Sterilization is a process by which all form of microbial life is inactivated.
Gamma radiation is very effective in inactivating micro-organisms, the probability of any microbial survival can be expected less than one in million at a dose of 2.5 Mrad. The sample for trial can be sent to SARC to check the bio-burden before and after radiation. Since sterilization is effected after final packaging, product sterility is retained indefinitely provided the package is undamaged. This is a continuous, fully automated process with a single parameter, namely time of exposure to be controlled, steam sterilization and ethylene oxide sterilization, apart from being batch processes, require more than one parameter to be controlled. Almost all medical products which come under C and C1 schedule and other schedules are commonly sterilized by radiation.
