Glow-in-the-dark bodyparts

  I just dislike all the trouble of taking just one X-ray in hospitals...all the waiting etc.
  Why not have an edible, non-toxic, harmless solution where patients just have to drink it down & stand in a dark room......Ta-da!The patient glows! Different colored liquids for "lighting up" different cell types, e.g. Blue for bone cells, Green for nerve cells.
  P.s: I know it sounds impossible to create it, as radiation can be harmful, even fatal. But as time goes, let's see if we can make non-harmful radiation...
