Background: This study aimed to investigate the radiation hazard indices from sand samples of Ma'rib Governorate in Yemen, where the majority of oil and gas facilities are installed. Methods and Materials: Thirty five samples of desert sand from Ma'rib Governorate in Yemen were collected and tested their radiation hazard indices by using High Purity Germanium (HPGe) detector. Results: Based on the measurement of the concentrations of 226 Ra, 232 Th, and 40 K, the radium equivalent activity (Ra eq ), the activity concentration index , the external hazard index (H ex ) and the internal hazard index (H in ) were all calculated. Also, the absorbed dose rate in Air (ADR) and the annual effective dose (AED) are calculated. Conclusions: Comparing the practically attained results with internationally permissible values, it was found that most of the radiological parameters, including the radiation hazard indices of the studied samples, fall within the world's permissible limits and don't expose risks to the human beings and environments.

“…IAEA RGU-1, RGTh-1, and RGK-1 standards were used for the quality controls and activity calculations (Table 1). Detailed information about the measurement system is provided by [40,41]. All samples were counted for 50,000 s. Background intensities were also obtained under the same conditions before and after the measurements of the samples.…”

The study aimed to determine the natural radioactivity levels of 226Ra, 232Th, and 40K by the Gamma-Ray spectrometry method, and radiological hazard parameters of the plutonic rocks in the Western and Central Sakarya Zone and to analyze the data using multivariate statistical methods. The average radiological values of samples were determined as 40K (1295.3 Bq kg−1) > 232Th (132.1 Bq kg−1) > 226Ra (119.7 Bq kg−1). According to the skewness values of the distributions of the examined radionuclides, 226Ra (2.1) and 232Th (0.7) seemed to be positively right-skewed while 40K (−0.2) had a negatively right-skewed histogram. On the other hand, the following kurtosis values were calculated for the distributions: 226Ra (5.8 > 3), 232Th (−0.7), and 40K (−0.8). Kolmogorov–Smirnov and Shapiro–Wilk tests were applied to the data to test their normality. Therefore, Spearman’s correlation coefficient method was performed. The radionuclides of 226Ra and 232Th were found to have a positive correlation with radiological hazard parameters of the samples. 2 (two)-related factors identified, and the cumulative value was calculated to be 98.7% on the basis of the Scree Plot. According to the hierarchical cluster analysis, the samples that are grouped with those from Camlik region are prominent. The average radioactivity values of Camlik, Sogukpinar, Karacabey, and Sogut (except for 232Th) regions were detected to be higher than the world averages while the value of 40K was also found to be higher than the average values of various countries in the world.

The determination of radiation level is important in living areas for human health. The aim of this study is to determine environmental radiation in the beach sands of Tatvan, Ahlat and Adilcevaz. Environmental gamma radiation and alpha-beta concentrations determined for 15 different points. It has used portable gamma survey meter which is NaI(TI) scintillation detector. It has also used portable alpha-beta survey meter which consist of ZnS(Ag) scintillator adhered to 0.25 cm (0.010 in) thick plastic scintillator. For α/β emission measurements mean value was measured 81.2 cpm. The mean gamma dose rate value was measured as 0.149 µSv/h for ground level and 0.130 µSv/h for 1 m above the ground. The annual effective dose equivalent was obtained as 261.0 µSv/y. The obtained results were compared with literature.
