Test for radon



How do I test my home?

Radon test kits are available at EcoSuperior!

Long-term tests ($50) are the most accurate way to test your home. Prices include lab fees and return postage. EcoSuperior accepts cash or debit, Monday to Friday 8:30 - 4:30, at 562 Red River Road at Hill Street.

Complete instructions are included with your kit. The unit should be placed according to instructions in the lowest level of your home that is occupied 4 or more hours per day. Tests should be conducted in a bedroom, living room, or rec room. Do not test in a kitchen, bathroom, or hallway. You will obtain the most accurate results in winter, when windows and doors are closed. Place the device in a location that is representative of the air that you breathe, for example on a bedroom nighttable.  Do not move the device for the duration of the test. The unit should be left undisturbed for 90-365 days. When the testing period is over, place the unit and the data tracking sheet in the pre-paid postage envelope and mail to the laboratory. Test results will be sent to you by email or return mail.

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.

What do the test results mean?

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 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 200 Bq/mis not a "magic number" and other juristictions have set more proactive guidelines. The US Environmental Protection Agency's guildine 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.
