“…The 222 Rn level was found very high in some river water, such as the 222 Rn level (60 Bq/L) in the Rajouri of Pir Panjal, Kashmir was high due to the mountainous area where many minerals were found in the soil of that region [ 36 ]. The study at Ekiti, Nigeria, claimed that the high 222 Rn level (42–88 Bq/L) was found in river water due to the local geology covered with migmatite, porphyritic granite, granite gneiss, and undifferentiated schist [ 3 ]. In another study, the authors claimed the Gold and Bismuth mining site near the study area in Edu LGA, Kwara State, Nigeria, was the main reason for the high 222 Rn level (19.14 ± 3.98 Bq/L) [ 37 ].…”

“…Therefore, by using Eqs (1) and ( 2), the annual effective dose due to 222 Rn inhalation and ingestion is calculated from the experimentally measured values of the 222 Rn concentration [1,2,5,7]. The total annual effective dose is calculated by using Eq (3).…”

“…Due to its high mobility, 222 Rn gas can swiftly travel from soil and rocks to water and air. Albeit, the concentration of 222 Rn in water depends on the temperature, lithology, geology, rainfall, and earthquake activities [ 3 ]. 222 Rn is highly volatile, easily dissolved, and escapes from the water.…”

“…222 Rn is highly volatile, easily dissolved, and escapes from the water. A relatively higher concentration of 222 Rn is found in groundwater than in surface water due to the aeration process [ 3 ]. Because of its gaseous nature, 222 Rn is used as a tectonic tracer [ 4 ] to determine the tectonic fault lines and predict earthquakes.…”

“…Numerous studies have been performed worldwide to measure the 222 Rn level in various water resources such as tap water, river water, deep well water, bore well water, bottled water, etc. [ 1 , 3 , 7 , 11 , 12 ]. Several advanced countries have a national reference limit of radon in water and indoor air to ensure radiological safety for public health.…”

Radon (222Rn), an inert gas, is considered a silent killer due to its carcinogenic characteristics. Dhaka city is situated on the banks of the Buriganga River, which is regarded as the lifeline of Dhaka city because it serves as a significant source of the city’s water supply for domestic and industrial purposes. Thirty water samples (10 tap water from Dhaka city and 20 surface samples from the Buriganga River) were collected and analyzed using a RAD H2O accessory for 222Rn concentration. The average 222Rn concentration in tap and river water was 1.54 ± 0.38 Bq/L and 0.68 ± 0.29 Bq/L, respectively. All the values were found below the maximum contamination limit (MCL) of 11.1 Bq/L set by the USEPA, the WHO-recommended safe limit of 100 Bq/L, and the UNSCEAR suggested range of 4–40 Bq/L. The mean values of the total annual effective doses due to inhalation and ingestion were calculated to be 9.77 μSv/y and 4.29 μSv/y for tap water and river water, respectively. Although all these values were well below the permissible limit of 100 μSv/y proposed by WHO, they cannot be neglected because of the hazardous nature of 222Rn, especially considering their entry to the human body via inhalation and ingestion pathways. The obtained data may serve as a reference for future 222Rn-related works.

This research investigates the geophysical, hydrogeochemical, and geological characteristics of the Nubian Aquifer System in the El-Marashda area, located beneath the Eastern Sahara Desert in northeastern Africa. The primary objective is identifying the aquifer geometry, assessing groundwater quality, and evaluating environmental pollution levels. A Magnetotelluric survey was employed to examine the subsurface geological composition and electrical resistivity characteristics of the aquifer system. The study revealed a freshwater-saturated Nubian Sandstone layer at depths between 986 and 1009 m with resistivity values of 101 to 182 Ohm.m, indicating a substantial and potentially sustainable groundwater resource. Overlying limestone and Marly Limestone layers influence the aquifer’s permeability and storage capacity. The chemical analysis of water from three wells showed suitability for drinking and irrigation, with no sodium and magnesium levels hazards. The Heavy Metal Pollution Index (HPI) and Heavy Metal Evaluation Index (HEI) indicated low to medium contamination, posing potential environmental health risks. Human health risk assessments using USEPA methodology found acceptable non-carcinogenic risks, with Hazard Quotients (HQs) for heavy metals below 1 and a negligible Hazard Index (HI). The comprehensive investigation underscores the potential for sustainable groundwater utilization in El-Marashda. It highlights the aquifer’s suitability for irrigation, with low contamination levels and minimal health risks. These findings provide a foundation for informed and sustainable water resource management, environmental protection, and resilient infrastructure development in the region. The methodologies and results align with global standards, demonstrating their applicability in globally diverse geological contexts. This research contributes valuable baseline data for future studies and monitoring efforts, whether at local or global sites, emphasizing the importance of continued investigation to ensure sustainable groundwater management.
