Radon is a toxic, colourless, odorless gas that exists as a normal by-product of uranium and radium radioactive decay. Their gas, radon, contributes a significant portion of normal background radiation found throughout the planet. Small quantities of these radioactive elements can be present in the earth’s rocks-especially in some granites and shales, in the soil and in groundwater.Visit Radonova for more details.
Radon is the noble gases ‘ heaviest-about eight times as dense as normal air. It tends to accumulate in low-lying and confined areas, because of this. There, it can rise to large enough amounts to be considered a potential health risk.
Radon-Is it important?
In the United States alone, statistics suggest that prolonged exposure to radon is a contributing factor in 20,000 lung cancer deaths per year. The Surgeon General warned that, in the United States, radon is the second leading cause of lung cancer-behind smoking. When it comes to radon exposure, smokers and little children are considered to be at greater risk. Statistics also show that radon exposure causes more deaths a year than drunk driving, drowning and home fires.
While no level of radon exposure can be deemed 100 percent healthy, certain sensitivity to low background radon radiation will always be available. While the radon concentrations differ by geographic area, for the United States the national average outdoor radon concentration is about 0.4 picoCuries per liter (pCi / L). Ideally, radon levels should be the same inside a home as outdoors, but these results are hard to achieve. The average concentration of radon inside is 1.3 pCi / L.
The EPA is now proposing that radon rates above 4.0 pCi / L should be minimized by using a radon reduction device.
How do we know if we have a problem with the Radon?
Radon testing methods are numerous. While there are some very sophisticated, automated, high-tech and costly instruments that can constantly track radon rates, most radon experiments use some sort of collector that captures the radon effects over days, weeks, or even months. Ventilation and external factors such as rain can have short-term impact on radon rates. In a household, radon rates can fluctuate from day to day, and hour to hour. Sometimes it may be necessary to take longer-term or repetitive tests to get the most accurate results.
The low cost and efficiency of an impartial, competent, trained radon tester is a good investment, despite the expertise needed to make an accurate assessment. A long-term check to give a good estimate of the average level of radon over time is suggested for a home owner or a home seller who wants to put a house on the market. Similarly, a home buyer wants assurance that a house is free of dangerous levels of radon but requires faster results using a short-term test.
Whatever methods are used, remedial action should be taken where repeated or long-term levels of radon exceed 4.0 pCi / L.
