- Avoid using exhaust fans, which increase radon levels.
- Radon comes into your home or office because the air pressure is lower than it is outside, drawing radon in like a vacuum.
- Exhaust fans further decrease the air pressure, so using them actually increases the concentration of radon in the air.
Moreover, Does vapor barrier prevent radon? For a new home, a high-performance, properly installed vapor barrier is a critical component of an effectively designed ASD system — with a fan drawing air from underneath the barrier, radon is prevented from entering the house and instead vented out through a network of passive or active venting pipes.
What time of year are radon levels highest?
Indoor radon levels are normally at the highest in the winter or colder months because of the thermal stack effect, a snowy barrier, and tightly sealed homes. Cold temperatures increase the pressure within the home, meaning more air is being pulled in from the ground, which elevates the risk of radon entering the home.
Likewise, Which creates the greatest radon threat? For most people, the greatest exposure to radon occurs in the home where people spend much of their time, though indoor workplaces may also be a source of exposure.
How do I get rid of radon 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.
Does vinyl flooring reduce radon?
As a side benefit, it will also reduce radon levels in your home! DO use moisture-resistant flooring, such as ceramic tile or vinyl composition tile. If you want the look of wood, cover the slab with a vapor-control layer with taped seams and install a glued or dry-fit engineered click-lock floating floor system.
What can be used as a radon barrier?
To prevent dangerous radon from entering your home, apply high-quality products like Polyguard Underseal® Underslab Membrane and Polyguard TERM® Barrier Systems.
Where is radon most prevalent?
Radon gas is a ubiquitous element found in rock and soil. The burning of coal and other fossil fuels also releases radon. When radon escapes from soil or is discharged from emission stacks to the outdoor air, it is diluted to levels that are normally, but not always, lower than indoor air.
Does ventilation reduce radon?
Increase air flow in your house by opening windows and using fans and vents to circulate air. Natural ventilation in any type of house should not be considered radon mitigation since it is only a temporary strategy to reduce radon.
Does radon go through plastic?
While radon typically finds its way into homes through cracks or holes in a foundation it has the ability to penetrate through paper, plastic, sheetrock, wood, and insulation. This fact can be a little frightening because it seems that there is no way to keep radon out of our homes.
Does a dehumidifier reduce radon?
No, buying a dehumidifier will not make radon go away. Research conducted by the US Environmental Protection Agency (EPA) has clearly disproved this idea.
Which states have the most radon?
Here are the 10 US States with the highest average Radon levels:
- Alaska (10.7)
- South Dakota (9.6)
- Pennsylvania (8.6)
- Ohio (7.8)
- Washington (7.5)
- Kentucky (7.4)
- Montana (7.4)
- Idaho (7.3)
Does paint stop radon?
As a chemically inactive gas, radon can diffuse through concrete, making sealing alone inconsistent at reducing radon levels. In our years of radon reduction experience, we have seen people use epoxy paints, waterproofing paints, concrete sealers and other substances to “seal” radon out of buildings.
Does opening windows get rid of radon?
As a temporary solution, however, you can reduce radon levels simply by opening windows. 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.
What season is radon highest?
To answer that question, yes, radon levels in a home tend to be higher during the winter. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.
Do air purifiers help with radon?
Do Air Purifiers Help With Radon Gas? 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. As mentioned earlier, radon tends to attach itself to numerous airborne and water particles.
What state has lowest radon levels?
Hawaii has the lowest radon levels of all 50 states, with an average level of 0 pCi/L.
…

Does running furnace fan reduce radon?
In many homes, blowing air in through an existing central furnace is quite practical. The use of an exhaust fan to pull air out of the house may decease the interior air pressure and draw more radon inside.
Does HVAC help with radon?
This study shows that even the most standard ventilation provided by an HVAC system can reduce levels. The impact of radon is statistical and improvements can continue to be gained at levels below the current 4.0 pCi/l action level.
Does air conditioning reduce radon?
A decrease in the mean value of radon and its attached progeny was found when AC was working. The mean value of radon equilibrium factor F was also lower when AC was working (0.49) than when it was off (0.61).
Will an air purifier 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 worse in winter or summer?
Since radon levels are likely to be higher during the winter you can expect the level to not rise much higher during the rest of the year. You are also most vulnerable to radon during the winter since you will be inside for much of it and breathing the same reheated, recirculated air.
Does opening windows reduce radon?
As a temporary solution, however, you can reduce radon levels simply by opening windows. 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.
