“…Samples of volume 5 mL were analysed for radioactivity levels using a Hyper-Pure Germanium detector (HPGe) gamma spectrometer, p-type crystal; Genie 2000 Basic Spectroscopy Software (Canberra, USA) was used for data acquisition, display and analysis. The relative efficiency of the detector was 25% and the full width at half maximum (FWHM) at 1461 keV was 4.2 keV (Rajeshwari et al, 2014;Raghu et al, 2015;Shittu et al, 2015). The lowest limits of detection were determined to be 0.30±0.06, 0.26±0.04 and 1.71±0.05 Bq kg -1 for 226 Ra, 232 Th, and 40 K, respectively.…”

Fifteen iron ore samples collected from Wadi Sawawin, Duba, Saudi Arabia were analysed using X-ray diffraction in order to determine mineral composition. Atomic absorption analysis was used to determine concentrations of Al, Ca, Fe, K, Mg, Bi, Pb, Th and U. Natural radioactivity concentrations were determined using gamma-ray spectrometry based on a hyper pure germanium (HPGe) detector; concentrations ranged from 1.89±0.39 to 4.50±0.53 Bq kg -1 , 1.21±0.16 to 3.60±0.56 Bq kg -1 and detection level to 10.33±1.32 Bq kg -1 for 226 Ra, 232Th and 40 K, respectively. In order to assess the potential radiological risks to human health, the absorbed dose rate, radium equivalent activity, annual absorbed dose and external hazards were determined and compared to limits recommended by UNSCEAR. Results were within recommended safe ranges, meaning that the area under study is radiologically safe for habitation and that local iron ores are radiologically safe to be used as construction materials.

In this study, the levels of natural and anthropogenic radioactivity in the sediment samples, collected from Beni Haroun Dam, were investigated using gamma-ray spectrometry. The results obtained for the 238 U, 232 Th series, 40 K natural element and 137 Cs anthropogenic radionuclide are discussed. To evaluate the radiological hazard of radioactivity in samples, the absorbed dose rate, the annual effective dose, the radium equivalent activity Raeq, the external and internal hazard indices Hex and Hin were calculated and presented in comparison with the data collected from different areas in the world.

“…Determination of the activity concentrations of the terrestrial and fallout radionuclides are of a great interest for many researchers. In the recent past many studies were published in the literature (Kurnaz et al 2011;Hannan et al 2012;Khan et al 2012;Tufail et al 2013;Dhawal et al 2013;Kunovska et al 2013;Manohar et al 2013;Santawamaitre et al 2014;Sivakumar 2104;Dusane et al 2014;Miller and Voutchkov 2014;Ajmal et al 2014;Rajeshwari et al 2014;Bakım and Görgün 2015;Srilatha et al 2015;Kurnaz 2016;Altıkulaç et al 2016). To date, there has been no survey reported on the background radiation levels in Zile (Tokat) region, which is famous with grape molasses in Turkey (Zile molasses).…”

The activity concentrations of radionuclides in grape molasses soil samples collected from Zile (Tokat) plain in Central Black Sea region of Turkey were measured by using gamma spectrometer with a NaI(Tl) detector. Also, the concentrations of 222 Rn in soil samples and air were estimated essentially taking the activity concentrations of 226 Ra measured in soil samples. Grape molasses soil samples with calcium carbonate content are used for sedimentation for making molasses in this region. The average activity concentrations of 232 Th, 226 Ra, 40 K and 137 Cs were found as 62 ± 2, 68 ± 3, 479 ± 35 and 8.0 ± 0.3 Bq kg -1 , respectively. The average concentrations of 222 Rn in soil samples and air were estimated to be 50 kBq m -3 and 144 Bq m -3 . From the activity concentrations, absorbed gamma dose rate in outdoor air (D), annual effective dose from external exposure (E E ), annual effective dose from inhalation of radon (E I ) and excess Downloaded by [Dalhousie University] at 11:28 05 June 2016 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 lifetime cancer risk (ELCR) were estimated in order to assess radiological risks. The averagevalues of D, E E , E I and ELCR were found to be 90 nGy h -1 , 110 Sv y -1 , 1360 Sv y -1 and 4 x 10 -4 , respectively.
