“…The average values of the AED in the study area exceeded the recommended limit. Gyuk et al (2017) use Liquid Scintillation Counter to determine the radon concentration in groundwater and surface water sources from Idah and its environs. RnC in the borehole, well, and surface water samples ranged from 4.7Bq L -1 to 24.0Bq L -1 with an average value of 10.2Bq L -1 , 5.7Bq L -1 to 13.6Bq L -1 with an average value of 12.3Bq L -1 , and 1.9Bq L -1 to 4.5Bq L -1 with an average value of 3.1Bq L -1 , respectively.…”

Given the characteristics of radon, people may unwittingly be exposed to radon through water ingestion. Research on radon concentration has increased over the years due to its negative impact on the body being the major causes of lung cancer. This study reviewed twenty (20) journal publications on radon concentration in water sources (such as well, boreholes, stream and taps) in Nigeria from year the 2016 to 2023. The type of sample, sample location, devices used, the range and mean values of radon concentration (RnC) and annual effective dose (AED) were considered. From the reviewed journals, the average values of RnC ranged from 1.9 Bq/L to 88.0 Bq L-1. When compared with WHO and US EPA recommended limits of 100 Bq L-1 and 11.1 Bq L-1 respectively, all reviewed journals recorded average values of RnC below 100 Bq L-1 and 75 % of the reviewed journals recorded average values of RnC above US EPA recommended limit of 11.1 Bq L-1. The mean AED reported is within the range of 0.02 mSv yr-1 and 92 mSv yr-1 with 30 % above the recommended limit of 0.1mSv yr-1. This result shows that the majority of the radon concentration in water sources in Nigeria reported may not pose any immediate health risk. However, there is a need for continuous monitoring and protective measures to be taken.

“…Water is one of the most plentiful materials on earth and is a crucial component of all living things, according to a 2010 report by Darko et al It is utilized in many facets of daily life, including domestic work, agriculture, and the production of power. Water must be free of chemical, microbiological, and radioactive contaminants as a result [1] .…”

The most common supply of freshwater for drinking, irrigation, and other domestic uses is groundwater; however, because of increased radon concentrations brought on by mining activities, its quality is still a severe concern. Using a liquid scintillation detector, this study investigated the radon content, its related toxicity, and its risk to human health in the groundwater of the Keana in Nasarawa, Nigeria. Ten (10) borehole samples and five (5) well samples totaling fifteen (15) groundwater samples were taken. The results showed that the average radon concentration in water samples from Keana was 2.25 Bq/L. The mean annual effective dosage (ingestion) for adults and children in Keana was 0.016 mSv/y and 0.027 mSv/y, respectively. In Keana, the additional lifetime cancer risk per adult was 5.65 × 10–5, and per child, it was 8.79 × 10–5. The study’s radon concentration was lower than the benchmark of 11.1 Bq/L established in 1991 by the Nigerian Standard Organization and the US Environmental Protection Agency. The results of this study indicate that the level of radon is safe; as a result, people can continue farming and other activities. To reduce the risk of cancer, however, more research could be done in the area. Further research should be done by looking at additional sources in the study area in order to cover the entire zone. Further investigation should be carried out both during the dry and wet seasons because radon concentrations in groundwater alter over time due to dilution by recharge from rainfall.
