How Does Radon Testing Work?

WHAT TO EXPECT FROM RADON TESTING

The Radon Testing Process

We help you plan your test, choose a suitable measurement location and understand the result so you can decide what to do next.

1. Plan your test

Discuss your property, how the rooms are used and any existing readings. We’ll help you choose a suitable testing approach and device location.

2. Measure over time

Keep the device in its agreed location and follow the testing instructions. Continue for the planned duration to capture how radon levels change over time.

3. Understand your result

Review the reading together with the test dates, location and device information. We’ll explain the result and whether further testing or a mitigation assessment is appropriate.

UNDERSTANDING YOUR TEST

A reliable result takes time.

 Health Canada recommends testing for 3–12 months, including at least 91 days during the heating season. Use the long-term average when assessing your result, rather than individual hourly or daily readings.

If your long-term result exceeds 200 Bq/m³, take steps to reduce radon. If it is below 200 Bq/m³ but includes fewer than 91 heating-season days, retest during the next heating season.

Where Should You Test Your Home for Radon?

Radon levels can vary between floors and rooms, so choosing the correct testing location matters.

Health Canada recommends measuring radon on the lowest level of your home that is regularly occupied. This might be a finished basement, bedroom, home office or main-floor living area.

The device should remain in an appropriate location throughout the long-term measurement period, away from windows, exterior doors, ventilation outlets and other conditions that could affect the reading.

RADORA can help Ottawa homeowners determine a suitable testing location and understand what their results mean.
