Abstract
Indoor air radon concentrations can vary over four orders of magnitude. Why? These ranges occur because of the wide variations in the rate at which radon is generated from its sources (primarily soils, groundwater, and building materials), in the modes of radon’s transport through various materials, and in the means of its entry into structures. In this chapter, the sources and mechanisms of transport of radon emanating from natural and man-made environments will be discussed, focusing on those factors which result in elevated indoor radon concentrations.
