          Industrial Applications of Radiation Sources



          Radiation Processing Facilities (RPF)
          RPF  includes  Gamma  Radiation  Processing  Facility  (GRAPF)/  Gamma
          Irradiators and Electron Beam Accelerators are used mainly for radiation
          processing of food (i.e. inhibiting sprouting, delay in ripening, microbial
          decontamination, insect disinfestation, shelf-life extension etc.),
          sterilisation of healthcare products and crosslinking of polymers in cable
                                                          15
                                                                 60
          industries. The activity range is about few PBq (eg.10 Bq) of  Co.



                                                 Industrial Accelerators Radiation Processing Facility (IARPF) operated
                                                 in electron mode of energy range from 1.5 to 3 MeV and are mainly
                                                 used for cross linking of polymers. One of the benefits of accelerators
                                                 is that, unlike radioactive sources, it produces radiation only when
                                                 they are energized.
                                                 The RPFs are of high radiation hazard potential.


          Research Accelerators

          Research Accelerators or Particle Accelerator Research Facilities (PARF) are generally installed in academic
          & research institutions and catering to the research needs of various fields of high energy physics, material
          science, radiation studies etc. Accelerators installed in our country
          operated in the energy range from a few hundreds of keV to GeV.
          The hazard associated with the facilities also diverse in nature and
          ranges from very high-to-moderate hazard potential. The radiation
          hazard potential of an accelerator mainly depends on the type of
          ion(s) accelerated, type of accelerator and beam parameters (e.g.
          energy & current, target system). Besides radiation hazard, other
          industrial hazards such as electrical, mechanical, RF, magnetic,
          cryogenic etc. are also present in an accelerator facility.
