RADON testing

If you don't test, you don't know

The only way to know your radon situation is to test it.  We offer radon measurement services using C-NRPP approved devices (E-PERM, Alpha Track, and Continuous Radon Measurement).  These devices can be used for short-term radon measurements from 48 hours to long-term radon measurements.  While a short-term test might appear to be desirable, it is important to understand that long-term tests (i.e., greater than 90 days) provide a better picture of the average annual radon level.  Short-term tests are suitable for determining the radon potential of a building and assessing the early performance of a mitigation system.  We also complete short-term tests to support real estate transactions.

Both the E-PERM and Alpha Track devices are very unobtrusive and do not require an external power source.  As air passively diffuses into the device, the decay of radon is measured.  In the case of the E-PERM, radon decay causes a decrease in a statically charged plastic disk (electret).  Measuring the charge on the electret before and after sample collection allows for the determination of the radon concentration.  The decay of radon in the Alpha Track device causes marks on a plastic strip.  These marks (or tracks) are subsequently counted to determine the radon concentration.











Health Canada has established a radon guideline of 200 Bq/m³.  For comparison, the World Health Organization has set a radon guideline of 100 Bq/m³.  The United States Environmental Protection Agency has set a radon guideline of 148 Bq/m  (4 pCi/L).  While these guidelines help to understand radon concentrations, there is no known safe level of radon exposure.
