*Effective August 29, 2025, the United States has suspended its duty-free “de minimis” threshold of US$800 for all countries, including Canada. All postal shipments to the U.S. valued under US$800 will require assessment and prepaid duties before packages cross the border. This applies to radon test kits.
Using the Kit
- The unit should be placed in the lowest level of your home, which is occupied for 4 or more hours per day.
- Tests should be conducted in a location that is representative of the air that you breathe most often (i.e., your bedroom night table, or living room.)
- When the testing period is over, place the unit and the data tracking sheet in the envelope (postage not included) and mail to the laboratory. Test results will be sent to you by email.
*Note:
- Do not move the device for the duration of the test.
- The unit should be left undisturbed for 90-365 days.
- Please contact our office if you have any questions about radon or your radon test results.
- A Radon Mitigation Demonstration room at our office offers additional information.

You've Received Your Test Results. Now What?
Radon is measured in Becquerels per cubic meter. Health Canada's guideline states that homes should not exceed 200 Bq/m3.
Health Canada recommends that homes with a long-term average between 200-600 Bq/m3 should be fixed within two years, and that homes with a long-term average above 600 Bq/m3 should be fixed within 1 year. Note that other jurisdictions may have different guidelines in place. The US Environmental Protection Agency's guideline is 150 Bq/m3, and the World Health Organization's guideline is 100 Bq/m3. Some homeowners with levels around 100-200 Bq/m3 choose to reduce their radon levels, especially if solutions are easy and cheap.
