Abstract

Abstract: In this work, were determined some radiation shielding and dosimetric parameters of three types of bricks for photons energy from 1 keV to 100 GeV photons using the Phy-X/PSD software, and for comparison also has been calculated the same parameters for NBS concrete. The parameters calculated are the linear attenuation coefficients (LAC), effective atomic numbers (Zeff), half value layers (HVL), the energy absorption buildup factors (EABF) and the exposure buildup factors (EBF), as well as the coefficients to use the geometric progression (G-P) fitting method. Obtained results show that the three types of bricks can be used safely for the design of medical facilities housing mammography units (less than 30 keV). Highlights: The radiation shielding and dosimetric parameters of three types of bricks were determined using the Phy-X/PSD. The parameters calculated are (LAC), (Zeff), (HVL), (EABF) and (EBF). For comparison also has been calculated the same parameters for NBS concrete. For low energy photons, artisanal bricks have good shielding performance.
