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 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.
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.
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.
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.
What is an unsafe level of radon?
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.
How long does it take for radon to affect you?
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. Early signs and symptoms of lung cancer may include: persistent cough.
How worried should I be about radon?
Radon Is a Cancer‑Causing, Radioactive Gas But it still may be a problem in your home. When you breathe air containing radon, you increase your risk of getting lung cancer. In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today.
What causes high radon levels?
When radon is confined to enclosed or poorly ventilated spaces, it can accumulate to high levels. Radon levels are generally highest in basements and crawl spaces because these areas are nearest to the source and are usually poorly ventilated.
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.
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 running HVAC reduce radon?
Based on the results it was concluded that an active ventilation system successfully reduces radon.
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%.
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.
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.
Is radon level of 2 safe?
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.
Can radon make you feel tired?
Additional, long-term symptoms of radon gas exposure include loss of appetite, weight loss, and fatigue. It’s important to be aware of the symptoms above because not only do they indicate symptoms of radon exposure, but consistent exposure to radon can also lead to lung cancer.
Is radon gas worse in summer or 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.
What are 5 facts about radon?
Here are a few facts about radon, and what you can do to help keep your family healthy and safe. Radon is radioactive. Radon is a naturally occurring radioactive gas. Radon causes cancer. No immediate symptoms. You must test for radon. Radon is present indoors and outdoors. Radon can build up in any building.
What causes radon in a house?
It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up. Radon from soil gas is the main cause of radon problems.
How do you reduce radon in your home?
More Ways to Take Action Stop smoking and discourage smoking in your home. 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.
What is a 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 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.
