The series passes ultimately through radium directly to radon, which, in turn, decays to other elements. Of all the elements produced in the uranium decay series, only radon is a gas.
Because radon is a gas, it easily drifts upward through the ground to the Earth’s surface. How much of it reaches the surface depends on the uranium content of the underlying earth materials together with their depth and permeability (that is, the presence of fractures and interconnected pore spaces that act as conduits for radon). Radon will enter the lowest level of a building using whatever pathways are available. For structures with basements or slab-on-grade foundations, the entry points include (1) cracks and pores in floor slabs, walls, and floor-wall joints; and (2) openings around sump pumps, floor drains, and pipes penetrating floors and walls. Structures with a crawl space between the ground and lowest floor level may be less vulnerable to […]
