Question: How To Lower Radon Levels In 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.

How do you reduce radon levels naturally?

Other Ways to Reduce Radon 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.

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.

What causes high radon levels in basement?

Radon comes from decaying Uranium that is contained in the rock and soil beneath the basement (under the foundation) of every home. This process actually draws air more forcefully between the high and low-pressure areas and can pull more air from the rock and soil beneath your home impacting your radon levels.

Does a dehumidifier help with radon?

No, buying a dehumidifier will not make radon go away. Radon must be removed by a remediation method like active soil depressurization (ASD), which ironically has been shown to be even more effective at removing humidity from a home than a dehumidifier in the same EPA study.

Does opening a window 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. Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.

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.

Will running a fan reduce radon?

In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.

Can you run dehumidifier during radon test?

Turn off all air moving devices during the test. This would include ceiling fans, dehumidifiers, regular fans, HEPA or any other kind of filtering device that moves air. Do not operate fireplaces or heating stoves during the test unless they are your main source of heat.

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.

What are 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.

Does radon come from Granite?

Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. Radon released from granite building materials can be released over the lifetime of use but typically will be diluted by ventilation.

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.

Can ceiling 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 painting basement reduce radon?

Finished or Painted Basements Painted Walls – Sealing only the floor with RadonSeal can help. Much more radon tends to penetrate through the slab than through the walls, because radon gas is trapped underneath between the footings. Soil gas outside the basement walls can easily escape upwards to the atmosphere.

Are radon levels higher at night?

During the day, the sun beats down and heats up the house from the outside in, but at night, there is a rapid cooldown. This results in slightly higher radon levels during the day, rather than at night.

Does an HRV remove radon?

To me, this is by far the simplest solution when it comes to radon mitigation. It works in new builds and existing homes, and only requires you have a Heat Recovery Ventilator (HRV). This exhausts the old air containing radon, replacing it with fresh air from the outdoors.

How long does radon take to affect you?

Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop. Early signs and symptoms of lung cancer may include: persistent cough.
