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).
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.
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
out of every 15 homes in the
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.
