• Radon is a radioactive gas released from the normal decay of uranium in rocks and soil (see Question 1). • Radioactive particles from radon can damage cells that line the lungs and lead to lung cancer (see Question 3). • Radon is the second leading cause of lung cancer in the United States and is associated with 15,000 to 22,000 lung cancer deaths each year (see Question 4). • Studies showing...

The Ohio Radon Information System (ORIS) internet site at http://www.uioledo.edu/-aprs/oris/ is one of the most comprehensive sites on indoor radon available on the World Wide Web. It was developed by the authors under a research grart from the Ohio Department of Health and U.S. Environmental Protection Agency. It is estimated that from 700 to 1300 people die annually in Ohio from radoninduced ...

The annual effective dose to Chinese population from natural radiation exposure is about 3.1 mSv/y, of which 1.56 mSv/y or 50% is due to the exposure from radon and its daughters [1]. The enhanced natural radiation level results mainly from indoor radon concentrations rising by 70%, compared to the previous data in 1990s [1, 2]. Based on the research, the increase in indoor radon concentrations...

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: radon is one of the most important radioactive elements which is released by natural decay of available uranium and radium in the ground. the presence of radon gas is common, wherever those faults are located there. radon concentration of various drinking water resources of bam villages; located near bam fault; was measured. materials and methods: this cross-sectional study was cond...

introduction recent studies of public underground parking lots showed the influence of radon concentration and the probable discomfort caused by parking cars. materials and methods radon concentration was measured in semi-closed public parking lots in the six governorates of kuwait, using durridge rad7radon detector (usa). results the peak radon concentration in the parking lots of kuwait gover...

This study sought to determine the effect of environmental conditions on radon levels in a home. The two independent variables in the experiment were (1) whether or not it was raining and (2) whether the HVAC system on the main level of the home was set to “ON” for continuous ventilation or “AUTO” for forced air only to maintain temperature. A recently calibrated Radalink AirCat® radon detector...

As information on indoor air quality accumulated* it became apparent that radon and its progeny are invariably present in indoor environments and that concentrations may reach unacceptably high levels. The lung cancer excess anong miners exposed to radon progeny raised concern that exposure to radon progeny might also cause lung cancer in the general population. This presentation first provides...

(222)Rn concentrations in drinking water samples from Beijing City, China, were determined based on a simple method for the continuous monitoring of radon using a radon-in-air monitor coupled to an air-water exchanger. A total of 89 water samples were sampled and analyzed for their (222)Rn content. The observed radon levels ranged from detection limit up to 49 Bq/L. The calculated arithmetic an...
