Evaluation of Environmental Radioactivity and Hazard Impacts Saudi Arabia Granitic Rocks Used as Building Materials

People use granite in residential buildings on a large scale all around the world. Knowing granite’s radiological characteristics allows for safe of its properties to be maintained over time. Our findings are significant two reasons: first, they may increase public awareness naturally radioactive materials under investigation, and second, necessary establish standards, regulations, management building used Saudi Arabia. In this study, twenty-four granitic rock samples were collected from Hai’l area Arabia, these as material. Gamma spectrometry was measure amounts 238U, 232Th, 226Ra, 40K samples. The obtained data also calculate some environmental hazard parameters, such absorbed gamma dose rate (AGDR), annual effective (AEDR), radium equivalent (Raeq), external internal indexes (Hex Hin), index (Iγ), alpha (Iα), excess lifetime cancer (ELCR). We concluded that harmful need more attenuation if materials.
