A Radon abatement service is the best way to protect your home. The Environmental Protection Agency (EPA) and the Surgeon General’s Office have urged widespread testing for radon. Radon is the nation’s second leading cause of lung cancer after smoking. Up to 36,000 lung cancer deaths are attributed to radon each year.
There is technically no safe radon level, since one alpha particle can theoretically begin the chain of events that leads to lung cancer. Our goal is to reduce radon as close as possible to the average outdoor level of 0.4 pCi/L. Almost 90% of the homes we mitigate re-test between .5 and 1.5 pCi/L. Our guarantee is always to below 4.0 pCi/L at a minimum. Many houses can be guaranteed to below 2.0 pCi/L, but not those with long-term radon levels exceeding 6 -7 pCi/L.
Radon levels are always changing. Seasonality can play a role – winter is worse than summer due to the heating of the house. The heat rising in the house creates a stronger vacuum on the soil. Time of day (the diurnal effect) also plays a role, as well as the weather situation, wind levels, etc. Prolonged periods of windy, rainy and snowy weather cause prolonged spikes; so in our climate, winter time radon levels are usually significantly higher than the summer. The cooling of the house in summer reduces the vacuum on the soil. If you consistently have high levels over a period of time, or if you get a result above 4.0 pCi/L in summer, you probably need to move forward with mitigation.
