BACKGROUND Radon is the second risk factor for lung cancer after tobacco consumption and therefore it is necessary to know the burden of disease due to its exposure. The objective of this study is to estimate radon-attributable lung cancer mortality in Galicia, a high emission area located at the Northwest Spain. METHODS A prevalence-based attribution method was applied. Prevalence of tobacco...

Background: While in the open air the amount of radon gas is very small and does not pose a health risk, in confined spaces, radon can accumulate to relatively high levels and become a health hazard. Exposure to high levels of radon has been associated with an increased risk of lung cancer, depending on the time length of exposure. Radon level in dwelling of Shiraz with 1,200,000 popul...

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: radon and thoron are invisible, odorless, heavy and radioactive gases which are ubiquitously present in dwellings and in the environment. in the present work, seasonal variation of indoor radon, thoron and their progeny concentrations has been studied in the dwellings of industrially polluted cities in district faridabad, haryana and district mathura in uttar pradesh. materials and ...

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...

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...

background: in this study are submitted the radon concentration measurement results of four underground mines: stanterg, artana, hajvali and badovc, which are owned by trepça enterprise, kosovo. the mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. the radiation exposures caused by radon and radon daughters was determined an...

To consider the total exposure to indoor radon and thoron, a concept of equivalent radon concentration for thoron is introduced, defined as the radon concentration that delivers the same annual effective dose as that resulting from the thoron concentration. The total indoor exposure to radon and thoron is then the sum of the radon concentration and the equivalent radon concentration for thoron....

Although radon dose to lungs comes mainly from shortlived radon daughters, most of its estimations for general population is based on the measurements of radon gas concentration instead of radon progeny and acceptance of a constant equilibrium factor between radon and its short-lived decay products. It is so because integrating passive measurements of radon gas concentration are simpler and che...
