Background: Radon and its daughters are amongst the most important sources of natural exposure in the world. Soil is one of the significant sources of radon/thoron due to both radium and thorium so that the emanated thoron from it may cause increased uncertainties in radon measurements. Recently, a diffusion chamber has been designed and optimized for passive discriminative measurements of rado...

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...

For underground particle physics experiments, noble gas radon from U-chain decay series could be a source of serious background events. We have developed a high sensitivity detector for radon using electrostatic collection and PIN photodiode. Recently, we have developed a new type of radon detector. We report basic performance of the new 80L radon detector.

There is a growing recognition in the United States and Europe that health care is driven to a significant extent by an emphasis on consumer choice and demand. As consumers, people regularly choose their own solutions for health promotion and maintenance, solutions which may or may not be sanctioned by mainstream medicine. Radioactive radon therapy exemplifies a non-sanctioned treatment eagerly...

• 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...

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...
