Test for between 3 and 12 months.
Health Canada recommends that we all should test for radon for a minimum of 3 months. The amount of radon entering a building can fluctuate up and down quite a lot over a short period of time. This is normal and by having a long (90+ days or more) radon test, these fluctuates are averaged out, returning the real radon level of a house.
Here are the three options used by most people:
- A minimum period 90-day test. The best time to start these are in September to October or February to March.
- Perform a longer (6 months) test starting at any time of year.
- Deploy your test for an entire year.
The device is only active once you have opened the vacuum-sealed plastic bag it will arrive in. As soon as you open this vacuum-sealed bag, the test starts. The most important thing is to accurately record the start and end date of the test, via the registration process.
