Radon - Long-term test instructions

Congratulations on making the decision to test the radon level in your home.

1. Figure out the best place to put the radon detector

DOs:

• 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

DON'Ts:

• 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.
• Follow the instructions provided with the test kit to record the start date, time and location.
• Place the detector in the chosen location. Put the materials received with the test kit (instruction forms, return envelope, etc.) 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 materials. Leave the detector in place for at least 3 months (it's ok if you do it for longer – up to 12 months).

3. Ending your radon test

• After 3-months (or more) it's time to send the detector back to the lab for analysis.
• Follow the instructions provided with the test kit to record the end date and time.
• Follow the return instructions provided with your long-term test kit. If you have misplaced the instructions, contact the test kit provider.
• Mail the radon detector to the lab as directed in the instructions provided.

4. Results

• You should receive your results via email or mail within 3 – 6 weeks.
• If your results are 200 Bq/m³ or above, take action to reduce your radon level.
