Question: Is A Radon Level Of 5 Bad?

Is a radon level of 4.9 Dangerous?

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..

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.

How much does it cost to fix high radon levels in home?

The cost of fixing a home generally ranges from $800 to $2500 (with an average cost of $1200). Your costs may vary depending on the size and design of your home and which radon reduction methods are needed. Hundreds of thousands of people have reduced radon levels in their homes.

Are radon concerns overblown?

Radon revisited. The early warnings may have been overblown, but research since has shown that lung cancer risk from the gas is real. … Radon may not be tobacco, but health officials still rank it as the second-leading cause of lung cancer in the United States.

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.

Can you get rid of radon?

There’s no single method that fits all radon removal system needs. Common techniques include: Sub-slab depressurization, where suction pipes are inserted through the floor or concrete slab into the concrete slab below the home. A radon vent fan then draws out the radon gas and releases it into the air outside.

Can radon levels 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.

Is radon really a big deal?

Now, according to the EPA, the WHO, and many other big public health organizations, radon is second only to cigarette smoking as a leading cause for lung cancer. The EPA says radon gas causes 21,000 deaths every year. … But critics say scientists can only prove that radon is carcinogenic at high doses.

What level of radon causes cancer?

Your risk of lung cancer increases substantially with exposure to higher radon levels. Lung cancer risk rises 16% per 2.7 pCi/L increase in radon exposure. World Health Organization, 2009 studies show that radon is the primary cause of lung cancer among people who have never smoked.

Is radon a scare tactic?

The radon scare was set off because of lung cancer in early uranium miners. … Residential radon is harmless. Exposure limits set by EPA with LNT theory also impair progress in medicine and nuclear power. EPA rules ignore science, biology, and observed low-level radiation health effects.

Is high radon a deal breaker?

If your test comes back registering high levels of radon gas, you should then consult professionals for testing and possible mitigation. Selling a house with high radon levels isn’t impossible, and it’s not a definite deal-breaker if your dream home tests high.

How do you fix high radon levels?

A heat recovery ventilator (HRV) or energy recovery ventilator (ERV) can be installed to increase ventilation, which will help reduce the radon levels in your home. An HRV increases ventilation by introducing outdoor air as it uses the heated or cooled air being exhausted to warm or cool the incoming air.

Where is Radon most common?

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.

How long does it take to get cancer from radon?

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.

How dangerous is a radon level of 7?

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.

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.

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 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.

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.”

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.
