  • Radiation Sterilisation is a cold process that uses gamma radiation for sterilisation of Healthcare Products.
  • Controlled gamma energy which is released by radioisotope such as Cobalt-60 is used for sterilisation.
  • Cobalt-60 is most preferred radioisotope as it is readily available from single nuclear reaction in reactor and also cost effective.
  • Gamma radiation is characterised by deep penetration and kills microorganism by destroying DNA structure. The process is suitable for Industrial scale sterilisation.
