gamma irradiation facility

Irradiation is a process in which the products, such as foods and medical instruments …, in form of packages are exposed to certain controlled intensity of ionized radiation in a determined duration to achieve desired effects.

Main applications of gamma irradiation are as follows:

- Irradiation of foods and agricultural products in order to remove parasites, bacteria, and fungus to extend shelf life, sterilization, and modified seeds.  

- Sterilization of medical equipment and cosmetics including drugs, syringes, gauze sterile, and other disposable medical instruments.

- Material modification including polymerization, cross-linking, and coloring gemstones.     

More than 200 gamma irradiation facilities throughout the world (55 countries) are now operating and most of which are used for sterilization of medical devices.
Syringes, surgical gloves, sterilized masks, clothes, adhesive plasters, wound dressings, baby glass bottle heads, artificial joints, surgical instruments, gauzes used for cleaning blood, blood transfer equipment, suction-related devices, some eye lenses, food packages, cosmetics raw materials, and corks can be sterilized by gamma radiation.  
A gamma irradiation facility as an industrial unit consists of irradiation room, shielded container of radioactive sources (dry or wet pools), source rack movement mechanism, shielding around the irradiation room, control room, totes, conveyor system, shielding maze, safety interlocks, and products loading, shifting and unloading sections.
