Over the past few years, electronic radon monitors have become increasingly available and popular with consumers. In order to provide Canadian consumers with an unbiased performance-based comparison of these monitors, the Canadian National Radon Proficiency Program (C-NRPP) regularly conducts a series of performance tests. Details of the testing process can be found here.
Radon levels vary from day to day and week to week. Although the electronic radon monitors listed here provide results quickly, it is important to leave them in place for at least 3 months to get an accurate representation of your average radon level.
Short-term radon measurements can be misleading (either much lower or much higher than your actual average radon level).
Follow these guidelines when testing your home for radon:
The table on the BELOW summarizes the different devices that have been tested. These devices cannot be professionally calibrated and are not approved by C-NRPP for use by radon measurement professionals.
