Can a significant number of radon-related lung cancers be averted by mitigating existing single-family houses whose radon is above the action level? Would societal resources be used cost effectively by a comprehensive measurement and mitigation policy using the existing or some other radon action level? Simple questions, complex answers. The risk of lung cancer depends on the radon exposure in ...

In this paper, the averages annual radon concentrations in buildings placed a karst area are analyzed order to understand which factors may affect occurrence of high levels indoor. Statistical analysis on dataset is performed using analytical described by two or three according characteristic measured buildings. The that determine higher terms arithmetic mean (AM) at ground floor (GF) mainly pr...

The aim of the study was to assess the effect of residential radon exposure on the risk of lung cancer in never-smokers and to ascertain if environmental tobacco smoke modifies the effect of residential radon. We designed a multicentre hospital-based case-control study in a radon-prone area (Galicia, Spain). All participants were never-smokers. Cases had an anatomopathologically confirmed prima...

Continuous generation of radon gas by soil and rocks rich in components the uranium chain, along with prolonged inhalation progeny enclosed spaces, can lead to severe respiratory diseases. Detection radon-prone areas acquisition detailed knowledge regarding relationships between indoor variations geogenic factors facilitate implementation more appropriate mitigation strategies high-risk residen...

Although the principal means to confirm indoor radon involves testing buildings, soil-based investigations are of value in identifying land areas that pose special concerns. Ideally, soil-based measurements would relate to radon production, diffusive transport, and convective transport into buildings. This paper briefly reviews technologies for measuring radon in soil gas, radon flux, and soil ...

We measured radon (222Rn) concentrations in Iowa and Minnesota and found that unusually high annual average radon concentrations occur outdoors in portions of central North America. In some areas, outdoor concentrations exceed the national average indoor radon concentration. The general spatial patterns of outdoor radon and indoor radon are similar to the spatial distribution of radon progeny i...

introduction the potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. while γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the p...

The radioactive properties of radon have been known for decades, but the risks of exposure have been understated in most professional healthcare curriculums. Healthcare providers in areas with low levels of radon exposure may not consider radon to be a main source of concern in the development of lung and other cancers. Just as nurses counsel patients to avoid tobacco exposure, they should advo...

BACKGROUND Associations have been reported between maternal radiation exposure and birth defects. No such studies were found on radon. Our objective was to determine if there is an association between living in areas with higher radon levels and birth defects. METHODS The Texas Birth Defects Registry provided data on all birth defects from 1999 to 2009 from the entire state. Mean radon levels...
