Abstract
Radon in household water, particularly from groundwater sources, is a well-known health concern. Radon in groundwater is typically produced by radium in the aquifer's rocks, which may be originated from geogenic uranium or be transported from distant areas. In this study, radon levels were measured for the first time in groundwater samples (N = 80) collected from the foothills of the Kumaun Himalaya using the scintillation-based RnDuo technique, with the aim to assess whether exposure to radon in the water poses a significant health risk to the general public. Some (N = 41) of these samples were also analyzed using inductively coupled plasma mass spectrometry (ICP-MS) and LED fluorimetry for uranium concentrations, to investigate if geogenic uranium is source of radon in groundwater. The estimated health risks of radon and uranium in the analyzed water samples suggest no potential danger to the public. Weak correlations were observed between radon and uranium concentrations, indicating that the source of radon in groundwater is not related to local geogenic uranium mineralization. The findings will be valuable for future research on radionuclide exploration and radiation protection applications.

JOURNAL OF ENVIRONMENTAL RADIOACTIVITY 2022; 247:106852. [PMID: 35305305 DOI: 10.1016/j.jenvrad.2022.106852] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 02/28/2022] [Accepted: 02/28/2022] [Indexed: 06/14/2023]
Abstract
Groundwater radon contamination is a serious global concern for its eco-toxicological effects. The major health hazard occurs due to toxic indoor air inhalation and consumption of contaminated drinking water supplied from different distribution systems, especially groundwater. There are fragmented reports on the measurement of radon contamination and their health consequences with physical radon removal strategies as well as characterization of inhabitant microbial communities. As it concerned with human health, collective information is much essential on their groundwater distribution, their physicochemical properties and possible mitigation strategies, not done so far. In such prospect, this review summarizes the physicochemical properties of radon, their sources, global as well as Indian groundwater radon contamination scenario, health effects and inhabitant microbes along with their survival strategies. It also summarizes the physical radon removal techniques and especially emphasizes the microbes based bioremediation process as well as a combination of both as a future effective radon remediation process.
