Radon Atlas is run by OutreachVoice, a trade name of 1236326 Alberta Ltd., 325-918 16th Avenue NW, Calgary, AB T2M 0K3.
You are already listed, free, if you hold current C-NRPP certification in an area we cover. If you would like a page of your own, the details form is here and takes about three minutes.
If your listing is wrong, out of date, or you would rather not be listed at all, say so above and it is done the same day.
Everything here is free to use and free to share with clients. If you would like the radon numbers for the specific communities you work in, tell us which ones and we will pull them for you. There is no charge and nothing to sign up to.
We cannot tell you whether your house has a radon problem, and anyone who says they can without testing it is guessing. What we can do is point you at the questions most people have and at the certified companies in your area.
If you have a question this site does not answer, ask. If it is a good one we will add it to the questions page for the next person.
Please tell us. A number, a map, a company listing, an interpretation, anything. We will check it, fix it if it is wrong, and say that we changed it. A site whose whole point is honest data does not get to be precious about corrections.
