Abstract
The WinXCom program has been used to calculate the mass attenuation coefficients (μm), effective atomic numbers (Zeff), effective electron densities (Nel), half-value layer (HVL), and mean free path (MFP) in the energy range 1 keV–100 GeV for Gd3Al2Ga3O12Ce (GAGOC) and CaMoO4 (CMO) scintillator materials. The geometrical progression (G-P) method has been used to compute the exposure buildup factors (EBF) and gamma ray energy absorption (EABF) in the photon energy range 0.015–15 MeV and up to a 40 penetration depth (mfp). In addition, the values of the removal cross section for a fast neutron ∑R have been calculated. The computed data observes that GAGOC showed excellent γ-rays and neutrons sensing a response in the broad energy range. This work could be useful for nuclear radiation sensors, detectors, nuclear medicine applications (medical imaging and mammography), nuclear engineering, and space technology.
Highlights
Due to the great importance of inorganic scintillator materials in the field of ionizing nuclear radiation detection, they are a very suitable to utilize in many applications such as technology of space, the design of nuclear devices, and medicinal diagnostics [1]
When the gamma ray interacts with the material, the half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Nel), exposure buildup factors (EBF), and gamma ray energy absorption (EABF) are the fundamental quantities required to explain the penetration of nuclear radiation in matter
HVL, MFP, Zeff, Nel, EBF, and EABF parameters can be computed utilizing the values of μm [2]
Summary
Due to the great importance of inorganic scintillator materials in the field of ionizing nuclear radiation detection, they are a very suitable to utilize in many applications such as technology of space, the design of nuclear devices, and medicinal diagnostics [1]. When the gamma ray interacts with the material, the half-value layer (HVL), mean free path (MFP), effective atomic number (Zeff), effective electron density (Nel), exposure buildup factors (EBF), and gamma ray energy absorption (EABF) are the fundamental quantities required to explain the penetration of nuclear radiation in matter. Precise μm values are wanted to provide fundamental results in many nuclear radiation fields like computerized tomography, radiation shielding, nuclear radiation dosimeter, fluorescence of gamma ray, and safety inspection [3]. Journal of Spectroscopy interaction with GAGOC and CMO scintillator materials, μm, HVL, MFP, Zeff, Nel, EBF, and EABF have been investigated in a broad energy range. The values have been computed for μm, HVL, MFP, Zeff, and Nel in the energy range 1 keV–100 GeV and for EBF and EABF in the energy range 0.015–15 MeV using the WinXCom program. The macroscopic fast neutron removal cross section ∑R has been calculated
