WebRadon is a colourless, odourless, radioactive gas that occurs in rocks and soils, some building materials and water. The ground is the most important source as radon can seep out and build up in houses and indoor workplaces. The highest levels are usually found in underground spaces such as basements, caves and mines. WebStep 2: Dig out under the slab. A drill-powered auger is used to dig a small pit below the slab. If the layer below is granular, such as gravel, only a small pit is needed. If the soil is dense, a larger pit is needed to increase the area the fan will pull from. Dig this by first loosening the soil under the slab then vacuuming it out.
