摘要

摘要采用EpiXS软件，研究了化学处理对菲律宾天然沸石辐射屏蔽性能的影响。用x射线衍射和能量色散x射线光谱对沸石进行了研究。酸处理消除了Fe和Ca，对盐酸改性沸石的横截面有负面影响。在1332 keV下，原料沸石、NaOH改性沸石和hcl改性沸石的质量衰减系数分别为0.0545、0.0544和0.0548 cm 2 g - 1。在100-10,000 keV范围内，线性衰减系数随密度的增大而增大。NaOH-modified祝辞原始的沸石。在100 ~ 16000 keV的能量范围内，平均自由程和半值层值依次为:hcl修饰的<NaOH-modified & lt;原始的沸石。原始沸石和氢氧化钠改性沸石的有效原子序数相当，而盐酸处理沸石的有效原子序数明显较低。

Photon shielding properties of alkali- and acid-treated Philippine natural zeolite

Abstract The effects of chemical treatment on the radiation-shielding properties of Philippine natural zeolites were investigated using EpiXS following the EPICS2017 library. The zeolites were studied using X-ray diffraction and energy-dispersive X-ray spectroscopy. The acid treatment eliminated Fe and Ca, having a negative impact on the cross-section of the HCl-modified zeolite. The mass attenuation coefficients of the raw, NaOH- and HCl-modified zeolites at 1332 keV were 0.0545, 0.0544 and 0.0548 cm 2 g –1 , respectively. At 100–10,000 keV, the linear attenuation coefficient depends on the density and increases in the order HCl-modified > NaOH-modified > raw zeolite. In the energy range of 100–16,000 keV, the mean free path and half-value layer values are in the order of HCl-modified < NaOH-modified < raw zeolite. The raw and NaOH-modified zeolites have comparable effective atomic numbers, whereas the HCl-treated zeolite has significantly lower such values.
