"My feeling is that the chance of our surviving into the twenty-first century as working civilization is less than fifty percent but greater than zero."
- Isaac Asimov

Bacteria-Destroying Radiation  
  A special beam that created a sterile field for operations.  

Now he began arranging his instruments on a portable worktable. As the last of the cold-pack was drained off by the suction tendrils, Parsons flicked on a high-frequency field and placed the potentials on each side of the cube. The terminals hummed and glowed as the field warmed. Now the inert body was within a zone of bacteria-destroying radiation.
From Dr. Futurity, by Philip K. Dick.
Published by Ace Books in 1960

Ultraviolet germicidal irradiation is a sterilization method that uses short-wavelength ultraviolet light to destroy micro-organisms. UV has been known to have these properties since the turn of the century (19th, that is).
