Radon Gas is a radioactive product that is the result of decaying Uranium. Uranium is found is soil and rock throughout the world. It has a 4 trillion year half-life (meaning, it takes 4 trillion years for it to lose only half of its radioactivity). Needless to say, there's a LOT of it around. As the uranium decays, it changes chemically into the element Radium. Radium is also radioactive, but does not move through the soil. However, when Radium decays, it becomes a gas and that gas is called Radon.
Radon, though radioactive, is too large and heavy in its initial form to be dangerous to humans. But Radon also decays. It is the radioactive byproducts of Radon decay that cause real damage to humans. As Radon decays into various elements, Polonium in particular, little "explosions" occur, thrusting out alpha particles from the atom. Because the decaying Radon products are so small and light at this stage, it easy for them to enter the lungs. Once inside the lungs, these little alpha explosions happen inside the tender lining of lung tissue, causing damage to the cells. Extended exposure to this kind of activity increases one's risk of developing lung cancer dramatically. If you're a smoker, the numbers are even higher.
Since Radon is a gas, it is extremely capable of finding its way into your home through tiny cracks in your foundation or slab, or even by going right through the slab. Therefore, it cannot be stopped by simply sealing your basement. Stopping this dangerous Radon gas requires a Radon Mitigation system installed by a PA licensed professional like the professionals at Pittsburgh's own U.S. Radon Professionals.
