Testing is The Only Way to Know. Since you can't see, smell or taste radon, testing is the only way to find out if you have a radon problem. Homeowners can measure radon concentrations in their homes themselves using inexpensive and easy to use test kits, or professional, certified testers can test a home.
Certified testers may charge $150 to $250 for the test, but results can be made available within 48 hours. When testing for a real estate transaction, it is recommended a qualified (certified) tester be used.
