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.

Does humidity affect radon levels?

#2 Weather Conditions Rain, thunderstorms and high wind can also have an affect on radon testing results. Radon readings have been known to go down when the outdoor wind speeds increase during periods of high humidity. When the seasons change such as fall to winter, radon testing can be affected.

Does Radon increase over time?

The EPA even recommends checking radon levels at least every two years as radon flow can increase over a timescale longer than one calendar year. This is to say, just as radon levels fluctuate within a calendar year, they also fluctuate as years pass.

Will 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. … Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.

Do sellers have to fix radon?

“The seller usually pays for the mitigation and any retesting. Radon in most cases can be mitigated to an acceptable level, but seek the advice of a radon mitigation specialist if you have questions or concerns.”

Is radon a deal breaker?

Radon is dangerous because it can cause lung cancer. Every year in the U.S. some 21,000 people die because of radon. Radon has a nickname that could easily scare away any potential home buyer: “The Silent Killer.” But there’s no need for radon to be a deal-breaker in any real estate transaction.

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 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.

Can 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.

Is a radon level of 6 dangerous?

Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.

Is radon worse in summer or winter?

LEVELS of radon gas in the soil may be as much as 10 times higher in the summer than in the winter, when most testing for the cancer-causing gas is done, a Pennsylvania State University study has found.

Is it OK to live in a house with radon?

There are no safe levels of radon, and there’s no way to eradicate it. In homes where there are smokers present and smoking indoors (instead of outside), the risk of developing lung cancer will be much higher. Levels above 4 pCi/L are considered actionable, so those are in the dangerous levels of radon for indoors.

How do I get rid of radon in my home?

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.

Should I worry about radon gas?

Radon is considered to be the largest source of exposure to natural ionising radiation. Exposing sensitive bronchial cells to radon is known to cause damage in proportion to the number of cells exposed. Radon concentration is highest indoors, particularly in houses and small buildings.

Where is Radon most commonly found?

Radon is present everywhere in the United States. Levels of the gas differ from state to state, but it is particularly high in North Dakota and Iowa. The U.S. Environmental Protection Agency’s Map of Radon Zones shows the potential for elevated radon levels for each county in the United States.

Are DIY radon tests accurate?

If you’re considering a DIY radon test kit, you need view the test only as a means of determining if there is a radon problem at all. The accuracy of a DIY radon test kit is always uncertain because it’s conducted by an amateur. A DIY radon test kit will either be charcoal or alpha track.

Do radon levels go up in the winter?

Basically, radon is coming up through the soil all around us. Unfortunately, during the winter or rainy seasons, the ground around your home can become saturated with water and in some cases frozen. … Many homes have poor indoor air quality and higher radon levels because the home is closed up during winter months.

What time of year are radon levels highest?

winterRadon levels can vary but tend to be highest during the winter when homes are being heated and the air is stagnant. Since most people don’t open their windows during the winter, there’s nowhere for radon to escape too which causes it to build up in the home. This makes winter the best time for radon testing.

Can you sell a home with radon?

There are no laws that prevent you from selling a home with elevated radon, so you can do it. But, in certain states there are laws that require sellers to provide a radon disclosure in real estate documents. In some, the disclosure must also include known testing results and maintenance data for a mitigation system.
