Bonnie is a 4 ½-year lung cancer survivor. During her initial prognosis her doctor asked if she was ever exposed to radon. She did not know much about radon. When she tested her cabin the level was 30 pCi/L, much higher than the 4 pCi/L action level. Bonnie wants to make sure everyone tests their home for radon because prevention is much easier than the road she travelled.
