“…More than half of the analyzed samples contain activity concentrations of 226 Ra higher than 150 Bq/kg and of 228 Ac higher than 250 Bq/kg. These are significantly higher than the average activity concentrations in granite samples (Pavlidou et al, 2006;Righi and Bruzzi, 2006) while similar to those reported by Marocchi et al (2011) for volcanic rocks like trachyte, tephriphonolite, etc. Similar U and lower Th contents were also reported by Gomes et al (2011).…”

“…3 concentrations of U are reported against Th for all the samples analyzed. U and Th concentrations for basaltic lavas and rhyolitic obsidians pertaining to Iceland and Aeolian islands (Italy), granites, trachites, rhyolites and high grade metamorphic rocks (Pavlidou et al, 2006;Marocchi et al, 2011) are also reported. Volcanic rocks from Iceland show the lowest concentration of U and Th with rhyolitic obsidians significantly enriched with respect to basaltic lavas.…”

“…3. Correlation between the concentrations of U and Th measured by gamma spectrometry in samples from Vulsini Volcanic District, rhyolitic obsidians from Iceland* and Aeolian* Islands (*unpublished data), granites from different origin (after Pavlidou et al, 2006), trachites, rhyolites and granites from different origin (after Marocchi et al, 2011). The lifetime risk of lung cancer due to radon inhalation and the cancer risk from the other pathways have been estimated also for the simulated standard rooms (Table 5).…”

“…Uranium and thorium are primarily associated with heavy minerals such as monazite, zircon, and allanite, and secondarily associated with apatite and titanite. This is also reported by Marocchi et al (2011) [38]. Allanites, monazites and zircons preferentially incorporate the radioactive elements Th and U, as minor elements [39] as well as REE, especially LREE.…”

This study aims to evaluate the activity concentrations of 238 U, 226 Ra, 232 Th, 228 Th and 40 K along the beaches of Kavala being adjacent to the rock-types of the Kavala pluton. These ranged from 14-940, 16-1710, 26-4547, 27-4488 and 194-1307 Bq/kg respectively, representing the highest values of natural radioactivity measured in sediments of Greece. The (%wt.) heavy magnetic (HM) (allanite, amphibole, mica, clinopyroxene, magnetite and hematite) fraction, the heavy non-magnetic (HNM) (monazite, zircon, titanite and apatite) fraction and the total heavy fraction (TH), were correlated with the concentrations of the measured radionuclides in the bulk samples. for local people working on the beach.

IntroductionAll varieties of building materials, including various naturally occurring as well as artificial materials, have varying concentrations of Ra, Th, and K and can cause direct radiation exposure to human beings. Granite, as a market term, includes a wide variety of rock types including plutonic, volcanic, and metamorphic rocks. Granite's durability and appearance make it a popular building material in dwellings. These rocks can contain various amounts of minerals with high Ra, Th, and K concentrations such as zircon, monazite, xenotime, allanite, epidote, or K-feldspars.According to the European Commission (1999), radioactive doses should comply with the ALARA ("as low as reasonably achievable") radioprotection principle. The average annual effective equivalent should be limited to 1.6 mSv. Materials such as granites, potentially containing high concentrations of natural radionuclides, should be studied in order to control the exposure levels for human beings. The limit of 1.6 mSv per year is widely accepted by many international organisations such as the International Commission on Radiological Protection (ICRP), the World Health Organization (WHO), and the European Commission.Natural radionuclides increase both the external (γ-rays) and internal (α-rays) radiation to human beings. 238 U, 232 Th, and 40 K are the main contributors of γ-rays, while α-rays are principally emitted by radon, a decay product of 238 U radioactive series. The Rn isotopes are responsible for roughly half of the radioactive dose exposure from natural sources. Moreover, Rn isotopes are considered as an important cause of lung cancer (UNSCEAR, 2000; WHO, 2009). Many investigations on the radioactivity levels of granitic rocks, used or potentially used as decorative and building materials, can be found in the recent literature
