What are the normal levels of radon in your home?

What are the normal levels of radon in your home?

The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels.

What level of radon is acceptable?

EPA recommends homes be fixed if the radon level is 4 pCi/L (picocurries per liter) or more. Because there is no known safe level of exposure to radon, EPA also recommends that Americans consider fixing their home for radon levels between 2 pCi/L and 4 pCi/L.

Is radon 2.2 high?

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.

What are the symptoms of radon in your home?

A persistent cough could be a sign that you have radon poisoning.

• Persistent cough.
• Hoarseness.
• Wheezing.
• Shortness of breath.
• Coughing up blood.
• Chest pain.
• Frequent infections like bronchitis and pneumonia.
• Loss of appetite.

Is it OK to live in a house with radon?

The EPA states, “Radon is a health hazard with a simple solution.” Once radon reduction measures are in place, home buyers need not worry about the quality of the air in the home. Since removing radon is relatively simple, your family will be safe in a home with a radon reduction system in place.

What time of year is radon highest?

winter
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.

What is a good radon reading?

4.0 pCi/L
According to the EPA, the maximum “acceptable” level of radon is 4.0 pCi/L, but even that level is not “safe”, per se. The EPA strongly recommends you consider radon mitigation between levels 2.0 and 4.0. For perspective, the average outdoor air level of radon is 0.4 pCi/L.

Is 1.9 radon level bad?

The U.S. EPA recommended action level for indoor radon is 4.0 pCi/L. The EPA indicates that there is little short-term risk with test results in this range (0.0 to 1.9). EPA recommends testing every 2 years.

Does opening windows reduce 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. Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.

Do all basements have radon?

Basements aren’t the only place you can find radon. This is a common assumption since radon is most commonly found in basements. Unfortunately, it’s also very wrong. Radon gas can be found anywhere in any home, not just in the basement.

Will opening windows reduce radon levels?

Does radon travel upstairs?

Radon is known to be a heavy gas. Please understand that the radon level can be significantly higher on an upper floor. Even if the radon level is lower on the first floor than say a basement radon level, it could be higher on the second floor. The only way to know is if you test.

What does Radon measure mean?

In mathematics (specifically in measure theory ), a Radon measure, named after Johann Radon, is a measure on the σ-algebra of Borel sets of a Hausdorff topological space X that is finite on all compact sets, outer regular on all Borel sets, and inner regular on open sets.

What is a dangerous level of radon?

Radon levels above 4.0 pCi/L are considered dangerous. However, government standards recommend an average level of 0.4 pCi/L to prevent virtually all possibility of harmful radon gas side effects.

What should my radon level be?

The average radon level for a home, according to the U.S. Environmental Protection Agency, is 1.3 pCi/L. The EPA does not advise individuals to consider taking action until radon levels are 2 pCi/L or greater. Therefore, one may interpret that to mean that an acceptable radon level is anything under a 2 pCi/L, especially for longer term exposure.

What is the EPA level of radon?

Radon Action Levels. The Environmental Protection Agency (EPA) and The World Health Organization (WHO) have both conducted studies and come out with a recommended Radon Action Level. The EPA has a radon action level of 4.0 pCi/L.
