“…This risk is much lower than the limit 8.4 × 10 −3 , if the total natural radiation dose of 2.4 mSv/y as given by UNSCEAR 2000UNSCEAR (2000. Th average value (0.16 Bq•L −1 ) is almost matched with Saudi Arabia (Alseroury et al, 2018), higher than Jordan (Al-Shboul et al, 2017) and lower than other countries. The present results show that the average of 40 K concentration is nearly matching the value of Nigeria (Ajayi & Owolabi, 2007), higher than Yemen (Abdurabu et al, 2016) and Jordan (Al-Shboul et al, 2017), while it is lower than the other observed values.…”

Twenty samples of ground water were collected from different wells in Al-Baha region which is located at south-east of Saudi Arabia. Gamma spectrometer based on HPGe crystal was applied to determine activity concentrations in Bq•L −1 of the natural radio nuclides: Radium-226 and Thorium-232 series also Potassium-40. The measured results indicate that the average concentrations of 226 Ra, 232 Th and 40 K in the studied samples were 0.85, 0.43, and 2.84 Bq•L −1 , respectively. The average annual estimated effective dose was found to be 0.058 mSv/y which is lower than the annual limit of the dose allowed by WHO Thus, it has no harmful effects on health.

“…For this reason, the metals and natural radioactivity concentration in water have been studied by many investigators in several countries (Ali et al, 2016;Radulescu et al, 2017;Ghaderpoori et al, 2018;Parhoudeh et al, 2019). In Saudi Arabia, there are limited studies on drinking water (Al-Ghamdi, 2014;Al-Zahrani, 2016;Althoyaib & El-Taher, 2016;Alseroury et al, 2018). According to our literature survey conducted by the researcher, there are no data found on the quality of schools' drinking water supplies in the city of Jeddah.…”

Measurement of natural radioactivity levels of major and heavy metals concentration was carried out for water samples collected from primary schools in Jeddah city, Saudi Arabia. The estimations were done for two different age groups, children (students 7-12 y) and adults (teachers and workers > 17 y) at the schools. The chemical analysis was performed by an Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) and a high-resolution HPGe detector was used for the natural radionuclides measurement. The obtained results for the heavy metals (Fe, Cu, and Zn) and major and heavy elements (Na, K, Ca and Mg) concentrations in all water samples did not exceed the limits of WHO, EPA and TSE-266 guidelines for drinking water. Only Pb exceeded the safe limit. Generally, heavy metals and major elements' concentrations in water samples were found decrease in sequence of Ca > Na > Mg > K > Zn > Pb > Cu > Fe. The radioactivity concentrations of 226 Ra, 232 Th and 40 K in all studied samples were below the permissible safe limit value. The total average annual effective doses of (226 Ra + 232 Th + 40 K) radionuclides were 0.259 mSv•y −1 for the children and 0.112 mSv•y −1 for adults, which are below the recommended annual dose level 1.0 mSv•y −1 as reported by WHO (2006). The present drinking waters are high quality waters and safe in terms of natural radioactivity and the results of the HQ values for the individual heavy metals showed that there was no health risk for humans due to consumption of these waters.

“…These elements are found at trace levels in most exposed and unexposed ground formations. These natural radioactivity elements could dissolve in groundwater with different concentrations due to the Rock/water interactions [7]. Numerous studies have attempted to explain how to determine the natural radioactivity concentrations in groundwater [8][9][10].…”

The Nubian sandstone aquifer's hydrogeophysical and natural radioactivity parameters at the Northwestern part of El Ain village, Sharq El Oweinat, Southwestern desert, Egypt are resolved using geophysical well logging and natural radioactivity techniques. The study aims to monitor the phenomenon of appearing an unusual high gamma-ray at a zone of high resistivity record. A nest of well logs is collected to assess how the phenomenon is widespread. Results of correlated well logs are clarified that this phenomenon at zone between 80 and 100 m and zone of 200 and 230m depth is noticed. The petro-physical properties are estimated from the recorded well logs. The results showed that the percentage of the average of effective porosity % varies between 20 and 28.2%, while average vary from 2 to 12.5 %, which indicates that the aquifer of Nubian Sandstone is classified as a clean aquifer. The natural radioactivities of the studied area in the rock samples were evaluated using high-purity germanium (HPGe) detector. The results indicated that the average value of Th-232 is (51.32 ±4.92%) Bq/kg, Ra-226 is (29.03 ± 4.68%) Bq/kg while the radioactivity concentration of K-40 exists only in one sample with low concentration.
