 In this paper, the authors conducted a study on the natural and anthropogenic radioactivity and heavy metal content in a basalt aggregate, used for concrete from Sicily, Italy. The specific activities of radium-226, thorium-232, potassium-40, and cesium-137 were measured using gamma-ray spectroscopy. Additionally, the authors calculated various indices to assess the radiological risk associated with radiation exposure, including the alpha-index, i-alpha, the radium-equivalent activity, rake, the absorbed gamma-dose rate, d, and the annual effective dose equivalent outdoors, AED-eat, and indoors, AED-ine. Measurements of the average heavy metal concentrations in the basalt aggregate were also taken using inductively coupled, plasma-mass spectrometry, ICPMS. To identify the sources of the radioactive elements, the authors used x-ray diffraction, XRD, to determine the major mineralogical phases present in the basalt aggregate.
