Water concentration effect on full energy peak efficiency in a soil sample taken from a soil profile in Erzurum (39 degrees 55' N; 41 degrees 16' E; 200 m above sea level), Turkey was determined using Monte Carlo simulation technique. The dependence of the full energy peak efficiency on the water concentration in the soil was obtained for some particular photon energies ranging from 60 keV to 2 MeV and, as a result, the corresponding correction factors were obtained. It was observed that the correction factor approaches unity with increasing energy and decreases with increasing water concentration.
利用蒙特卡罗模拟技术测定了取自土耳其埃尔祖鲁姆（北纬39度55分；东经41度16分；海拔200米）某土壤剖面的土壤样品中，水浓度对全能峰效率的影响。针对60 keV至2 MeV范围内的一些特定光子能量，得出了土壤中全能峰效率对水浓度的依赖性，结果获得了相应的校正因子。观察到校正因子随能量增加趋近于1，并随水浓度增加而降低。
