In situ indoor gamma dose rate measurements were held in 79 dwellings by NaI(Tl) scintillation probe connected portable dose rate meter. For the building materials and impurities (nodules), spectrometric gamma analysis was applied by a high-resolution HpGe detector. For Ahmetçe and Nusratlı villages in Ayvacik/Çanakkale (Turkey), the measured in situ indoor gamma dose rates and related indoor annual effective dose equivalents (AEDE_in) were 3 and 3.3 times, and indoor excess lifetime cancer risks (ELCR_in) were 4.25 and 4.68 times higher than those of the world averages, respectively. The used local rocks were mostly ignimbrite and dacitic–rhyolitic tuffaceous (Arıklı tuff), and wall plasters were made of local soil. The highest in situ indoor gamma dose rates of the region belonged to Nusratlı village due to the intense impurities (nodules) and hydrothermal alterations in Arıklı tuff. Spectrometric gamma results revealed that ⁴⁰K has an important effect on the indoor gamma doses.

本地建筑材料对室内伽玛剂量和相关的辐射健康风险的影响，阿瓦维克，恰纳卡莱/土耳其。

通过NaI（Tl）闪烁探针连接便携式剂量率仪在79处住宅中进行室内伽马剂量率原位测量。对于建筑材料和杂质（结核），通过高分辨率HpGe检测器进行了伽玛光谱分析。在艾瓦哲克/（土耳其）Ahmetçe和Nusratlı村庄，所测量的原位室内伽马剂量率和相关室内年有效剂量当量（AEDE_中）中3个3.3倍，而室内过量寿命的癌症风险（ELCR_中）分别为4.25比世界平均水平高4.68倍。所用的当地岩石主要是易燃物和大规-流纹质凝灰岩（Arıklı凝灰岩），墙面灰泥是用当地土壤制成的。最高的由于Arıklı凝灰岩中强烈的杂质（结节）和水热变化，该地区的原位室内伽马剂量率属于Nusratlı村。伽玛光谱结果表明，⁴⁰ K对室内伽玛剂量具有重要影响。
