Indoor radon concentration measurements were carried out and corresponding annual effective doses due to exposure to indoor radon were determined in Artvin and Ardahan provinces located in the eastern part of Turkey. The measurements were performed for four seasons in order to determine the seasonal fluctuations mostly observed in indoor environments. Indoor radon concentration values were observed to range from 21 to 321 Bq m⁻³ for the Artvin province and from 53 to 736 Bq m⁻³ for the Ardahan province. It was observed that minimum indoor radon concentration values were obtained in summer, while the highest ones were observed in winter. Indoor radon concentration values of the current study were compared with those of other provinces in Turkey. As elevated indoor radon concentrations are mostly correlated with high ²³⁸U activity concentrations in soil, a total of 57 and 33 soil samples were collected from the Artvin and Ardahan provinces, respectively, to determine ²³⁸U activity concentration as well as the concentration of ²³²Th and ⁴⁰K--naturally occurring radionuclides. It was also observed that soil samples collected from the study areas contained ¹³⁷Cs as an artificial radionuclide.
在土耳其东部的阿尔特温省和阿尔达汉省进行了室内氡浓度测量，并确定了因室内氡暴露而产生的相应年有效剂量。为了确定在室内环境中最常观察到的季节性波动，在四个季节进行了测量。阿尔特温省的室内氡浓度值在21至321 Bq m⁻³之间，阿尔达汉省的室内氡浓度值在53至736 Bq m⁻³之间。观察到夏季获得的室内氡浓度最小值，而冬季观察到最高值。将本研究的室内氡浓度值与土耳其其他省份的进行了比较。由于室内氡浓度升高大多与土壤中高²³⁸U活度浓度相关，分别从阿尔特温省和阿尔达汉省采集了57个和33个土壤样本，以确定²³⁸U活度浓度以及²³²Th和⁴⁰K（天然存在的放射性核素）的浓度。还观察到从研究区域采集的土壤样本含有作为人工放射性核素的¹³⁷Cs。
