INVESTIGATION OF THE RADIATION PERMEABILITY PROPERTIES OF BISMUTH COMPOSITE AND Pb ELEMENT CHARACTERISTIC AGAINST X-RAY
 
X-rays, which are in the group of ionizing radiation (gamma, beta, alpha, etc.), are used primarily in hospitals (diagnosis and treatment), airports, train stations, shopping centers (detection of weapons and dangerous substances), age determination of minerals and historical remains, and It is used more and more in many different application areas day by day. X-rays are radiation with low wavelength, high energy and high penetration value. For this reason, radiation shielding is an increasingly important issue. The characteristic X-ray shielding properties of the Pb element in the 8.91x10-3 MeV-15 MeV energy range and the 95% Bi+5% ZrSiO4 composite material were analyzed in the PSD program. The investigated parameters are mass attenuation coefficient (MAC), linear attenuation coefficient (LAC), tenth value layer (TVL), half value layer (HVL), mean free path (MFP). The designed ZrSiO4 reinforced composite material has approximately 15.6% less density than the Pb element. Although Pb element achieved better results than 95%Bi+5%ZrSiO4 composite material in the study, it can be preferred because Pb is lighter and non-toxic in low-energy radiation applications. Bismuth composite can be used instead of Pb element due to low-energy radiation applications in imaging instruments used in the diagnosis of diseases in medicine.
