High Levels of Radon in Washington County

Radon gas is a carcinogenic gas found in many homes throughout Washington County. The gas occurs from the breakdown or radioactive decay of uranium underground and arises through cracks in the foundation of homes. The EPA in the United States has said quite bluntly that any exposure to radon has some risk of causing lung cancer. Even though many people have not heard of radon, it is the second leading cause of lung cancer in the United States right behind smoking. For non smokers though it is the primary cause of lung cancer.

In the early 1980's Congress passed the Radon Act 51 which 0.4 pCi/L was to be the safe target for indoor levels of radon. If you look at the pie chart to the right you'll see in Washington County 48% of homes has radon levels above 4 pCi/L which is 10 times the acceptable level. 18% of homes have radon levels between 2 and 3.9 pCi/L which is still well above the safe acceptable level.

The EPA has set an action level of 4 pCi/L. If your home is above 4 pCi/L it is imperative to install a radon mitigation system. You should not assume, just because your home may be below 4 pCi/L it is safe or acceptable. Reducing radon levels below 2 pCi/L will reduce your risk of lung cancer from radon by an estimated 50%. To keep your family safe you should really get levels below .4 pCi/L. 

According to the EPA people receive higher doses of radiation from radon than from all other sources of radiation combined.

Radon Health Impacts

Radon damages lungs by attaching to dust particles in the air. Those dust particles are breathed in and embed themselves deep in the lung tissue causing a small amount of damage accumulating over time. Our lungs are one of the most important organs in our body as they deliver oxygen to our blood supply and remove carbon dioxide. An impairment in oxygen deliver could potentially lead to other health problems such as chronically be fatigued, tired all of the time, irritability, and other issues. Most of all long term exposure to radon can lead to lung cancer.
