If radon comes from the ground then how does it get into upper levels of a building? In some cases, it emanates from the concrete and other building materials used to construct condos; in others, it moves from the ground to upper floors via elevator shafts, stairwells and venting shafts. No mater what it is a good idea to test any space for radon that is occupied.
