Radon Guides & Resources
The radon library, in plain English
These guides exist so you can understand the problem before anyone asks for your money. They cover the questions that actually come up: what a high test result means and what to do about it, how a mitigation system works part by part, which kind of test answers which question, how radon fits into a South Dakota home sale, and how to tell whether an existing system is still doing its job. Each one is written to be read in a few minutes, without a glossary. For quick one-paragraph answers instead, the FAQ page collects the questions people ask most.
