Is a radon level of 5 high

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 are really bad radon levels?

No level of radon is safe. The United States EPA has established the radon level of 4.0 picocuries per liter to be the action level for radon gas in homes. Meaning, take action to reduce radon levels that are greater than four picocuries per liter. But consider taking action if radon levels are between 2-4.

What is an acceptable radon level in a house?

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.

How do you eliminate radon?

Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.

Will radon go away?
