Will running a fan 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. Running a window fan in a basement window reduces radon levels, but only if the fan blows air into the basement.

Does circulating air reduce radon?

Ventilation is key for reducing radon levels. Whenever possible, have several windows open on the lowest level of your home or office, which is closest to the soil and source of the radon. Even a small crack allows fresh air to flow in, lowering the concentration of radon in the air.

Can you run ceiling fan 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.

How do you reduce radon in your home?

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.

Is radon higher after rain?

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.

Does a dehumidifier reduce 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 a dehumidifier help with radon?

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.

Does finishing a basement reduce radon?

Radon levels are above recommended EPA levels. Radon levels must be reduced even if you are not finishing your basement. Because it comes from the ground, radon levels are usually highest in basements.

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.

Does central air reduce 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 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 natural ventilation reduce radon levels?

Natural ventilation should only be regarded as a temporary radon reduction approach because of several disadvantages: discomfort due to loss of conditioned air, increase in expenses for conditioning additional outside air, and concerns about security. Sealing cracks and other openings in the foundation is a basic way to reduce radon levels.

How can I reduce radon gas in my home?

Keeping cracks and openings tightly sealed also reduces the loss of conditioned air. However, the Environmental Protection Agency doesn’t recommend sealing as the dominant or sole radon reduction method, because it’s neither proven to significantly reduce levels of radon gas, nor provide consistent results.

Does sealing reduce radon gas levels?

However, the Environmental Protection Agency doesn’t recommend sealing as the dominant or sole radon reduction method, because it’s neither proven to significantly reduce levels of radon gas, nor provide consistent results. You may always be finding new places to seal and recurring cracks making sealing quite fickle.
