What are high radon levels?

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. Once installed, a follow-up radon test is done.

Can radon be removed from water?

Radon can be removed from water by using one of two methods: Aeration treatment – spraying water or mixing it with air and then venting the air from the water before use, or. GAC treatment – filtering water through granular activated carbon. Radon attaches to the carbon and leaves the water free of radon.
