Using gamma radiation from Cobalt 60 is used to sterilise syringes:
Gamma rays, emitted from cobalt-60, are similar in many ways to microwaves and X-rays. Gamma rays delivered during sterilization break chemical bonds by interacting with the electrons of atoms, which would kill anything made of atoms (which is everything). And although gamma rays are highly effective in killing micro-organisms, they leave no residues nor have sufficient energy to impart radioactivity. Also the gamma rays can be used over and over again, with hardly any time preparing them, as would be the case in steam st…
