Scope

Scope: This standard specifies the content and procedures of dose measurement involved in the installation, operation, performance evaluation, and routine processing of food irradiation devices, as well as other related procedures. This standard applies to food irradiation processes using gamma rays generated by 60Co or 137Cs radiation sources, and electron beams or X-ray irradiation devices produced by electron accelerators. Main technical content: This standard comprises a preface and 13 main chapters. **Preface**: Provides information on the standard's preparation and drafting units, etc. **1. Scope**: This standard specifies the content and procedures of dose measurement involved in the installation, operation, performance evaluation, and routine processing of food irradiation devices, as well as other related procedures. **2. Normative Reference Documents**: Lists the relevant normative documents referenced in this standard. **3. Terms and Definitions**: Defines 31 terms related to food irradiation doses, dose measurement, irradiation devices, processing parameters, installation verification, and performance evaluation, based on the scope and requirements of this standard. **4. General Principles**: This section outlines the overall requirements for the minimum effective dose, maximum acceptable dose, dose distribution, and dose measurement in food irradiation. **5. Irradiation Devices**: This chapter describes the components of irradiation devices, including radiation sources or beam devices and their transmission methods. **6. Dose Testing Systems**: This chapter presents the composition, selection principles, and calibration requirements of dose measurement systems. **7. Processing Parameters**: This chapter separately presents the absorbed doses of radiation sources and beam devices and their respective processing parameters. **8. Installation Verification**: This section outlines the content and purpose of installation verification, spe
