Hoe does Radon enter the home? - CORRECT ANSWER✔✔-Radon gas
| | | | | | | | | |
moves through the ground due to air pressure differentials in the home,
| | | | | | | | | | | |
and up into the home through cracks or other openings in the

foundation. Can also enter through well water and some building
| | | | | | | | | |
materials.
