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.

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.

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.

The first step to knowledge is to know that we are ignorant.
