RSSI's Alpha-track Radon Detectors

Testing your home for radon is easy, inexpensive, accurate, and reliable.  RSSI manufactures and analyzes the most accurate alpha-track radon gas detectors available today.

There are two types of RSSI alpha-track radon detectors to choose from:

  • RSSI Alpha-track AT-101; and

  • RSSI Alpha-track AT-102.

RSSI's alpha-track radon detectors do not require closed house conditions and are not affected by heat, humidity, or shipping delays.  To view technical information regarding both of RSSI's alpha-track radon detectors, visit our Technical Information page.

Alpha-track detectors can also be purchased in large-quantity professional packaging for schools, commercial buildings, multi-unit testing projects, and for use by radon professionals.  For more information, see Testing Large Buildings and Radon Professionals.

How an Alpha-track Radon Detector Works

Each RSSI Alpha-track radon 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) or becquerels per cubic meter (Bq/m3).  

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 30 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.
