Quick Answer: What Should Radon Levels Be

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 is a dangerous radon level?

Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous.

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.

How bad is a radon level of 10?

Radon Risk If You Smoke Radon Level If 1,000 people who smoked were exposed to this level over a lifetime* 20 pCi/L About 260 people could get lung cancer 10 pCi/L About 150 people could get lung cancer 8 pCi/L About 120 people could get lung cancer 4 pCi/L About 62 people could get lung cancer.

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 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.

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 2.3 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 a radon level of 2.4 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.

Is 5.3 radon level bad?

Levels of 4 pCi/L or higher are considered hazardous to your health, and you need to take action against radon if your levels are higher than 4 pCi/L. Still, radon levels less than four pCi/L can pose a risk and, in many cases, can be reduced, but it’s harder 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.

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.

What is a safe level of radon UK?

There is no known “safe” level of radon, but the lower the concentration you are exposed to, the lower the risk to your health. Current advice from Public Health England is that “for levels below 100 Bq/m3, your individual risk remains relatively low and not a cause for concern.

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.

What causes radon to spike?

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.

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.

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.

What is the most accurate radon test?

The best radon test kit is the AccuStar Radon Test Kit. This kit is easy to use, accurate and includes quick-arriving results.

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%.
