Is radon an issue in Alaska even with sparse population?

Yes. Several Alaska regions have measured homes above 4.0 pCi/L, so testing is still recommended in occupied homes.

Do slab homes in Alaska need testing?

Yes. Slab-on-grade homes can still draw radon through slab joints and utility penetrations.
