Abstract
BACKGROUND: Radon is a naturally occurring radioactive gas and a level 1 carcinogen. It acts synergistically with cigarette smoke to cause lung cancer. In Ireland, radon is estimated to be associated with 13 % of all lung cancers. Rapid access lung cancer clinics (RALC's) were established in the UK and Ireland to improve lung cancer management outcomes. There has been no attempt to date to provide advice on household radon exposure assessments in this setting. AIMS: We performed a prospective feasibility study of radon assessment in our RALC to test the hypothesis that patients would avail of this service and that it would provide an opportunity for secondary prevention in at risk persons. METHODS: We investigated household radon levels in consecutive patients who were newly referred with symptoms of lung cancer to the RALC in Galway University Hospital, Ireland over a 6-month period. RESULTS: Of 50 patients enrolled, 42 returned valid results. Overall 21 % of patients had radon levels recorded above the national reference level. Only 5 % of patients were aware of the association between radon gas and lung cancer. Smokers were significantly less likely to engage fully in radon testing. CONCLUSIONS: The development of RALC's offers a novel opportunity to integrate the concepts of radon exposure, cigarette smoking and the development of lung cancer, and to reinforce this message in the minds of at risk patients.
