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.
What is the average radon level in a 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.
What is a dangerous level of radon in a home?
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 a radon level of 2.3 safe?
FAQs: Acceptable Radon Levels. 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 it safe to live in a house with radon?
If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Over time, these radioactive particles increase the risk of lung cancer. It may take years before health problems appear. People who smoke and are exposed to radon are at a greater risk of developing lung cancer.
What is a good radon reading?
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.
What time of year is radon highest?
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.
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. Homes tend to have lower air pressure than their surroundings, which draws radon into the basement.
WHO recommended radon levels?
Based on recently completed research, the World Health Organization is recommending that homeowners take action to remediate the radon level in their home if it exceeds 100 becquerels (Bq), which corresponds to 2.7 picocuries per liter (pCi/L).
Is 10 a high radon level?
What is Considered a High Radon Level? The U.S. Environmental Protection Agency (EPA) has determined that measurements of 4 pCi/L (picocuries per liter) or higher are considered dangerous levels. This radon level is largely unsafe and is 10 times higher² than the average outdoor air levels.
Is 1.5 radon safe?
The EPA strongly recommends radon mitigation if your radon levels are above 4 pCi/L, though radon levels below 4 still pose a health risk. They recommend you consider mitigation if your radon levels are between 2 and 4 pCi/L. They are quick to point out that there is no known safe level of radon.
Is a radon level of 2.7 safe?
A “safe” level of radon listed by the WHO is anything under 2.7 pCi/L while the EPA lists anything under 4.0 pCi/L. At these levels or higher, a mitigation system is strongly suggested. In fact, radon is the primary cause of lung cancer in non-smokers and the second leading cause of all lung cancer diagnosis’.
Why do radon levels fluctuate?
Radon gas is a naturally-occurring radioactive gas found in the soil. Some weather events, like storms, typically cause radon levels in a home to rise. Other events, like heavy winds, can cause radon levels to either rise or fall. Essentially, weather events can cause your radon levels levels to either rise or fall.
Should you walk away from a house with radon?
Should you walk away from the deal? Consumer Reports says you don’t have to. 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.
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.
Can radon affect dogs?
Many pets spend on average 90-95% of their time inside. You may not know that your pet has radon poisoning until they start showing cancer-related symptoms, such as fever, abnormal swellings, coughing and lack of appetite, excessive throwing up, lameness, and breathing difficulties.
