A less common technique functions successfully by reducing air pressures within tooth cavities of exterior and also demising walls where radon emitting from building materials, usually cinder blocks, gathers.

Radon reduction training in Florida does not include problems connected with mechanical air flow systems, such as high interior moisture, mold and mildew, moldy smells, residential property damages or health and wellness effects of human occupation in high moisture of musty environments [citation needed ]
