Question: Is High Radon A Deal Breaker?

Is it safe to buy a house with high radon levels?

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.

Even in houses with extremely high radon levels, you can expect a drop to levels considered safe..

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.

What time of year is radon 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 are the symptoms of radon exposure?

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.

Is it safe to live in a house with radon mitigation?

If a house you’re interested in tests positive for high levels of radon, odds are, other houses in the area are likely to have high levels as well. Since removing radon is relatively simple, your family will be safe in a home with a radon reduction system in place.

Does buyer or seller pay for radon mitigation?

“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.” 7.

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.

Is a radon level of 5 bad?

The average global outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L. For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon exposure, lung cancer risk rises 16%4. … As radon gas can accumulate indoors, it is important to monitor daily.

Does Radon only stay in the basement?

Radon is completely odorless as well as being invisible. Because it is often found unexpectedly in basements, some people mistakenly believe that it only occurs in basements. Not to be forgotten, homes built on a slab are also at risk for high radon levels. …

Does finishing basement reduce radon levels?

Radon mitigation in finished basements: Most newer homes would have a vapour barrier below the slab, though likely not well-sealed. Some homes will have none, but in either case, concrete in fairly good condition should provide enough of an air barrier to contain radon below it.

What happens if radon levels are high?

Exposure to high levels of radon in indoor air results in an increased risk of developing lung cancer. The risk of cancer depends on the level of radon and how long a person is exposed to those levels. Exposure to radon and tobacco use together can significantly increase your risk of lung cancer.

Should I not buy a house with radon?

Radon can seep into any home that is in contact with the ground. It is undetectable unless you perform a radon test. It is the second leading cause of lung cancer and according to the EPA and CDC, it kills more than 20,000 annually. It is not something you want in the home you are buying.

At what level should you mitigate radon?

EPA recommends fixing your home if the results of one long- term test or the average of two short- term tests show radon levels of 4 pCi/L or higher. With today’s technology, radon levels in most homes can be reduced to 2 pCi/L or below. You also may want to consider fixing if the level is between 2 and 4 pCi/L.

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.

Is it hard to sell a house with radon?

Fortunately, it’s not hard to sell a house with radon, provided that you alert potential buyers and mitigate the problem, say Brian Thomas, a top real estate agent in the Denver, Colorado area, with 16 years of experience. “For as much fear and uncertainty as radon causes, there’s an easy fix.”

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.

How do you fix high radon levels in your 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.
