What Time Of Year Are Radon Levels Highest?

Is radon higher in the summer or winter?

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..

What time of year is best to test for radon?

Q: When is the best time to test for Radon? Generally the winter or summer months when heating or cooling systems are running is the best time to test for Radon. For short-term tests, the house should be closed up for 12 hours before the test begins and throughout the test.

Does Radon increase in winter?

Greater concentrations of radon can enter the home during winter months. … Since less radon in the soil is able to escape through the frozen ground in the yard, the house may be pulling in higher concentrations of it. 3. Closed house conditions during the winter can keep radon gas levels from being diluted by fresh air.

How do you lower radon levels in a home?

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.

Do Ceiling fans reduce radon?

One of the most effective systems for reducing the concentration of unattached radon daughters is a ceiling fan, or air circulating fan; sometimes coupled with an ion generator. Positive ion generators work best. … A Casablanca type ceiling fan can reduce radon by up to 95%.

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.

Will 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.

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.

Should I worry about radon gas?

As the National Cancer Institute notes, “Long-term exposure to radon can lead to lung cancer.” It is long term exposure that matters, so it’s never really too late to check your home for radon. At the very least, you might find out you do have high radon levels, allowing you to take action to protect your home.

How do I get rid of radon in my home?

In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) 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 house.

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.

Do radon levels vary by season?

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 are the symptoms of radon in your home?

Possible symptoms include shortness of breath (difficulty breathing), a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing. If you smoke and you know you’ve been exposed to high levels of radon, it’s very important to quit smoking.

How long do you have to be exposed to radon before it becomes a problem?

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.

Does radon get worse 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.

Where should you place a radon detector?

Place a radon detector in the breathing zone, 2-6 feet above the floor, and away from drafts, exterior walls, sumps, drains, windows or doors.

What states have the most radon?

Here are the 10 states with the highest 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)More items…
