Radon - Long-term test instructions
Organization: Health Canada
Congratulations on making the decision to test the radon level in your home.
1. Figure out the best place to put the radon detector
- Place the detector on the lowest lived in level of your home – where members of your household spend at least four hours a day (family room, living room, den, playroom or bedroom).
- Place the detector in the typical breathing zone, 0.5 to 2 m (1.5 to 6.5 ft) from the floor, away from an exterior wall, and away from other object to allow for normal air flow.
- Place the detector on any flat surface like a desk, table or shelf.
- Hanging the detector from the ceiling or on a wall is also an option
- Place the detector in the kitchen, bathroom, laundry room, closet or unfinished areas of the basement.
- Place detector on an exterior wall, near air vents, windows or doors.
- Place detector near heat sources (fireplaces or direct strong sunlight).
- Place on or near electronics (TV, stereo, speakers, computer, etc.) or appliances (fridge, microwaves, etc.).
2. Starting your radon test
- Take the detector out of the bag and make sure the number on the detector matches the detector number on the Tracking Sheet included in the test kit.
- Write the test start date, time and location on the Tracking Sheet.
- Place the detector in the chosen location. Put the test kit Tracking Sheet and return materials (instruction forms, return detector bag and envelope) in a safe place.
- Put a reminder in your calendar to return the detector 3 months from the start date. Include a reminder where you stored the test kit return materials. Leave the detector in place for at least 3 months (it’s ok if you do it for longer – up to 12 months).
- Do not move the detector during the testing period.
3. Ending your radon test
- After 3-months (or more) it’s time to send the detector back to the lab for analysis.
- Put the detector into the zip-top bag provided (or a regular ziplock bag) and carefully close the bag.
- Record the test stop date/time on the Tracking Sheet.
- Put the bag containing the detector and the completed Tracking Sheet into the return mailing envelope provided.
- Mail the radon kit as directed in the instructions provided with your kit.
- You should receive your results via email or mail within a few weeks.
- If your results are 200 Bq/m3 or above, take action to reduce your radon level.
