This article reports the results of an investigation into the activity concentration of natural radionuclides in raw building materials for underground parking lots, together with the assessment of the radiation hazard for the public related to exposure to ionizing radiations. To this purpose, high-purity germanium (HPGe) γ-ray spectrometry was employed in order to quantify the average specific activity of 226 Ra, 232 Th, and 40 K natural radioisotopes. With the aim to assess any possible radiological health risk for the population, the absorbed γ-dose rate ( D ), the annual effective dose equivalent outdoor ( AEDEout ) and indoor ( AEDEin ), the activity concentration index ( I ), and the alpha index ( Iα ) were also estimated, resulting in values that were lower than the maximum recommended ones for humans...
