“…To evaluate the physical and chemical factors that may affect the source and mobility of HMs concentration in the well water of the study area, the relationship correlation was used to determine correlations between physicochemical parameters and HMs concentration [48]. Pearson correlation is used to determine linear correlations between different parameters and HMs as pairs in drinking water samples.…”

Groundwater is an important source of domestic drinking water supply, and groundwater quality assessment is necessary to reduce pollution to acceptable levels. Therefore, this study aims to determine the concentrations of heavy metals (HM) (Cr, Cd, Cu, Ni, Mn, Fe, and Zn) in the groundwater of Rada'a City and to evaluate the health risk. Groundwater samples were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES). The following average concentrations (mg/l) were determined in the groundwater 0.01035, 0.01702, 0.043718, and 0.03652 for Cu, Ni, Mn, and Zn were concentration values lower than the World Health Organization acceptable limit (WHO) 2, 0,07,0.4, and 4 for Cu, Ni, Mn, and Zn, respectively, but at some locations in the study area, concentration values were found to be above the acceptable limit 0.3 (mg/l) for Fe, the average concentrations were 0.42567 (mg/l). Based on the HM concentrations, the health risk was classified as non-carcinogenic. The health risk indices (HRI) were < 1 for all HMs in the groundwater samples, indicating no health risk. In addition, a high carcinogenic risk (Probability of Cancer Risk, PCR) of 4.42 × 10−4 on average was found from drinking water consumption, while the acceptable range for cancer risk is ≤ 1 × 10−6 to 1 × 10−4.

“…Radioactivity is the process through which nuclei spontaneously emit subatomic particles named radiation. Three main types of radiation are emitted (Abdurabu 2016): (1) α-rays (helium nuclei with two protons and two neutrons), (2) β-rays (electrons), and (3) γ-rays (photons). U and Th are de ned as Natural Occurring Radioactive Materials (NORM) and the parent radionuclides 238 U, 235 U, and 232 Th are primordial isotopes (Metcalf 1996), which decay through a series of radioactive elements up to stable Pb isotopes.…”

This study examines the radioactivity levels in Tunisia influenced by geological diversity and socio-economic influences. The region's landscapes are characterized by abundant mining and industrial activities, particularly phosphate mining and chemical sectors. Statistical analysis reveals that average radioactivity in the air (0.104 µSv) is lower than in soil (0.158 µSv) due to air dilution. Positive correlations are observed between air and soil radioactivity levels. Spatial distribution mapping shows higher radioactivity concentrations in mining and industrial areas. Radiation risk assessment calculates Ambient Dose Index (ADI), Equivalent Effective Dose Index (EDEI), and Excess Lifetime Cancer Risk (ELCR) have been evaluated. ADI values exceed WHO standard for infants and children. EDEI ranges from 0.006 to 0.309, with 54.2% of samples surpassing the standard value of 0.1. ELCR for a 40-year lifespan varies from 0.013 to 0.619. Continuous monitoring and protective measures are vital to reduce health risks associated with ionizing radiation exposure. The study emphasizes the need for safeguarding public health in regions with significant mining and industrial activities and raises awareness of potential health hazards related to high concentrations of radioactive elements.

“…The main source of 222 Rn in groundwater is the radioactivity of the rocks, while the emanation coefficient depends on the type of rock, its structure, and porosity; due to the presence of water in the pore space, radon atoms can dissolve in groundwater [58,59]. The underground drinking water supplies analyzed are located in five different geological or lithological units (L1-L5).…”

The activity concentrations of 222Rn were measured in 53 public water supplies of underground (50) and surface (3) origin, and the relation of such with five geological units where these supplies are located, in the central Ecuadorian Andes, was also explored. These units supply drinking water to 10 cities, located between the 1500 and 3120 m.a.s.l. The experimental setup consisted of the RAD7 radon detector and the RAD H2O degassing system. The 222Rn levels measured in groundwater ranged from 0.53 to 14.78 Bq/L while surface waters did not indicate detectable radon levels. The radon concentrations were below the parametric value of 100 Bq/L for water intended for human consumption, recommended by the European Atomic Energy Community (EURATOM) in its Directive 2013/51, and the alternative maximum contamination level (AMCL) of 150 Bq/L, proposed by the Environmental Protection Agency (EPA). The Pisayambo Volcanic unit, mapped as intermediate volcaniclastic to felsic deposits, presented a mean radon concentration higher than the other geological units and lithologies (9.58 ± 3.04 Bq/L). The Cunupogyo well (11.36 ± 0.48 Bq/L) presented a radon concentration more than 70% higher than the neighboring springs, which may be explained by its proximity to the Pallatanga geological fault. The maximum annual effective doses, by cities, due to the ingestion and inhalation of radon, ranged from 0.010 to 0.108 mSv and from 0.008 to 0.091 mSv, respectively; therefore, these waters do not represent a risk to the health of the population. In addition, a correlation was observed between the activity concentration of 222Rn and the activity concentration of the parent 226Ra in samples collected from some springs.
