This area has one of the highest levels of radon in the nation. The tests we've done on homes in this area show three of five have elevated levels.

And a lot them confuse radon with carbon monoxide and talk about how it's not a risk unless you have an old furnace.

It's the old ostrich with the head in the sand. They don't want to know (if there's radon in a home) because then they might be responsible and they will have to deal with it before they sell it.

Minnesota is ahead of most states in innovative, healthy things like smoking bans, but there are no regulations that make people test for radon or for builders to build radon resistant homes.

It's a lot easier and cheaper to do it during new construction. If you have to do mitigation later, it's $1,200 to $2,000.

I had heard about them [acid tests] and was deeply offended along with everybody else in my sort of Eastern Orthodox Church of LSD, ... We thought it was a very serious sacrament and should not be handed out in bathtubs for people to drink as much as they want.
