Results from recent measurements of radiation gamma background at high mountain altitude, namely at Basic Environmental Observatory Moussala (42.11 N, 23.35 E, 2925 m a.s.l.) are reported. The measurements are fulfilled with several devices, namely IGS-421 gamma probe and MDU Liulin. A comparative analysis with previous measurements performed with SBN-90 SAPHYMO NaI(Tl) gamma probe is carried out. A temperature effect during winter period of SAPHYMO probe is observed. In addition the measurements are compared with CaSO(4):Dy TLD. The obtained results are widely discussed. A numerical model for galactic cosmic ray contribution to the dose rate in air is presented. The model is based on a full Monte Carlo simulation of cosmic ray induced cascade in the atmosphere. The simulation is carried out with CORSIKA 6.52 code using FLUKA 2006b and QGSJET II hadron interaction models.
报告了在高海拔山区（42.11°N，23.35°E，2925 m 海拔）进行的辐射γ背景测量的结果。使用了几种设备进行测量，即 IGS-421 伽马探头和 MDU 柳林。与之前使用 SBN-90 SAPHYMO NaI(Tl) 伽马探头进行的测量进行了比较分析。观察到 SAPHYMO 探头在冬季期间存在温度效应。此外，还将测量结果与 CaSO(4):Dy TLD 进行了比较。对获得的结果进行了广泛的讨论。提出了一个用于计算空气中剂量率的银河宇宙射线贡献的数值模型。该模型基于在大气中进行宇宙射线诱导级联的全蒙特卡罗模拟。使用 CORSIKA 6.52 代码，使用 FLUKA 2006b 和 QGSJET II 强子相互作用模型进行了模拟。
