There are two basic options for testing — one is to buy a do-it-yourself radon test kit and the other is to hire a radon measurement professional.
If you choose to perform the test yourself, radon detectors can be purchased over the phone, from the internet or from some home improvement retailers. The radon test kits will include instructions on how to set it up and send back to a lab for analysis once the testing period is over.
If you choose to hire someone to do the test for you, look for a service provider that has been certified through the Canadian National Radon Proficiency Program. Questions to consider asking the service provider include:
What type of radon test device do you provide, short-term or long-term?
Are you certified and trained to provide radon measurement services?
Are you familiar with Health Canada's revised guideline for radon exposure in indoor air?
Do you follow Health Canada's measurement protocols?
