Radon that enters your home eventually decays into radon decay elements. It is these decay products that are of concern to us. While radon is a gas, these radioactive elements are solid particles that become suspended in air. As we inhale these extremely small particles, they attach themselves to our lung tissue. Because these particles have very short half lives, our lungs do not have the time to exhale them out before they break down. It is the break down of these particles that releases alpha, beta, and gamma radiation directly into our sensitive lung tissue. Most hazardous of these is alpha radiation. It can kill a lung tissue cell, and/or cause a mutation in the cell’s DNA causing that cell to develop into a cancerous cell. This leads to an increased risk of developing lung cancer over prolonged exposure.
