摘要

结果与讨论:γ射线能谱随衰减器的有效原子序数Zeff、光子能量和固体角的变化而变化。峰总比是实验条件变化最敏感的部分，在0.663 MeV ~ 1.332 MeV范围内发生反转。这表示为反转趋势。从Zeff和实验条件的角度对结果进行了讨论。与Klein-Nishina公式和其他结果一致，低能量和大散射角下的强度积累更大。在高γ能量和小散射角下，累积因子B为1。

Broad Beam Gamma-Ray Spectrometric Studies with Environmental Materials

Results and Discussion: The γ-ray spectra vary according to changes in the effective atomic number Zeff of the attenuator, the photon energy and the solid angle. The peak to total ratios are the most sensitive parts to variations in the experimental conditions and overturn in the region 0.663 MeV to 1.332 MeV. This is indicated as inversion trend. The results are discussed in view of Zeff and the experimental conditions. The intensity build-up is larger at the lower energy and larger scattering angles in agreement with Klein-Nishina formula and other results. The buildup factor B is 1 at high γ-energies and small scattering angles.
