“…This includes surface and underground waters, in which the underground water includes thermal and mineral water. These types of water resources are a key identification of the economic growth and social prospect of a country [1][2][3]. Thermal and mineral waters (including spa waters) are known as valuable natural resources and are popular for medical therapy, such as the treatment of rheumatic diseases, skin diseases, arterial circulation disorders, muscular and skeletal damage, peripheral nerve damage, and other disorders [4].…”

“…Because of the popularity and importance of these types of water, their quality must be strictly controlled, including the concentration of radioactivity. For underground water, the physicochemical conditions and geological formation of the area strongly affects the occurrence of radionuclides, which can effect human health by the ingestion of drinking water from wells utilized in water-supply systems [1,6,7]. Therefore, the radiological characterization of drinking water has been a topic of concern of several organizations worldwide.…”

There is little available information on the radioactivity concentrations in the thermal and drinking water sources in North Vietnam. In the current study, the gross alpha and gross beta activity concentrations were determined in 8 water sources in the area. The average activities of gross alpha and beta in the 8 sources are 38.7 mBq L− 1 and 88.0 mBq L− 1. These activity concentrations are lower than WHO recommendations for drinking water. In this study, the gross alpha and gross beta show a weak correlation.

“…In the underground of the Tilis , ca locality, Dordea [60] mentioned the presence of gneiss rocks, exploited as a valuable resource for the construction industry [61]. Otoo et al [46] observed that due to its properties (density, durability, and water absorption capacity), this rock stores many natural radionuclides, including 226 Ra [61,62], which contributes significantly to the gross alpha activity [63], and 40 K [61], which plays an important role in the gross beta activity [63], also showing a significant positive correlation with 222 Rn abundance [61]. Other rocks described as being associated with high radon levels, especially in groundwater, are granite [62,64,65], shale, and phyllite [64].…”

From a public health perspective, the monitoring of water quality intended for human consumption belongs to the operational and audit management of the supply zones. Our study explores the spatial and temporal patterns of the parameters of drinking water in Sibiu County, Romania. We related the relevant physical-chemical parameters (ammonia, chlorine, nitrates, Al, Fe, Pb, Cd, Mn, pH, conductivity, turbidity, and oxidizability) and radioactivity (gross alpha activity, gross beta activity, and radon-222 content) from a 5-year survey to the water source (surface water and groundwater, which may be of subsurface or deep origin), space (sampling locality) and time (sampling month and year). We conducted a combined evaluation using the generalized linear mixed models (GLMMs), Pearson correlation analysis of the physical-chemical parameter, multivariate linear redundancy analysis (RDA), t-value biplots construction, and co-inertia analysis. The obtained regional model shows that the source, locality, and month of sampling are significant factors in physical-chemical parameters’ variation. Fe and turbidity have significantly higher values in surface water, and nitrates and conductivity in groundwater. The highest values are recorded in January (nitrates), March (Cl, ammonia, pH) and August (Fe, turbidity). The RDA ordination diagram illustrates the localities with particular or similar characteristics of drinking water, two of which (rural sources) being of concern. The water source is the best predictor for radioactivity, which increases from surface to ground. The gross alpha and beta activities are significantly and positively correlated, and are both correlated with conductivity. In addition, the gross alpha activity is positively correlated with nitrates and negatively with pH, while the gross beta activity is positively correlated with Mn and negatively with Fe; these relationships are also revealed by the co-inertia analysis. In conclusion, our model using multilevel statistical techniques illustrates a potential approach to short-term dynamics of water quality which will be useful to local authorities.

“…In fact, another screening parameter for approaching radiological risk management in drinking water is measurements of the gross α and β activity concentration. This kind of measurement is frequently adopted due to its simplicity and low cost [21,22], even if it does not take into consideration the specific radionuclides for the alpha emitters [13,21,23,24]. Conversely, the technique used for the evaluation of the gross beta activity can detect most of the beta particles emitters that can be found in water in non-emergency situations.…”

The physical–chemical properties of water are closely linked to the geological nature of the site where they are located. This aspect becomes even more interesting when analyzing the natural radionuclides in the drinking water of a volcanic territory such as Campania in southern Italy. This study concerned the measurement of activity concentration of gross alpha and beta, radon, and tritium to evaluate their biological impact. The measurements were carried out using alpha spectrometry for alpha emitters, proportional counter for beta emitters, the electret system for radon in water, and finally liquid scintillation for the measurement of tritium concentration. The biological impact was assessed considering the indicative dose, if applicable, and the effective annual dose of radon. Although the results show that the values are below international and national references, the radiological characterization of drinking water is of fundamental importance to optimize the radiation protection of the population.
