The present study was conducted in mountain regions of Armenia with the aim to assess the activity concentrations of natural K-40 and artificial Cs-137 in soil and mosses and reveal the distribution similarities and differences. Most widespread moss species and surface soils were sampled concurrently from eight mountain ridges and massifs by different altitudinal belts. Statistical analysis revealed significant differences and opposite characteristics for K-40 and Cs-137. In case of K-40 the activity concentrations decreased in mosses by altitude but with no significant correlation. The mean activity concentrations of K-40 in the soils of different altitudinal belts are close, nevertheless, the higher activity concentrations are common for soils derived from ingenious rocks. For Cs-137 in mosses, the correlation with altitude is statistically insignificant, but the altitudinal dependence is noticeable within separate ridges and massifs. A significant correlation was identified between Cs-137 in soil, altitude and precipitation rate. Studying natural K-40 and artificial Cs-137 radionuclides together yielded interesting contrasting results confirming the dissimilar behaviour of radionuclides with different origins in the environment.

本研究在亚美尼亚山区进行，旨在评估天然K-40和人工Cs-137在土壤和苔藓中的活性浓度，并揭示其分布的异同。同时从八个不同的海拔带同时从八个山脊和地块取样了最广泛的苔藓物种和表层土壤。统计分析显示K-40和Cs-137的显着差异和相反特征。在使用K-40的情况下，苔藓中的活性浓度随海拔高度而降低，但没有显着相关性。不同海拔带土壤中K-40的平均活度浓度相近，然而，较高的活度浓度对于来自天然岩石的土壤来说是常见的。对于苔藓中的Cs-137，与海拔高度的相关性在统计上微不足道，但在不同的山脊和地块中高度相关性却很明显。Cs-137在土壤，海拔和降水率之间存在显着相关性。一起研究天然K-40和人工Cs-137放射性核素产生了有趣的对比结果，证实了环境中不同来源的放射性核素的行为不同。
