Description:
The chapter is for inclusion in a textbook, Environmental Radon, for graduate students. It gives a flavor of what radon mitigation entails, rather than being a detailed handbook treatment of the subject. It emphasizes the removal or reduction of soil-gas-borne radon (the major source of radon in most houses) and briefly describes the following methods of reducing/removing indoor radon: natural ventilation; forced air ventilation; forced air ventilation with heat recovery; reducing entry points (sealing); venting radon from the soil surrounding a house by drain-tile soil ventilation, sub-slab ventilation, or wall ventilation; reducing pressure differentials; removing radon from water; and air cleaning. It gives background information on house construction types, the significance of weather phenomena, and the significance of the stack effect in elevating indoor radon levels.
