    CAN SLAB ON GRADE OR WALK OUT BASEMENTS HAVE HIGH LEVELS OF RADON?

    For radon to enter and build up in a house, all that is required are some cracks, spaces, gaps in the foundation, radon in the soil, and the inside air warmer than the outside air. As warm air rises in the house and is released out the top via the chimney, attic, appliance’s emissions, and exhaust vents. As long as these variables are present, radon will exist in every building, regardless of whether the house has a slab on grade, crawlspace or walk out basement. This is especially true during the winter season when the temperature differential is big, the stack effect is more relevant, and all the windows and doors are closed or tightly sealed.
