Description

Natural radioactivity was measured in Bunair Granite using high purity germanium gamma-ray spectrometer and compared to world's granites and building materials to access its suitability for the construction purpose. Average gamma-activities of 226Ra, 232Th and 40K were found to be 52.41, 58.41 and 1130.12 Bq kg-1, respectively. The Indoor and outdoor radiation indices including excessive life-time cancer risk (ELCR) were calculated. The average indoor ELCR was estimated as 3.49 x 10-3. The average outdoor ELCR was assessed as 0.46 x 10-3. As a basic building material Bunair Granite should be on low propriety. For flooring, facing the buildings and as Table tops, in kitchens and other utilities it is safe. (authors)
