Freeze-Protected Exterior Radon Fan Housing
Insulating exterior radon fan enclosures and heat-tracing exhaust lines to prevent ice blockages during sub-zero winters.
Uranium-rich pegmatite intrusions, Roan Mountain amphibolite, and intense winter heating drafts in Yancey, Mitchell, and Avery draw high radon concentrations into homes.
Pegmatite formations containing uraninite and feldspar concentrate radon emissions along fault lines and mountain hollows.
Staged out of Burnsville and Spruce Pine, technicians carry heavy core drills, sub-zero pipe insulation, and all-weather exterior fan enclosures.
