Modern radon mitigation systems are designed to be quiet, ensuring minimal noise disturbance in your home.
Radon comes from uranium, but it is more directly produced by radium in the soil. Radon is the only element in the uranium decay series in the gas phase. It is inert, so it will not react with or stick to anything. It has a half-life of 3.8 days, which gives it time to be sucked into your home. After that, it decays into polonium. Polonium causes lung cancer when it decays in your lungs. Polonium is not inert and sticks to airborne particles that you may inhale or directly to your lung tissue.
