Hi everyone, Here in Canada we tend to have uranium in the ground, and hence radon gas can show up in basements. I had an interesting experience with this over the holidays. If you want to know if you have radon, you can get a sample kit from Home Depot, mail it away, and get a test result. That's cool, but one time, one place. I purchased an electronic meter that actively reads the radon levels, so I could first measure, and then map out the radon levels around my house.
The end result was realizing that the basement sump was somewhat strong source of radon. Although my house on average was below the threshold of 200 Bq/m^3, my sump had a reading of over 600. A friend of mine measured his sump and got a reading of 2700! So over the holidays I purchased a "radon fan" and built a venting apparatus to capture the air in the sump and vent it out the side of the house. Now my house reads radon levels basically equal to atmospheric. So - wondering if anyone else has had a similar experience? I was initially worried about "discovering" radon in my house but really, it is so common. I don't think enough people are aware. The fix in my case was relatively easy and not expensive at all. ...Steve
