Semi-experimental evaluation for radon exhalation rate and excess lifetime cancer risk from potential radon exposure for using fly ash building materials
“…This indicates a potential cancer risk for individuals exposed to the affected water in the future. The estimated ELCR in this study was higher than the reported ELCR in Vietnam 63 but lower than the ELCR associated with exposure in Iran 64 .

Geospatial methods, such as GIS and remote sensing, map radon levels, pinpoint high-risk areas and connect geological traits to radon presence. These findings direct health planning, focusing tests, mitigation, and policies where radon levels are high. Overall, geospatial analyses offer vital insights, shaping interventions and policies to reduce health risks from radon exposure. There is a formidable threat to human well-being posed by the naturally occurring carcinogenic radon (222Rn) gas due to high solubility in water. Under the current scenario, it is crucial to assess the extent of 222Rn pollution in our drinking water sources across various regions and thoroughly investigate the potential health hazards it poses. In this regard, the present study was conducted to investigate the concentration of 222Rn in groundwater samples collected from handpumps and wells and to estimate health risks associated with the consumption of 222Rn-contaminated water. For this purpose, groundwater samples (n = 30) were collected from handpumps, and wells located in the Mulazai area, District Peshawar. The RAD7 radon detector was used as per international standards to assess the concentration of 222Rn in the collected water samples. The results unveiled that the levels of 222Rn in the collected samples exceeded the acceptable thresholds set by the US Environmental Protection Agency (US-EPA) of 11.1 Bq L−1. Nevertheless, it was determined that the average annual dose was below the recommended limit of 0.1 mSv per year, as advised by both the European Union Council and the World Health Organization. In order to avoid the harmful effects of such excessive 222Rn concentrations on human health, proper ventilation and storage of water in storage reservoirs for a long time before use is recommended to lower the 222Rn concentration.

Determinations of specific activity concentrations for Uranium-238, Thorium-232 and Potassium-40 in 10 commercial phosphate fertilizers samples from various countries (Iraq, Iran, Jordan, Kingdom of Saudi Arabia, Italy and Turkey) were accomplished by the use of high purity germanium detector device. Radiation hazard indices [(Annual Effective Dose Equivalent) in, (Annual Effective Dose Equivalent) out, Equivalent Activity of Radium, Dose Rate of Absorbed Gamma, Activity Concentration Index , Internal and External Hazard Indices and (Excess Life Time Cancer Risk) out] were also investigated. The acquired outcomes were fewer than the advisable limits identified by (UNSCEAR, 2000).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
