To find out the level of radon in any indoor space you have to test for it.

Testing for radon is easy and inexpensive.

There are three basic steps:

Step 1: Purchase a long-term radon test kit. (The average cost is $30 to $60.) Put it in an appropriate place (read the directions) and leave it there for at least three months. The ideal time to test is between September and April as windows and doors are usually kept closed. You can also hire a radon professional to test the space.

Step 2: At the end of the three months, send the radon test kit to the laboratory address included with the kit. The laboratory will analyze the kit and send a report back to you with your radon levels.

Step 3: If the radon levels are above the suggested guidelines, Health Canada or a certified radon professional can offer options for what to do next.

More information, including how to test, is available on our Radon page.
