“…40 K in diets from the study in a major mining region of Ghana was the highest contributor (48%) to committed effective dose, followed by 228 Ra (35%), 226 Ra (16%) and 228 Th (1%) respectively [17]. Phosphate rock and phosphogypsum declare higher radiological parameters than the world limit while for phosphoric acid are within the world permissible limits in Phosphate Fertilizers and Chemicals Company, located in Egypt [18]. Therefore, it is essential to assess radioactivity hazards to the population and understand the environmental behavior of natural radionuclides in the different media that surround a mining area.…”

Radioactive levels and radiological hazard assessment associated with exposure to radionuclides from uranium tailings were investigated in this study. Herein, the concentrations of 238 U, 226 Ra, 232 Th, and 40 K in 36 samples including 25 soil and 11 water samples were measured using a low background HPGe semiconductor detector. The radionuclide concentrations were much lower outside the tailings reservoir than inside the reservoir; however, both exceeded the national average and world average values. The mean concentrations of 238 U, 226 Ra, 232 Th, and 40 K in water samples were higher than the WHO guideline levels. The radionuclide transfer factors showed that the radionuclides in soil of the tailings enter the surrounding water. Additionally, the radiological hazard indices around the reservoir were much higher than the worldwide average. Results suggest that the high level of radiation in the tailings reservoir posed a potential threat to the health of the local residents.

“…However, in arid climates during the summertime, the impact of leaching and evaporation probably increases the mobility of these nuclides to the groundwater. Additionally, higher radiogenicity has been declared from the intensive use of phosphate as fertilizer (Neiva et al, 2016 andKorany et al, 2021).…”

roundwater in the Kharga Oasis, located in the Western Desert of Egypt, is an essential resource for the local population. The Oasis is fed by the Nubian Sandstone Aquifer (NSA) of the Cretaceous age. This aquifer is one of the world's largest reservoirs, which provides fresh water for drinking, irrigation, domestic use, and industrial purposes. The NSA possesses four bearing zones; Zone A, Zone B, Zone C, and Zone D, which are separated by clay confining layers. The total penetration depth ranges from 12.5 to 800 meters, and the aquifer is underlain by granitic and basement rocks. The groundwater temperature ranges between 18 to 36.8°C, where high temperatures have been detected in the deeper zones (C and D), indicating geothermal activity. Generally, the quality of NSA water is fresh to brackish water types; however, the deeper aquifer zones (C and D) mainly contain freshwater. The concentrations of the trace elements and the natural radioactive nuclei (Rb, Pb, 232 Th, 238 U, and Sr) in the NSA waters are insignificant and far below the permissible drinking limits, and they are mainly coming from the geogenic source due to leaching of aquifer matrix. The stable isotopes (δ 18 O and δ 2 H) show great insights for recharge and salinization sources. The δ 18 O ranges from -11.96 to -6.11‰, while δ 2 H ranges between -83.5 to -67.7‰, indicating that the groundwater in the NSA is fossil water (paleometeoric origin) as the aquifer was recharged during the paleo heavy pluvial periods. Accordingly, the groundwater in Kharga Oasis is a paleo nonrenewable resource whose quality has been threatened mainly by geogenic natural pollution, agricultural activity, and overexploitation.

“…Recently, some researchers have been carried out and reported on the subject of natural radiation and radiological hazards from chemical fertilisers (El-Bahi et al, 2017;Faweya et al, 2018;Korany et al, 2021;Loan et al, 2018). The objectives of this study were to evaluate natural radioactivity concentration in chemical fertilisers used in the Ahar area, Iran, and calculate radiological risk due to chemical fertilisers using for agriculture purposes.…”

To investigate, the radiological hazards indices of chemical fertilisers commonly used in agriculture soils of Arasbaran, Iran, the activity concentration of 226 Ra, 232 Th and 40 K in four types of chemical fertilisers were measured by gamma spectrometry system. The concentration range for 226 Ra, 232 Th and 40 K were obtained from 54±2.2 to 1585±29.4, 6±0.1 to 157±9.1 and 31±1.5 to 1496 ± 32.8 Bq/kg, respectively. The obtained results showed that the average of radiation hazard parameters for the fertilisers were higher than the reference level for the gamma index(I), alpha index(I), absorbed dose rate(D), and ambient dose equivalent rate (H*( 10)) values. The outcomes give rise to that more parameters values are over the permissible limit, increasing the likelihood of adverse health consequences.
