It's a good idea to test basement radon levels when buying a new house. In my state, it's a check box on the required paperwork, so every buyer can see it's an option. The tests are cheap and quick. Check with your state for any help with finding testers or paying for the tests and mitigation systems. Radon levels vary a lot. In Pennsylvania, the worst areas lie along the Appalachians, but even then neighboring houses can have huge differences in radon. So even if your soon-to-be neighbors didn't have a problem, do the test.
