Measurements of radioactivity and dose assessments in some building materials in Bitlis, Turkey

Characteristics and properties of Bitlis ignimbrites and their environmental implications

“…Dry unit volume weight, wet unit weight, water absorption percentage, thermal conductivity coefficient, specific heat, pressure and tensile strength were determined by standard tests. In addition to physical and chemical properties of building materials, determination of radiological parameters such as mass attenuation coefficient, gamma and radon gas emission is important for human health (12)(13)(14). In this study, the mass attenuation coefficient, gamma radioisotope concentration and radon gas emission of Bitlis stone were determined by using nuclear methods.…”

Peer Review #1 of "Radon and thoron exhalation rate, emanation factor and radioactivity risks of building materials of the Iberian Peninsula (v0.1)"

“…These factors lead to a complicated thoron measurement technique resulting in, the majority of the existing studies focus on the radon [2][3][4][5][6][7][8][9][10][11][12]. Many of these studies also include measures of 40 K, 226 Ra and 232 Th and risk indexes definitions trying to evaluate the radiological health hazards of these radionuclides (Turhan & Gündüz, 2008;De With, De Jong & Röttger, 2014;Kumar et al, 2015;Kayakökü, Karatepe & Doğru, 2016;Madruga et al, 2018) or the effective dose due to radon and its progeny (Sabiha-Javied, Tufail & Asghar, 2010).…”

Geological Materials as Sources of Rn Emissions

“…The consulted publications presented results of mass exhalation rates or surface exhalation rates or both (few publications) from diverse types of rocks. Granites are the rock type most frequently considered (Allen et al [3]; Chauhan [4]; Marocchi et al [5]; Moura et al [6]; Pereira et al [7,8]; Bavarnegin et al [9]; Pereira et al [10]; Rafique & Rathore [11]; Guillén et al [12]; Marques et al [13]; Andrade et al [14]), but there are also studies that include other igneous rocks (Chauhan [4]; Marocchi et al [5]; Moura et al [6]; Pereira Gómez et al [7]; Rafique & Rathore [11]; Guillén et al [12]), with a predominance of pyroclastic rocks (studied in Marocchi et al [5] ]; Andrade et al [14]; Turhan et al [15]; Kayakökü et al [16]. There are some studies with results on metamorphic rocks such as marbles (Bavarnegin et al [9]; Rafique & Rathore [11]; Andrade et al [14]) and silicate metamorphic rocks (Chauhan [4]; Marocchi et al [5]; Pereira et al [10]; Andrade et al [14]), and also some studies that include information in sedimentary rocks being (Bavarnegin et al [9]; Pereira et al [10]; Andrade et al [14]).…”
