Radon gas is a significant health threat linked to thousands of preventable deaths each year. One population that may be at increased risk from harm from radon exposure is African Americans. However, little is known about what African Americans think or know about radon. A theoretically based evaluation of radon awareness and reduction campaigns was conducted with African Americans. The knowled...

Introduction Lung cancer is the leading cause of cancer death in the U.S. with radon exposure as the second leading cause of lung cancer after smoking and the number one cause of lung cancer among nonsmokers. The Environmental Protection Agency (EPA) estimates that one in fifteen homes nationwide has elevated radon levels. Although public outreach efforts promote radon testing and subsequent mi...

Lung cancer is the leading cause of cancer-related deaths worldwide. Radon exposure is the second leading cause of lung cancer, following tobacco smoke. Radon is not only an independent risk factor; it also increases the risk of lung cancer in smokers. Numerous cohort, case-control, and experimental studies have established the carcinogenic potential of radon. The possibility of radon having a ...

Concentration ofradon in supply air 3 pCi/1 Minimum reduction factor for radon 100 Time for which reduction must be maintained 10 days ^—— 7 • From the tests completed recently2 at the SNO underground laboratory at the INCO Creighton mine it was found that activated charcoal has considerable adsorption capacity even at room temperature for the removal ofradon from compressed air. It was also f...

Radon gas in the home is a major source of public radiation exposure and an established cause of lung cancer. A range of techniques are available to reduce high indoor radon concentrations in homes. Information on some 2,700 radon remediation projects has been analysed with the aim of identifying the factors that influence the performance of various remediation methods, including the specific r...

The research of the dynamics of radon in various environments, especially indoors, is of great importance in terms of protection against ionizing radiation and in designing of measures for its reduction. Research of radioactive emanations (of radon (222Rn) and thoron (220Rn)) are in the domain of radiation physics, but since a few decades ago, subject of radioactive emanation involves many othe...

This paper presents the experimental results of utilizing a flexible thin-film membrane as a passive barrier to radon gas diffusion. Nine commercially available membranes of various compositions and thicknesses were evaluated as retardant to radon gas diffusion. The radon gas concentration ratios across the thin-film membranes alone and in combination with an adjacent concrete sample (effective...

Radon remediation in schools was identified early on as a potential priority for governments. The exposure reduction attributable to schools remediation can be substantial (1). Epidemiological and technical radon research has produced information which has enabled attention to be turned to specific effectiveness questions regarding radon identification and remediation programmes in buildings, i...

OBJECTIVE Radon and cigarette smoking have synergistic effects on lung cancer, even when radon concentrations are relatively low. Working through an electric utility company, we sought to reach smoking households with low radon concentrations and motivate smoking cessation or prohibiting smoking in the home. DESIGN Eligible homes (n = 714) were randomised to receive: (1) the Environmental Pro...
