Quick Answer: At What Level Should You Mitigate Radon?

Is a radon level of 4.5 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.

The EPA estimates that a radon removal system costs about $1,200 for an average house..

Is radon higher in summer or winter?

This is because in well-ventilated dwellings the radon can easily escape out. Moreover, the results reveal that the seasonal variation of indoor radon shows high values in winter and low values in summer.

How long does radon take to cause cancer?

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.

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.

Does sealing a basement floor reduce radon?

Sealing the basement floor can help reduce the amount of radon entering the home. … Sealing all cracks and applying non-porous, thick epoxy coatings (over 10 MILS dry film thickness) would be a better step.

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.

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.

Does finishing a basement reduce radon?

Several years after finishing the basement, you might find that the radon level has increased above the EPA’s action limit (4 pCi/L) and must be reduced to make the house marketable. But once the basement has been finished, you have to get a fan-based radon mitigation system ($1,200 on average).

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.

How do you reduce radon levels in a basement?

An active radon sump, fitted with a fan, is the most effective way to reduce indoor radon levels. Sumps work best under solid floors and under suspended floors if the ground is covered with concrete or a membrane. Occasionally, passive sumps without a fan may reduce radon levels.

Can I install my own radon mitigation system?

In most cases, pros charge about $1,500 to install a radon mitigation system, but you can do it yourself for only about $500 in materials. So if you’re fairly handy and have some carpentry, plumbing and electrical skills, you can install your own system in a weekend and save yourself a thousand bucks!

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.

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.

How do you mitigate radon?

Mitigation of radon in the air is accomplished through ventilation, either collected below a concrete floor slab or a membrane on the ground, or by increasing the air changes per hour in the building. Treatment systems using aeration or activated charcoal are available to remove radon from domestic water supplies.

Does seller have to mitigate 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 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.

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 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.
