Changes in weather – particularly extreme weather events – can change the pressure differences and therefore change how radon enters your home. Some weather events, like storms, typically cause radon levels in a home to rise. Other events, like heavy winds, can cause radon levels to either rise or fall.

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.

What time of day is radon highest?

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.

What factors affect radon level?

Conclusion. Many factors can give either a false negative or a false positive when conducting a radon test. High winds, barometric pressures, temperature, rain, and your home's construction all play a role in radon readings.

Can radon levels increase over time?

Radon does not build up in a residence over time due to its short half-life (3.8 days). Many conditions could affect the measured radon concentration over time in a residence.

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.

Why does radon go up at night?

How we live – air remains dormant when no one is at home, or when homeowners are sleeping at night – which can lead to elevated radon levels. This is in contrast to when you move around the house, creating more circulation which renews the air.

Does rain make radon worse?

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 air purifiers reduce 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.

Will running a fan reduce radon?

Running a window fan in a basement window reduces radon levels, but only if the fan blows air into the basement. A fan blowing air out of the basement increases negative pressure, which can actually increase radon levels.
