Question: What Is An Acceptable Radon Level

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 considered high levels 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.

Is radon 2.7 Bad?

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 3.6 radon bad?

Long-term radon testing revealed that the radon level near our countertops is very low but the level in the basement is 3.6 picocuries per liter. The EPA also says that radon levels below that can still pose a health risk and recommends that you consider remediation when the level is above 2 and under 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.

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.

Is 2.5 a safe radon level?

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. Professional mitigation is the only reliable way to reduce elevated radon readings.

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.

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.

Is a radon level of 5 bad?

The only safe level of radon is zero. Radon levels measure in picocuries per liter, or pCi/L. 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.

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 reduce 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.

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.

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 accurate are radon tests?

“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.

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 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 causes radon levels to 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.

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.

Do air purifiers help with radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.
