radioactive fluid is typically injected into your body, allowed to
circulate for awhile, then scanners are used to determine what portions
of the body have absorbed the fluid - typically cancer tumors etc... The
scanning itself has no radiation or other harmful effect, and the
radioactive fluid will have largely died away within just a few hours.
Generally speaking, quite safe. Nothing like X-Rays (which can do
permanent damage.. MRIs are also quite safe.
See http://www.radiologyinfo.org/en/info.cfm?pg=PET&bhcp=1#5
Probably want to thoroughly flush your system with lots of clean water
afterwards, anything to get good fluid exchange going. And don't plan on
going thru the airport for a day or two just in case..
