What is an unsafe level of radon?
4 pCi/L
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 the highest acceptable radon level?
4.0 pCi/L
FAQs: Acceptable Radon Levels. 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 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 percentage of radon is acceptable?
Depending on the country, acceptable radon levels vary. A generally accepted action level established by the World Health Organization, the WHO, is 100 Bq/m3, or 2.7 pCi/L. Homes or structures measuring higher are advised to take remedial action to lower radon levels.
Is it OK to live in a house with radon?
However, because radon isn’t safe at any level, they also suggest treating homes with radon levels between 2 and 4 pCi/L. According to the EPA, the average radon gas concentration in a home is about 1.3 pCi/L, which does not pose an appreciable risk to most residents living in the house.
Should you walk away from a house with radon?
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. It’s actually pretty easy to remove radon, and it’s not that expensive,” Consumer Reports Home Editor Paul Hope said.
What level of radon needs action?
The Government advise that remedial action should be taken in any residential property with an average annual radon level of 200 Bq/m3 or more. This is referred to as the Action Level.
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.
How do I get rid of radon naturally?
Other Ways to Reduce Radon
- 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.
Are home radon test kits accurate?
“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. ScienceDaily, 4 December 2019.
Does opening windows get rid of radon?
As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.
