You can pick up a Geiger counter for about the same price, but will detect all radioactive sources.. if you know which radiation it emits you can figure out relative radon levels

Which would you recommend to sit in a basement for active radon detection? I live in the Midwest and basements have to be monitored here. Just has a newborn and don't want to risk anything.
