Some of the symptoms of radon gas exposure include a persistent cough that does not improve, coughing up blood, hoarseness, difficulty breathing, and wheezing. Resembling lung cancer, chest pains and recurring bronchitis or pneumonia are other signs of radon exposure, according to National Radon Defense.
Long-term exposure to radon — a radioactive gas found in water, soil, rock, natural gas and some building materials — has the potential to cause lung cancer. Since radon cannot be seen and has no scent or taste, some people do not realize that they are being exposed to the gas until their homes or offices test positive for it, they begin to experience symptoms, or they are diagnosed with lung cancer. Radon exposure is the second-leading cause of lung cancer, resulting in around 21,000 deaths every year, cites WebMD.
Radon poisoning can happen in areas with high concentrations of the gas, such as basements, underground mines and crawl spaces. The gas contains tiny radioactive particles that can be inhaled, may cause damage to the lungs, and may potentially lead to lung cancer, says National Radon Defense.
Almost one in 15 houses has unsafe radon gas levels, says WebMD, citing studies. Areas with large uranium deposits have a higher risk of exposure; however, just because one home has high radon gas levels does not mean that the home next to it does. This is because of constructions features and the exact positions of homes.
