How an Alpha-track Radon Detector Works

Each RSSI Alpha-track radon gas detector contains a detector element, called a foil.  When radon atoms decay inside the detector, they release alpha particles.  If the alpha particles strike the foil, they make microscopic tracks in the surface of the foil.  When the detector is analyzed, the foil is chemically treated to enlarge the alpha tracks, which are counted on an automated system.  The average radon level is calculated from the number of tracks and the number of days the detector was exposed.  This level is reported in picocuries per liter (pCi/L).  

Radon levels vary in daily and seasonal cycles, and in response to weather conditions and ventilation patterns.  For these reasons, it is preferable to make the test period as long as possible.  A full year test provides the most reliable prediction of future radon exposure and health risk.  However, RSSI's Alpha-track detector can be used for tests as short as 14 days.

Any level of radon creates a risk of lung cancer.  The US EPA recommends that, to reduce the risk of lung cancer, corrective action be taken in every home with radon above the action level of 4 pCi/L.

One out of every 15 homes in the United States has radon levels above 4 pCi/L.  Most homes can have their radon levels lowered to below 2 pCi/L.  New homes can be designed to prevent high radon levels.
