Gamma-Rays Absorption Studies of Garnet series of Gemstones at 1 Kev to 100 GeV: Theoretical Calculation

Abstract

-Mass attenuation coefficients and partial photon interactions have been calculated theoretically at incident photon energy 1 Kev to 100 GeV for garnet series of gemstones (Grosaularite (GS1), Pyrope(GS2), Spessarlite(GS3), Almandine(GS4), Uvarovite(GS5) and Androdite(GS6) using XCOM software [1]. The values of these parameters have been found to change significantly with incident photon energy and composition of the garnet series of gemstones. Half value layer (HVL) and tenth value layer (TVL) has also been calculated; whose lower value reveals the good shielding ability for gamma rays. Hence it is concluded that GS4 shows the maximum shielding effectiveness and also GS6 and GS3 seem to have good radiation shielding. It is also analyzed that our calculated mass attenuation coefficient of NBS concrete by the present method are in excellent agreement with standard values given by ANSI/ANS-6.4.3 data.

A Comprehensive Study of Gamma Ray Interaction Parameters in Dana's Minerals

“…Many researchers have studied linear and mass attenuation coefficients [13][14][15][16] for different energies and our research group [17][18][19][20]have studied interaction parameters for various low-Z composite materials. Also various researcher have studied gamma ray buildup factors of different types of materials such as amino acids, fatty acids and carbohydrates (21), polymers (22), Heavy metal oxide glass (23), which showed that the GP fitting is a very useful method for estimation of exposure and energy absorption build-up factors.…”

“…Furthermore, when the gamma ray interacts with the material, the half-value layer (HVL), mean free path (MFP), effective atomic number (Z eff ), effective electron density (N el ), 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, Z eff , N el , EBF, and EABF parameters can be computed utilizing the values of μ m [2]. Precise μ m 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].…”
