What is the highest acceptable radon level?

4.0 pCi/L
What constitutes an acceptable or 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.

What level of radon should I be worried about?

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.

What level of radon is toxic?

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

Does air purifier 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.

What is the target radon level for my home?

Radon Act 51 passed by Congress set the natural outdoor level of radon gas (0.4 pCi/L) as the target radon level for indoor radon levels. Unfortunately two-thirds of all homes exceed this level. The US EPA was tasked with setting practical guidelines and recommendations for the nation. To this end, the US EPA has set an action level of 4 pCi/L.

How do I know if my radon levels are safe?

Even with a mitigation system, the only way to know your radon levels are in a safe range is to continuously test. That’s it! You might have thought the process would be time consuming, expensive and complicated, but it’s actually pretty straightforward.

Do radon-resistant features lower radon levels?

Once the radon-resistant features have been installed and the home is completely built, make sure to perform radon testing, as the levels could still be elevated. If the radon levels are still elevated, a radon fan should be added to the system to lower the radon level.

What is the radon level of air you breathe outside?

Depending on your geographic location, the radon levels of the air you breathe outside of your home may be as high as 0.75 pCi/L.
