That's because radon gas occurs naturally from the breakdown of uranium deep beneath the earth's surface. Obviously, certain areas of the country are more prone to radon than others depending upon the topography and soil structure. Radon testing can help you determine if your home is harboring this dangerous gas.
Where is radon most commonly found?
Most radon exposure occurs inside homes, schools and workplaces. Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation. Indoor radon can be controlled and managed with proven, cost-effective techniques.
Where is radon most likely to accumulate in a home?
basement About one in every 15 homes is thought to have high levels of radon. The highest concentration of radon tends to be found in the basement or on the first floor.
What type of building is most affected by radon?
Radon levels are generally highest in cellars and basements because these areas are nearest to the source and are usually poorly ventilated.
Is the risk of radon the same everywhere?
Radon is everywhere; formed from the uranium in all rocks and soils. Outdoors everywhere and indoors in many areas the radon levels are low and the risk to health is small. The darker the colour on the radon maps, the greater the chance of a high radon level in a building.
What time of year is radon highest?
winter The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
Do air filters help with radon?
Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.
Is radon in the ground everywhere?
Since uranium is essentially ubiquitous (being or seeming to be everywhere at the same time) in the earth's crust, radium-226 and radon-222 are present in almost all rock and all soil and water. The amount of radon in the soil depends on soil chemistry, which varies from one house to the next.
Should I walk away from a house with radon?
If a potential buyer conducts a radon test and those levels come back high, the buyer has the right to walk away from the sale (nearly all do) and you'll be obligated to disclose the radon to future buyers, reducing your appeal.
What time of year are radon levels highest?
Radon levels can vary by season, with the highest levels typically occurring during the months that we heat our homes. That means that even if your home's radon was below the EPA's suggested action level of 4.0 picocuries per liter of air during the warmer months, it could be above that level during the winter.
