The Harmful Effects of Radon Gas

Radon is a natural but dangerous substance. The tasteless, odorless, colorless gas poses major health risks and causes the highest amount of lung cancer deaths annually, after smoking. Fortunately, it can be easily detected and addressed.

What Is Radon Gas?

• Radon is the result of a natural, radioactive breakdown of uranium in water, rock, and soil. Once released, radon then enters a building through weak points in the foundation, becoming trapped inside and inhaled by occupants. Radon is a nationwide problem and is not confined to any one area or region. The gas can permeate any building, such as a school or office, but is most likely to affect people in their own homes.

How Does Radon Cause Illness?

• Radon gas decays, forming radioactive particles, which can become trapped in the lungs. As they continue to break down, the particles release tiny burst of energy, which can damage the lungs and lead to cancer. Not everyone who is exposed to radon will develop cancer, and the onset of disease can occur many years after exposure.

Testing for Radon

• According to the EPA, 1 in 15 American homes is estimated to have elevated levels of radon; therefore, testing for the substance is of vital importance. Fortunately, testing is a relatively simple process. Testing kits are available online and in stores, and a State Radon Office can provide a list of professional testers; having one inspect a home prior to purchase is a wise move.

Lowering Radon Levels

• If a test shows elevated levels of radon, there are options for remedying the situation. According to the EPA, "there are several proven methods to reduce radon...the one primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside." This solution does not require major renovations, and its effectiveness can be increased via small repairs, such as sealing cracks in a house's foundation.
