Scientists warn dangerous radon gas may be increasing lung cancer risks
Scientists warn that dangerous radon gas may be increasing lung cancer risks. Researchers at the Ghana Atomic Energy Commission say the radioactive gas is naturally present in the environment, and prolonged exposure could increase the risk of lung cancer, even among non-smokers. Dr. Irene Opoku-Ntim, Senior Research Scientist at the Commission, said, "There are other pollutants, as we all know, that we talk about, the dust, the burning and all those things, but there's also another hidden risk that is radon, which is giving people lung cancer beyond smoking and the other pollutants that we know out there."
Radon seeps from the ground into homes through cracks, holes and poorly ventilated spaces. The World Health Organisation says indoor radon levels above 100 becquerels per cubic metre pose a health risk and should trigger action to reduce exposure. Researchers in Ghana have identified some areas with higher concentrations of radon. Dr. Opoku-Ntim said, "So we have a radon map for Ghana, which is a preliminary one that we've done. We are still working on that. That shows that places that have high radon concentration is being correlated with places that have earthquakes." Research has been done in high radon areas such as Weija, Kasoa, and McCarthy Hill.
Scientists say there are ways to reduce the risks. They advise on how to build if soil tests show high radon levels. They recommend building foundations with polyethene and sealing cracks in homes. Researchers say greater awareness and testing could help families better protect themselves.
Quick Summary
Ghanaian scientists are raising concerns about a dangerous, unseen pollutant. Prolonged exposure to this environmental hazard may have serious health consequences - particularly for those most vulnerable.
