The U.S. EPA does not recommend sealing radon entry routes as stand-alone radon reduction technique because:

Answer 1

Sealing radon entry routes alone may not effectively reduce radon levels in a building. A combination of radon reduction techniques should be used.

Step-by-step explanation:

The U.S. EPA does not recommend sealing radon entry routes as stand-alone radon reduction technique because sealing entry routes alone may not effectively reduce the radon levels in the building. Radon can enter buildings through various pathways such as cracks in floors and walls, construction joints, and gaps in suspended floors. Sealing these routes may not be sufficient to lower the radon levels to a safe level. It is important to use a combination of radon reduction techniques, such as sealing entry routes and improving ventilation, to effectively reduce radon levels.
