bq kg(-1) in the clay brick samples and 179.7 ± 48.9, 55.0 ± 5.8 and 17.0 ± 3.3 Bq kg(-1) in the cement samples. The calculated activity concentration index (ACI), varied from 0.48±0.02 to 0.63±0.04 in the clay brick samples and from 0.29±0.03 to 0.37±0.02 in the cement samples. Based on the ACI, all of the clay brick and cement samples were categorised as A1 materials. The authors can exclude (at 3σ level) any restriction of their use as bulk materials.
本研究聚焦于使用高分辨率伽马射线光谱仪对阿尔巴尼亚制造的建筑材料进行放射性表征。粘土砖样品中（40）K、（226）Ra和（232）Th的平均活度浓度分别为644.1±64.2、33.4±6.4和42.2±7.6 Bq kg⁻¹，水泥样品中分别为179.7±48.9、55.0±5.8和17.0±3.3 Bq kg⁻¹。计算得出的活度浓度指数（ACI）在粘土砖样品中为0.48±0.02至0.63±0.04，在水泥样品中为0.29±0.03至0.37±0.02。基于ACI，所有粘土砖和水泥样品均被归类为A1材料。作者可以排除（在3σ水平）其作为散装材料使用的任何限制。
