Abstract

Radiation causes genetic changes in living systems, especially by adversely affecting health of human beings, animals and plants. The need for shielding for protection against radiation still maintains its importance today. In this study, hexagonal boron nitride ceramic material was doped with Ni–Co–B at different current densities and the absorption properties of these samples against alpha, beta and gamma radiation were investigated. It was found from the XRD and SEM images as well as radiation absorption rates that the radiation absorption properties of these samples decreased with the increase in current density. The coalescence level of hBN particles was determined to be 0.68 at a maximum current density of 100 mA/cm2. It was observed that the absorption percentages for each radioactive beam source were between 0.76 and 5.48 at 50 mA and between 0.10 and 1.53 at 150 mA. The results were calculated and compared with the range values of the databases available in the literature, and it was procured that the results were compatible. This study will contribute to studies on shielding for radiation protection.
