“…The study was done using the RAD7, an active electronic device made in the United States by the Durridge Company. The level of radon in the water is higher than the allowed level of 11.1 Bq/L [22] . (Elzain, 2014) estimated radon concentrations in 248 water samples collected from various water bodies in Sudan using a solid-state nuclear trace detector.…”

Radon is an inert gas that is very dangerous to humans and exists in varying proportions in soil, air and various water sources. Additionally, radon gas has a shorter lifespan but poses a greater public health risk. Humans are good users of water, whether through food, drinking water, vegetables, showering or washing dishes, but we don't yet have a good understanding of the dangers of radon gas and we need to do more research because it is a major one of the water sources. Factors responsible for various cancers such as lung cancer and gastric cancer. This review uses different data from a number of studies in different countries (Brazil, Sudan, India, Syria, Iraq, Yemen and Qatar) that use RAD7 detectors due to their higher accuracy and faster detection measurements. This study found that Brazil's average radon level is high (36.1 Bq/L), which is higher than the world drinking water standard value (103 Bq/L). There are many influencing factors in each country, and the issue of low radon concentrations in water is controversial.

In this research, radon concentrations in surface water samples were measured at 8 stations and along 8 boat survey routes in the lower Nam Phong River, Khon Kaen Province, Thailand, using the RAD 7 Radon Detector and RAD AQUA accessories. The results of radon concentration at the 8 stations along the Nam Phong River ranged from 0.16 to 4.87 Bq/L, with an average of 1.17 Bq/L. For the boat survey routes along the Nam Phong River, radon concentrations ranged from 0.04247 to 0.12342 Bq/L, with an average of 0.07422 Bq/L. These results were lower than the maximum contaminant level of radon in water (MCL), 11.1 Bq/L, as the United States Environmental Protection Agency recommended. Finally, the results were used to assess various health risks to people in this research area, contributing to determining the public safety of radon exposure in the lower Nam Phong River.

“…Previous research was primarily devoted to radon concentration measurement in drinking water sources with little or no attention to the associated health hazards (Alomari et al, 2019;Garba et al, 2013;Kessongo et al, 2020;Mostafa et al, 2022;Sharma et al, 2018) and on the basis of the available literature from the present study locations, no study of this nature has been conducted in these communities. It is therefore.…”

The attendant health consequences arising from both the consumption of thawed radon and the inhalation of released radon air and its progenies emanating from the various drinking water sources in our community underscores the relevance of the current research. This pioneering study attempts to evaluate the Rn-222 concentration, the annual committed effective dose (ACED) and the related health risk factors of randomly selected 26 water samples from Apa and Agatu Local Government Areas (LGAs), Benue South, Nigeria. The results of the analysis via liquid scintillation counter, revealed the highest radon values of 13.365±1.065 Bq/l and 18.248±1.740 Bq/l for well water samples higher than the action level of 11.1 Bq/l by USEPA were found in the villages of Apa and Agatu LGAs respectively, while 5.551±0.479 Bq/l lower than the tolerance limit was recorded for the surface water samples. The annual committed effective doses estimated for the different ICRP age groups (3 months, 1 year, 5 years, 10 years, 15 years and above 17 years) were below the acceptable 1 mSv/y baseline but displayed a significant and consistent rise with the age and water consumption frequency of the populace. Excess life cancer risks (ELCR) and the induced lung cancer cases per year per million persons (LCC) for ingestion and inhalation of radon by the inhabitants of the study areas were calculated. ELCRing and ELCRinh mean values of the radionuclide showed different variations below the standard reference line. The average values recorded for the lung cancer cases due to ingestion and inhalation of radon (LCCing) and (LCCinh) and the probability of an individual developing cancer over a lifetime exposure to radioactive element (ELCR) were found to be significantly lower than the suggested 170–230 per year per million persons and 0.29 mSv/y global mean value respectively. This implies that the evaluated radon parameters for ingestion and inhalation in the study areas do not pose any immediate radiological health effects to members of the public but periodic monitoring of the quality of the groundwater sources should be encouraged.
