Radon comes naturally from uranium through a long series of radioactive transformations, meaning it undergoes radium decay before it is transformed into a chemically reactive atom. Radon enters basements as the air tends to be at lower pressure than the soil gases under the slab.
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 radon gas in houses?
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.
How common is radon in homes?
It’s common: About 1 in every 15 homes has what’s considered an elevated radon level. The gas is odorless and invisible, says the EPA, and it causes no immediate symptoms, so the only way to know if your home is affected is by testing your individual residence.
How do you eliminate radon?
Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.
Can air filters remove 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.
Is it OK to live in a house with radon?
If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Over time, these radioactive particles increase the risk of lung cancer. It may take years before health problems appear. People who smoke and are exposed to radon are at a greater risk of developing lung cancer.
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.
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.
How do you test for radon in your home?
You can hire a professional tester or do it yourself with a kit you buy at a hardware store or online. Follow the instructions for leaving the kit in your house for the required number of days. Then mail it to a lab and wait for the results. If radon levels in your home are high, you can take steps to lower them.
How do you know if your house has radon?
Radon testing is easy and the only way to find out if you have a radon problem in your home. Since you cannot see or smell radon, special equipment is needed to detect it. When you’re ready to test your home, you can order a radon test kit by mail from a qualified radon measurement services provider or laboratory.
How do you fix radon in a basement?
Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.
Does opening windows reduce radon?
Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open. Homes tend to have lower air pressure than their surroundings, which draws radon into the basement.
Does finishing basement reduce radon levels?
Radon Gas Problems in Basements You may want to reduce the radon level to a minimum just to protect your family’s health, particularly, if the children spend lots of time in the finished basement. Before basement remodeling, seal the concrete with RadonSeal™ to reduce radon to a minimum and to keep it that way.
Can plants help with radon?
Common houseplants like spider plants, palms, ferns and ivies are quite efficient at cleansing the air and making home air healthier. But the few sources I did locate indicated that indoor plants have little or no effect on radon gas.
Does rain increase radon levels?
Certain types of weather can have a greater impact on your home’s radon levels. Wind and rain storms create the largest variables of radon levels when testing for radon gas. Rainier days tend to result in noticeably higher radon levels. This is because rainy days are often coupled with lower barometric pressure.
Do fans reduce radon?
Ceiling fans can reduce radon levels by 50%. If used along with positive ion generators, ceiling fans are capable of reducing radon levels by 90%. This is achieved by a phenomenon called plate-out, which neutralizes radio-active particles.
Does radon come through concrete?
Radon, soil gasses, and water vapor will easily pass through any openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.
Can radon affect dogs?
Many pets spend on average 90-95% of their time inside. You may not know that your pet has radon poisoning until they start showing cancer-related symptoms, such as fever, abnormal swellings, coughing and lack of appetite, excessive throwing up, lameness, and breathing difficulties.
What season is radon highest?
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.
