Why is Radon Dangerous?

Most homeowners know about the dangers of smoke and carbon monoxide and have detectors in their homes to guard against those dangers. However, not many homeowners know about radon and what it can do to their health. Radon that is found in a home with limited ventilation can spread  rapidly increasing the odds of those living the home to be at risk for lung cancer.
