What are the most common ways that radon gas can enters a home?

Answer: Radon typically enters a building from soil gases through the foundation. However, in some cases, radon is present in water from wells, which can disperse into the air. Further, radon can emanate from certain building materials, so even though the primary entry mechanism is from soil gas migration through the foundation and is typically concentrated at the lowest level, emanation can be present from building materials even in high rise buildings.

Answer: When radioactive rocks and soil break down, they release radon gas. That gas can enter buildings through: - Construction joints. - Cracks in walls or floors. - Gaps in foundations. - Openings near pipes or wires. Less commonly and in smaller amounts, radon can be released from: - Building materials made from natural substances, such as concrete, wallboard and granite countertops. - Water, especially water that comes from underground wells.

Answer: Voids and openings in basement floors and walls as well as open (uncovered) sump pits.

Answer: cracks in the floor, sump pump pits, thin concrete slabs

Answer: Open cracks in the Slab such as the sump pit

Answer: Through the gaps and cracks in a foundation

Answer: The soils below the structure. If the structure has a concrete slab, the gas enters through any voids. If the structure if over a crawlspace, the gas enters through any voids in the vapor barrier.

Answer: cracks in basement flooring.

Answer: Concrete floor, dirt floor, cracks in the concrete floor, areas where the floor meets the walls and through the sump crock.

Answer: The gas enters through any crack, hole sump area, crawl space, etc.

Answer: Radon enters a home through areas of low pressure. It can enter your home through cracks in a foundation , sump pits and through your water supply.

Answer: Foundations cracks, Open drainage (sump pump pit), water proofing systems, dirt crawl spaces, ground water

Answer: The most common ways radon gas enters a home is through openings in a home, cracks in the floor and walls.

Answer: Thru cracks in the foundation , sump pumps ,sewer lines.
