Radon gas is a scary thing. It's a naturally occurring, cancer causing gas that is odorless and colorless. However, it is an easily remedied problem, with radon remediation typically costing between $1,000-2,000. So, what does a radon inspection entail?
A house will be under closed house conditions during the test - no open windows or doors. (Sellers may have to kick on their A/C during this time - no fresh air for you!) An inspector will place radon detectors on the lowest floor of living space. Living space includes any area that can be finished in the future into living space. Full Basement? Living Space. Crawl Space? Not living space. The testing equipment will be in the home for 48 hours and the tests will be averaged to come up with the average radon reading in the home.
If the radon reading comes in at 4.0 pCi/L or higher, you should install a radon remediation system. If the test comes back at 3.9 pCi/L or lower, no remediation is necessary.
The EPA has some really good information on radon on their website. Here is the link to their Home Seller/Home Buyer guide to radon:
