This practice outlines dosimetric procedures to be followed in irradiator characterization, process qualification, and routine processing of food with ionizing radiation from isotopic gamma sources to ensure that all product has been treated within a predetermined range of absorbed dose.her procedures related to irradiator characterization, pro-ss qualification, and routine processing that may influence absorbed dose in the product are also discussed. Information about effective or regulatory dose limits for food products is not within the scope of this practice (see Guides F 1355 and F1356). Note 1—Dosimetry is only one component of a total quality assurance program for adherence to good manufacturing practices used in the production of safe and wholesome food. Note 2—Practice E 1431 describes dosimetric procedures for elec-tron beam and bremsstrahlung (X-ray) irradiation facilities for food processing.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; Practices E666, E668, E 1026, E 1205, E 1275, E 1276, E 1310, and E 1401. For discussion of radiation dosimetry for gamma rays and X-rays see ICRU Report 14. 3 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 appro-safety and health practices and determine the applica-of regulatory limitations prior to use.
