Yes the EPA action level is 4.0 pCi/L, however that level was set nearly 30 years ago and new research is showing it is not as safe as once thought. Did you know over 2/3 of all radon lung cancer deaths come from levelsbelowthe EPA action level? In fact, the EPA action level is...
the US EPA has set an action level of 4 pCi/L. At or above this level of radon, the EPA recommends you takecorrective measuresto reduce your exposure to radon gas. This does not imply that a level below 4.0 pCi/L is considered acceptable, as stated inthe BEIR VI study. It is estima...
January is National Radon Action Month, and according to the U.S. Environmental Protection Agency (EPA), more than 6 million U.S. homes have indoor concentrations of radon that exceed safe levels (1). Radon causes between 3 and 14 percent of all lung cancer cases worldwide (2). If you...
In 1984 researchers found that naturally occurring radon is a much more pervasive threat to homeowners than had previously been thought.Two years later, the EPA established 4 picocuries of radon per liter of air (pCi/l) as the "recommended action level." A picocurie is one-trillionth of a...
Radon is found all over the United States. Scientists estimate that nearly one out of every 15 homes in this country has radon levels higher than four picocuries per liter, the level above which EPA recommends that homeowners take corrective action. Picocuries per liter is how radon in the ...
What about radon in the West? Indoor pollution by radon is not a remote threat, nor is it a completely new one. But it's much in the news nowadays. A three-year study, released in January by the National Academy of Sciences Research Council, corroborates previous estimates that radon ran...
. The state of Georgia keeps records on radon test results. Chatham County, Georgia, where Savannah is, shows up as Zone 3 on the EPA map. The highest level recorded in that county is 49.7 picoCuries per liter (pCi/L). That’s really high. (See theGeorgia radon results mapfor more....
Rust is the common name for a very common compound: iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen — so readily, in fact, that pure iron rarely occurs in nature. Iron (or steel) rusting is an example of corrosion: an ele...
The hazard presented by radon comes from prolonged exposure to unacceptably high levels of the gas. The need to know and control the concentration level of radon in your home is a cause for action but not one for panic. Begin the process of testing and then, if necessary, explore theoption...
Even in developed nations, where a plentiful supply of water is sometimes taken for granted, the value of water is increasing among the people and their governments. HowStuffWorks has already found that we can't manufacture water, so what exactly will happen if we run out? It's ...
