Background: Inspection of the level of radioactivity from radionuclides in soil is important for the assessment of the exposure to natural radiation. Materials and Methods: Ten samples from soil were collected from different sites of Kirkuk-IRAQ and the level of natural radioactivity was measured using gamma-ray spectrometry based on a high purity germanium (HPGe) detector. Results: It was foun...

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 b...

Introduction: Although travertine is now widely used as a building material, the effects of its radiological hazards to public health should be a matter of concern. Therefore, this study aimed to determine its radiological parameters with regard to human health. Material and Methods: In this research 10 travertine samples were collected ...
