Natural radioactivity levels and related risk assessment in soil samples from Sakarya, Turkey

Measurement of natural radioactivity and radiological hazard evaluation in the soil samples collected from Owo, Ondo State, Nigeria

“…The study of radiological characteristics of the soil samples using Shapiro-Wilk's test (p > 0.05) and visual inspection of their histograms (Figure 2) show that the activity concentrations of 40 K, 232 Ra is not normally distributed by considering the same test as described above; it is evident that the distribution is positively skewed with a skewness of 2.764 (SE = 0.309) and a kurtosis of 11.959 (SE = 0.608), and it thus follows a lognormal distribution. This is also confirmed as the values of the geometric mean (60.38) and the median (58.58) are almost the same (Tabar et al, 2017). The test was carried out on the radiological indices, and they follow the same trend.…”

“…A comparison of the average values of the activity concentrations in this study (that is, 1190.10 BqKg −1 for 40 K, 64.64 BqKg −1 for 226 Ra, and 110.18 Bqkg −1 for 232 Th) with the corresponding average values from the results reported in Nigeria, Egypt, Malaysia, India, Turkey, and Iraq (Ajayi, 2009;Ademola, Bello, & Adejumobi, 2014;El-Gamal, Farid, Abdel Mageed, Hasabelnaby, & Hassanien, 2013;Issa, 2013;Kolo et al, 2015;Mohammed & Ahmed, 2017;Srilatha et al, 2015;Tabar et al, 2017;Zaim & Atlas, 2016) indicates that the values measured in this study are relatively higher. Meanwhile, the reported values in this study are less than the values reported in Cyprus and Turkey (Merdanoǧlu & Altinsoy, 2006;Tzortzis, Svoukis, & Tsertos, 2004).…”

“…Results show that the values calculated are in the range of 111.27-500.66 Bqkg −1 with an average value of 311.20 Bqkg −1 . The average value is observed to be higher than 205.47 Bqkg −1 for India, 135 Bqkg −1 for Egypt, 126 Bqkg −1 for Thailand, 64.14 Bq kg −1 for Turkey, and 24.92 Bq kg −1 for Malaysia (Issa, 2013;Kolo et al, 2015;Kritsananuwat et al, 2015;Srilatha et al, 2015;Tabar et al, 2017). However, the average value is less than 370 Bq kg −1 , the criterion limit suggested by Beretka & Matthew (1985).…”

Characterization of radionuclide activity concentrations and lifetime cancer risk due to particulate matter in the Singrauli Coalfield, India

“…Chernobyl and Fukushima released radioactivity producing worldwide radionuclide contamination in addition to the nuclear weapons testing in the atmosphere upto 1963 and from some subsequent venting of underground tests (Han and Park 2018;Jia et al 2005). Greater than half of total radioactive dose is associated with inhaled radioactivity associated with airborne particulate matter of different sizes (Sahin et al 2017;Tabar et al 2017).…”

Assessment of Background Radiation Levels and Associated Doses in Soils of the Most Popular Tourist Place Muree, Pakistan

“…137 Cs a fission product with high yield of 85% and half-life of 30 years is a prominent indicator of nuclear releases [2]. The levels of natural radioactivity in soil have been reported by many researchers in mid and southern Rechna interfluvial region [6,7], Lahore [8], district Swat [9], Hunza [10], Mirpur [11], Bahawalpur division [12] of Pakistan and other parts of the World [13][14][15][16][17].…”
