A quicker and less potentially hazardous option, rather than using X-ray sources on small areas, is to use ground-penetrating radar to do the work.
See www.structurescan.com for more information on the StructureScan II and StructureScan III systems. Or contact me for more information.

: : Post tension slabs are an everyday reality in our area (Houston). Terry is correct on the x-ray, but if the changes are near the edge of the slab (as they usually are) you can usually go outside and see the small anchor plates where the tension cables end. They have usually been covered over with some type of patch, but you can still locate them. From the plates the cables goe straight through the slab at right angles to the beam. When you've located the cables in the affected area,instead of cutting a trench and destroying cables and their surrounding concrete mass, you punch through a series of small holes from which you can tunnel under for pipes and whatever.

: Joe, Terry & John, thank you all for your quick and informative responses.
: John, I have a follow-up question. Since the changes we plan to make will be toward the middle of the slab, I assume the x-ray method will have to be used. Is this something most plumbers are equipped to do? Is it usually prohibitively expensive?
: Thank you,
