Should I test for radon?

Yes. Ignorance is not bliss.

The EPA has set the action level for radon at anything greater the 4pC/L. This means that when your radon test comes in above that number, or even close to it, you should have a radon mitigation system installed. According to the EPA map North Idaho is Zone 1, which means levels are predicted to be above 4pC/L. It is always best to know what is coming into your house.
