ISO/ASTM 51431 describes dosimetric procedures to be followed in facility characterization, process qualification and routine processing for electron beam and bremsstrahlung irradiation facilities for food processing in order to ensure that the product receives an acceptable range of absorbed doses. Other procedures related to facility characterization, process qualification and routine product processing that may influence and be used to monitor absorbed doses in the product are also discussed.
The electron energy range covered in this practice is from 0,3 MeV to 10 MeV. Such electrons can be generated in continuous or pulse modes.
The maximum electron energy of bremsstrahlung facilities covered in this practice is 10 MeV. A photon beam can be generated by inserting a bremsstrahlung converter in the electron beam path.
