RSSI's Alpha-track radon gas detector does not require closed house conditions and is not affected by heat, humidity, or shipping delays. For more information regarding RSSI's Alpha-track radon detector, click here.
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 8 days.
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).
