Radon Series 3 What is Radon

Radon can enter a home from the soil via cracks in floors and walls, floor drains, sump pumps and construction joints. Radon is usually more concentrated in basements and ground floor rooms that have contact with the soil. The design, construction details and building materials used can affect the pathways and sources that can draw radon into a home. Domestic water contaminated with radon can also contribute to indoor radon levels. Fortunately, water radon levels will contribute significantly less that soil radon levels to the indoor radon concentration.
