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.Feb 15, 2017
How long does it take for radon to be harmful?
There are no immediate signs or symptoms from breathing in background radon. Repeated exposure over time — around 20 years — can lead to cancer development, especially if you are also a smoker. Symptoms of lung cancer may include: Chest pain.

What is an extremely high level of radon?
Fix the home if the radon level is 4 picocuries per liter (pCi/L) or higher. Radon levels less than 4 pCi/L still pose a risk and, in many cases, may be reduced. Take steps to prevent device interference when conducting a radon test. EPA estimates that radon causes thousands of cancer deaths in the U.S. each year.
Is a radon level of 3.2 safe?
However, EPA believes that any radon exposure carries some risk—no level of radon is safe. Even radon levels below 4 pCi/L pose some risk, and you can reduce your risk of lung cancer by lowering your radon level.
Is it OK to live in a house with radon?
Radon is the second leading cause of lung cancer after cigarette smoking. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Having your home tested is the only effective way to determine whether you and your family are at risk of high radon exposure.
Does opening windows help with 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. Homes tend to have lower air pressure than their surroundings, which draws radon into the basement.

How serious is radon in a home?
Radon is a radioactive gas emitted naturally from the ground. However, when radon gets trapped indoors—after entering a home through joints in walls, basement floors, foundations and other openings—it may concentrate at dangerous levels. And exposure to high levels of radon can cause lung cancer.

Should I walk away from a house with radon?
Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home. It’s actually pretty easy to remove radon, and it’s not that expensive,” Consumer Reports Home Editor Paul Hope said.

Do air purifiers help with 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 I get rid of radon naturally?
Other Ways to Reduce Radon
- Increase air flow in your house by opening windows and using fans and vents to circulate air. …
- Seal cracks in floors and walls with plaster, caulk, or other materials designed for this purpose.
How do you eliminate radon?
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.
How long does it take for radon to dissipate?
Radon gas is a radioactive gas that you cannot see, smell, or taste. It’s produced as a byproduct as certain radioactive elements decay. The most common type of radon has a half life of 3.8 days, which means half of the gas is left 3.8 days after it formed.
Are radon detectors reliable?
Based on the requirements of these two programs, one could generalize that short-term or long-term radon detectors that have passed one of these performance tests have an accuracy of about 25% or possibly better.

Is radon higher in winter?
Since radon levels are likely to be higher during the winter you can expect the level to not rise much higher during the rest of the year. You are also most vulnerable to radon during the winter since you will be inside for much of it and breathing the same reheated, recirculated air.

Does room temperature affect radon testing?
Temperature. Outside temperature can affect your radon levels.
What season is radon the highest?
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.
Does a dehumidifier reduce radon?
No, buying a dehumidifier will not make radon go away. Research conducted by the US Environmental Protection Agency (EPA) has clearly disproved this idea.

Does radon get worse over time?
We are asked about this all the time and the answer is yes. As the earth and soil under a house changes with time, it can produce higher levels of radon gas. Also, as your house ages, the radon that accumulates in the house may increase.

How long does it take for radon to build up in a house?
Radon does not build up in a residence over time due to its short half-life (3.8 days). Many conditions could affect the measured radon concentration over time in a residence.

Can radon levels go up and down?
Radon levels are constantly changing – hourly, daily, and seasonal fluctuations are all common. If you have tested multiple times and received back differing results, don’t be too alarmed – this is common!
