Radon Testing

Did you know that radon levels vary by season?  Generally speaking, radon levels are lower in the summer than in the winter.  There are several reasons for this. Our homes act as vacuums that draw soil gas inside of them year round.  As the weather gets colder we heat our homes, which add to this natural draw through a process known as thermal stacking.  As a result, radon levels are typically higher inside our homes in the winter.  Did you also know that weather events such as high wind and brief but powerful storms can influence radon levels?  These can pressurize or depressurize our houses depending on wind direction, and atmospheric pressure.  EPA Radon Measurement Protocol recommends NOT performing a short term test of less than 90 days during these conditions.

EPA Radon Measurement Protocol requires certain testing conditions called “closed house” conditions to be strictly followed.  A few of these conditions are as simple as keeping all doors and window closed for 12 hours before and during the 48 hour test, normal entry & exit of the house are permitted.  Not burning woodstoves, blocking off window A/C units, and using bath vent fans normally are a few other conditions that are important when testing for radon.  This protocol is in place to standardize testing procedures for relatively consistent test results from property to property.  Knowing these standards allows a radon measurement specialist to test at the optimal time for the most accurate annual average.  NOT knowing these standards may cost you a mitigation system that wasn’t necessary, or conversely and more importantly, put your health at risk because the test results came back low, but the test was not valid.

When having a radon test performed, ask questions!  Make certain that the person testing is knowledgeable and informed on the EPA measurement standards, and they understand the importance of following these standards.  Radon testing is easy and affordable, with accurate results usually produced within 48-72 hours of the start of a test. The piece of mind from knowing how much radon is in your home is PRICELESS!
