Although there is no definitive test that can tell you for sure whether you’ve been exposed to radon, it’s still a good idea to address your concerns with your doctor. Together the two of you can decide whether you should be monitored more closely for signs of lung cancer or other potential issues.
This would also be an excellent time to do anything else you can to reduce your chances of developing problems. If you’re a smoker who’s also possibly been exposed to radon, quitting as soon as possible is imperative. You should also monitor yourself for any potential signs of a health issue (such as a persistent cough, hoarseness, or chest tightness) and discuss anything worrisome with your doctor right away.
