Radiation absorption properties of some metals used as biomaterials

Abstract

The aim of the study is to evaluate some basic gamma-ray attenuation properties of various types of biomaterials used in the human body as synthetic or natural materials. GAMOS 6.2 is used to compute the Linear Attenuation Coefficient (LAC). Other critical parameters Half Value Layer (HVL), Tenth Value Layer TVL, and Mean Free Path (MPF) are determined as well. During the computational phase of the study, a mono-energetic point photon source geometry with energies ranging from 1 keV to 20 MeV is used by directing a parallel photon beam toward the absorber material using Monte Carlo software. Radiation shielding properties are measured in the experiment section of the study at 662, 1173, and 1332 keV. M3 has the best values for the investigated parameters. Furthermore, metal biomaterial M3 with Cr, Mn, Fe, Co, and Mo elements and 8.4 g/cm3 density has the lowest HVL, TVL, and MPF values. According to our findings, M3 has exceptional gamma-ray attenuation properties in metal biomaterials. The Monte Carlo method is shown to be a viable option for calculating mass absorption coefficients at the desired gamma energy, especially for samples that are physically demanding to generate.
