Why is radon gas harmful?
Radon is radioactive and unstable. In a very short period of time, it decays and emits alpha particle radiation, which severely damages our DNA in such a way that is almost impossible for our bodies to repair without introducing genetic errors (mutations). These errors trigger a worsening cycle of DNA mutation that drives cancer formation. Hence, radon is listed as a category 1 carcinogen (cancer-causing agent), meaning that it is known to cause cancer in humans. As radon is inhaled into our lungs, it primarily triggers the formation of lung cancer – the number one cause of cancer death in Canada – even in folks who have never smoked. Younger people, especially children, are the most at risk from the DNA damage caused by radon exposure. The risk of cancer goes up with greater radon levels and prolonged exposure over a lifetime.
