Exposure to Residential Radon and Lung Cancer in Spain: A Population-based Case-Control Study Juan Miguel Barros-Dios, María Amparo Barreiro, Alberto Ruano-Ravina, and Adolfo Figueiras (May 2002).
An additive synergic effect between radon and tobacco was found. The results from this study suggest that, even at concentrations far below official guideline levels, radon may lead to a 2.5-fold rise in the risk of lung cancer. Furthermore, the synergy found between smoking and radon may prove useful when it comes to drafting public health recommendations. AmJEpidemiol 2002;156:548–55. View study (PDF)
Individuals holding the Residential Measurement Provider certification have demonstrated knowledge of U.S. EPA radon measurement protocols for the placement and retrieval of radon measurement devices. They have also demonstrated knowledge of the proper interpretation of results obtained in residential settings.
These individuals are authorized to place devices that are analyzed by a NEHA certified analytical laboratory. Depending upon the location of the laboratory where the devices are to be analyzed, and specific shipping arrangements that have been established, results are not generally available immediately upon conclusion of the radon test.
Since 1987, EPA has addressed public health risks from indoor radon, indoor asthma triggers, environmental tobacco smoke, and air toxics, in schools, public and commercial buildings, homes, and communities. Other program areas include mold, green buildings and international assistance in developing nations to reduce indoor smoke from household heating and cooking.
