My understanding on why this is, is because in New England there's a lot more granite in the ground. Granite is particularly annoying in that respect because the trace amounts of, i think, uranium and radium that the rock concentrated when it was formed will give off the radon gas when they decay.
- eichin 3y agoand that can mean high outdoor radon levels... a home inspector back in early 2000 told me about a seller sneaking back in and opening basement windows to attempt to pass a radon test (sensors left in the basement over the weekend.) The inspector caught it but let the test run to completion - at which point it failed anyway because the adjacent "forest with exposed granite rocks" was a fine natural radon source...
