Consumer-Grade Electronic Radon Monitors

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:

  • Place your radon monitor in a room that is occupied for at least 4 hours each day. For detailed instructions on placing your radon monitor, click here.
  • Test your home for a minimum of 3 months, preferably during the heating season when indoor radon levels are typically the highest.
  • If you only have access to a digital monitor for less than 91 days, we recommend that you follow up with a long-term radon test. You can find a list of online retailers here: https://takeactiononradon.ca/test-for-radon/radon-test-kits/
  • Consider the long-term average radon level when deciding whether to mitigate your home. Electronic radon monitors each have a different method of averaging the data; we recommend you read the manufacturer’s user guide to determine how to read the long-term average radon level.

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.
