Gamma rays are highly energetic, ionized particles radiated by the Sun. They are deadly to all forms of cellular life - limited exposure to them would probably result in a person contracting cancer because they cause mutations at the molecular level. Exposing surgical instruments to gamma rays would probably result in the instruments absorbing and then re-radiating these particles - in other words the instruments would become radioactive.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
