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 normal radon levels at 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 the safe level of radon?
What is a safe level of radon? Any radon level poses some health risk and it is not possible to reduce radon to zero. The best approach is to lower the radon level as much as possible. The Environmental Protection Agency (EPA) has set the action level at 4 pCi/L (picocuries of radon per liter of air).
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.
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.
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.
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’.
Is a radon level of 1.5 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 radon level 2.1 safe?
Radon is found in outdoor air and in the indoor air of buildings of all kinds. 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.
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.
How do you eliminate radon?
Other radon reduction techniques that can be used in any type of home include: sealing, house or room pressurization, heat recovery ventilation and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction.
Are radon detectors accurate?
The National Radon Safety Board evaluates radon measurement devices in cooperation with the US Environmental Protection Agency. It requires that the individual relative error of each device be less than or equal to 20.0% and that the precision error of all devices be less than or equal to 20.0%.
Does running HVAC reduce radon?
Based on the results it was concluded that an active ventilation system successfully reduces radon.
Does an HRV help with radon?
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.
Does radon give you a headache?
The only known health effect of radon is an increased risk of lung cancer. Radon does not cause any warning symptoms like headaches, nausea, fatigue, or skin rashes.
What are symptoms of radon poisoning?
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.
Will opening the basement windows before a radon test lower the results?
Unfortunately, no, opening the windows does not reduce radon. It is not a gas that will just permanently escape the home like smoke from something burning in the oven. The radon may seem to leave when the windows are open, but as soon as they are closed, it is back.
Does a dehumidifier help with 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.
