It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Radon from soil gas is the main cause of radon problems.
Where is radon most commonly found?
Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour.
What causes high radon levels in a house?
CAUSES OF RADON IN YOUR HOME: CRACKS AND GAPS Coupled with any cracks in the foundation and gaps in your flooring and around pipes, and radon has easy access to your home. A DIY solution is filling in every crack and gap with caulk to limit radon’s access to your living space.
Where is radon most likely to accumulate in a home?
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.
Where does radon gas come from?
Radon is constantly being generated by the radium in rocks, soil, water and materials derived from rocks and soils, such as certain building materials. Radium is a decay product of uranium which is naturally occurring in the soils and rocks of the earth’s crust.
How do you eliminate radon?
Other radon reduction techniques that can be used in any type of home include: sealing, house or room pressurization, heat recovery ventilation and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction.
Should I be worried about radon?
Radon Is a Cancer‑Causing, Radioactive Gas But it still may be a problem in your home. When you breathe air containing radon, you increase your risk of getting lung cancer. In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today.
What are the first signs of radon poisoning?
A persistent cough could be a sign that you have radon poisoning. Persistent cough. Hoarseness. Wheezing. Shortness of breath. Coughing up blood. Chest pain. Frequent infections like bronchitis and pneumonia. Loss of appetite.
Should you walk away from a house with radon?
Should you walk away from the deal? Consumer Reports says you don’t have to. Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home.
How can radon be prevented?
More Ways to Take Action Stop smoking and discourage smoking in your home. Increase air flow in your house by opening windows and using fans and vents to circulate air. Seal cracks in floors and walls with plaster, caulk, or other materials designed for this purpose.
What type of soil has the most radon?
Granitic type soils present higher levels of radon gas. Non-granitic soils have traditionally been considered to have very low radon levels.
Who is most susceptible to radon?
Who Is at Risk of Radon Exposure? Radon level If 1,000 people who smoked were exposed to this level over a lifetime… * 20 pCi/L About 260 persons could get lung cancer 10 pCi/L About 150 persons could get lung cancer 8 pCi/L About 120 persons could get lung cancer 4 pCi/L About 62 persons could get lung cancer.
Do air purifiers reduce radon?
Yes, air purifiers help with radon gas reduction to some extent. The air purifiers with activated carbon filter technology are highly effective in trapping radon gas.
What are 5 facts about radon?
Here are a few facts about radon, and what you can do to help keep your family healthy and safe. Radon is radioactive. Radon is a naturally occurring radioactive gas. Radon causes cancer. No immediate symptoms. You must test for radon. Radon is present indoors and outdoors. Radon can build up in any building.
What rocks cause radon gas?
The results showed that, on average, homes on limestone, dolostone, and some shales have higher indoor radon concentrations than homes on siltstones, sandstones, and surficial deposits.
Where is radon found in homes?
It sometimes gets concentrated in homes built on soil with natural uranium deposits. It can enter buildings through cracks in floors or walls, construction joints, or gaps in foundations around pipes, wires or pumps. Radon levels are usually highest in the basement or crawl space.
Will opening the basement windows before a radon test lower the results?
Unfortunately, no, opening the windows does not reduce radon. It is not a gas that will just permanently escape the home like smoke from something burning in the oven. The radon may seem to leave when the windows are open, but as soon as they are closed, it is back.
How accurate are radon tests?
“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.
What happens if you are exposed to radon?
Being exposed to radon for a long period of time can lead to lung cancer. Radon gas in the air breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung cancer.
