PNRI operates the following irradiation facilities: the Cobalt-60 Multipurpose Irradiation Facility (MIF), the Gammacell-220 and the Electron Beam Irradiation Facility (EBIF). PNRI extends the use of these facilities to various clients for food irradiation, medical products sterilization and for research purposes.

MULTIPURPOSE IRRADIATION FACILITY (MIF) and GAMMACELL-220
MultiPurposeIrrad

Gamma radiation coming from the cobalt-60 source in this facility  can kill or prevent the multiplication of microorganisms in food, medical products, cosmetic raw materials and packaging. Radiation can delay sprouting of bulbs like onions and garlic or the ripening of fruits or reduce infestation of stored agricultural products. It also increases the incidence of genetic changes in plants, accelerating the development of useful mutants.

These useful effects can be achieved by exposing the materials /products to a calculated dose of gamma radiation inside the well- shielded Multipurpose Irradiation Facility (for bulk irradiation) or in the Gammacell-220  (for small volume of samples).

Before routine exposure of materials/products to be irradiated, tests are first made to determine the suitability of the materials to gamma radiation and to ascertain the appropriate radiation dose depending on the purpose of irradiation , i.e. for sterilization, reduction of microbial load or decontamination, induction of mutations or changes in the chemical/physical properties of the material.

ELECTRON BEAM IRRADIATION FACILITY  (EBIF)
ElectronBeam

As the next step in PNRI’s use of irradiation technologies, the 2.5 MeV electron beam (EB) facility is the first of its kind in the country  intended for full-scale research and development and semi-commercial EB services.

The newly established EB facility opens more applications of radiation such as improving the quality of semiconductors, automobile parts/tires, O-rings, wires and cables and production of nanomaterials, among others. This can also be used in radiation sterilization of medical devices,  food irradiation, radiation crosslinking, degradation or grafting of polymers and for surface curing.
