Scope

1.1 This practice describes dosimetric procedures to be followed in characterizing, qualifying, and operating electron beam and bremsstrahlung irradiation facilities for food processing. Other procedures related to facility characterization, product qualification, and routine processing are also discussed.

1.2 The electron energy range covered in this practice is from 0.1 MeV to 10 MeV. Such electrons can be generated in continuous or pulse modes.

1.3 The maximum photon energy covered in this practice is 5 MeV. A photon beam can be generated by inserting a bremsstrahlung converter in the electron beam path.

1.4 For guidance in the selection, calibration, and use of specific dosimeters, and interpretation of absorbed dose in the product from dosimetry measurements, see Guide E1261, Method E1026, and Test Method E1205. For discussion of radiation dosimetry for X rays and gamma rays, see ICRU Reports 14 and 17, and for pulsed radiation, see ICRU Report 34. For application of dosimetry in the characterization and operation of a gamma irradiation facility for food processing, see Practice E1204, which also contains material relevant to the operation of an accelerator facility operated in a bremsstrahlung mode.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
