- 1 This practice outlines the installation qualification pro-gram for an irradiator and the dosimetric procedures to be followed during operational qualification, performance quali-fication, and routine processing in facilities that process food with ionizing radiation from radionuclide gamma sources to ensure that product has been treated within a predetermined range of absorbed dose. Other procedures related to operational qualification, performance qualification, and routine process-ing 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 ASTM Guides F 1355, F 1356, F 1736, and F 1885). Note 1—Dosimctry is only one component of a total quality assurance program for adherence to good manufacturing practices used in the production of sale and wholesome food. Note 2—ISO/ASTM Practice 51431 describes dosimetric procedures for electron beam and X-ray (brcmsstrahlung) irradiation facilities for food processing. 2 For guidance in the selection and calibration of dosim-etry systems, and interpretation of measured absorbed dose in the product, see ISO/ASTM Guide 51261 and ASTM Practice E 666. For the use of specific dosimetry systems, see ASTM Practices E 1026 and E 2304, and ISO/ASTM Practices 51205. 51275, 51276, 51310, 51401, 51538, 51540, 51607, 51650, and 51956. For discussion of radiation dosimetry for gamma-rays and X-rays also see 1CRU Report 14. 3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.

电子顺磁共振波谱仪丨辐射剂量相关检测应用
钠钙玻璃：钠钙玻璃进行剂量重建研究，分别使用3种方法对样本实施了剂量重建，结果显示g值法在0~10Gy内辐射剂量测定与重建中具有较高的应用价值，但仍需进一步研究该方法的信号稳定性和温度依赖性。总结：EPR可直接监测样品中的顺磁分子，在较短时间内完成辐射剂量重建。测试过程可通过X-波段的EPR波谱仪，该设备可应用于肿瘤放射治疗领域。...
