“…The concentrations of natural radionuclides in building raw materials (e.g., cement, bricks, concrete) are also measured to establish dose criteria [4][5][6]. In this regard, plenty of radioactivity measurements in magmatic rocks and in building raw materials from different localities of Turkey have been researched and reported by several workers [1][2][3][7][8][9][10][11][12][13][14][15][16]. From the natural radioactivity assessments in construction materials in Elazığ, Turkey [11], highest radiation value obtained in gas concrete (as 405.2 Bq/kg), which is higher than global values (370 Bq/kg).…”

Available natural radioactivity (40 K, 238 U, 232 Th) measurements on Plio-Quaternary volcanic and pyroclastic rocks, which are usually used as building raw materials, from the Isparta region of SW Turkey, released that their radium equivalent activity values are close to the internationally accepted upper limits and a potential radiation risk. In this study, the relationship between their magma and source characteristics has been investigated to reveal the reason of the high radiation values in these volcanic materials carrying value by more than three times the equivalent materials in Turkey. Recent volcanological studies have shown that potassic-ultrapotassic magmas governed the genesis of the Isparta volcanism. Potassium-rich characters and elevated concentrations of radiogenic (e.g.,Th and U) and total rare earth elements (∑REE) are their most diagnostic features. These characteristics are also similar to some mantle-derived carbonatites (e.g., Norwage and Kenya) with high radiation levels. To support this, recent investigations also revealed that the origin of Isparta potassic volcanism is associated with a common and enriched mantle source, which were interacted with carbonatite melts. Accordingly, carbonatitic melts left their geochemical imprints into their mantle sources, and partial melting of this mantle source produced K, REE, Th, and U-rich volcanic materials with high radiation levels in the region. These results indicate that the carbonatite-influenced mantle source were played a key role for not only enrichments in distinct elements (e.g., Th, U and REE) but also high radioactivity levels in Isparta volcanic and pyroclastic rocks. In this study, attention is drawn to the fact that a potential risk of high radiation in volcanic and pyroclastic rocks used as building raw materials can be expected for a given volcanic region, which include potassic magma derived from a carbonatitemodified mantle source.

“…Up until now, several studies on the radiometric, petrographic and mineralogical properties of natural stone samples have been reported (Anjos et al, 2005;Xinwei et al, 2006;El-Arabi, 2007;Asghar et al, 2008;Kitto et al, 2009;Koornneef et al, 2010;Lanzo et al, 2010;Moura et al, 2011;Abd El-Ghafour et al, 2012;Capaccioni et al, 2012;Trevisi et al, 2012;Turhan, 2012). However, according to our literature survey, a comprehensive study related to the radiometric properties of volcanic tuff samples collected from Turkey has not yet been conducted, except one study in which eight volcanic tuff samples were considered (Degerlier, 2013). In this study, a total of 76 volcanic tuff stones collected from different quarries located in four geographical regions of Turkey were analyzed using gamma-ray spectrometry to determine the activity concentration of 238 U, 232 Th, 226 Ra and 40 K, and the emanation Yellow (1), cherry (1), black (1), white (1), red (1), turquoise 1N e v sehir-Ürgüp (Central Anatolia) Q10 5 Yellow (1), cherry (1), dusty-rose (1), light brown (1), black (1) Nevşehir-Avanos road (Central Anatolia) Q11 4 Yellow-white (1), white (1), dark yellow (1), Cappadocia rose (1) N e vşehir-Aksaray road (Central Anatolia) Q12…”

Radiometric analysis of volcanic tuff stones used as ornamental and structural building materials in Turkey and evaluation of radiological risk

Volcanic tuff stones are widely used to coat the interior and exterior surfaces of buildings for ornamental purposes in the construction industry in Turkey, and are also used as structural material in the construction of masonry buildings, especially in the Cappadocia region, which is a popular tourist destination. In this study, seventy-six volcanic tuff stone samples collected from different quarries located in different geographical regions in Turkey were surveyed for radiometric analysis, and the radiological risk to human health caused by ionizing radiation from natural radionuclides in the volcanic tuff stone samples was evaluated. The activity concentrations of 238 U, 232 Th, 226 Ra and 40 K analyzed in volcanic tuff stone samples were very variable, ranging from 3 to 389, 8 to 401, 2 to 263 and 99 to 2107 Bq kg −1 , respectively. The emanation coefficient and mass exhalation rate of 222 Rn measured for the volcanic tuff samples ranged from 2 to 68% with an average of 34%, and 1 to 194 μBq kg −1 s −1 with an average of 43 μBq kg −1 s −1 , respectively. The external (gamma) and internal (alpha) hazard indices, indoor absorbed gamma dose rate and the corresponding annual effective dose were estimated to evaluate the potential radiological risk to human health. The results showed that all of the surveyed volcanic tuff stone samples can be used as covering building materials for ornamental or insulating covering purposes. However, the use of some volcanic tuff stone samples as structural building materials should be restricted.
