ISO 13304-1:2020 标准是一项关于电子顺磁共振（EPR）光谱技术在回顾性剂量测量中的最小标准。该标准适用于使用EPR技术进行离子辐射剂量测量的实验室和机构。EPR技术是一种基于电子自旋共振的技术，可以用于测量辐射剂量。该技术可以用于回顾性剂量测量，即在辐射事故或其他辐射暴露事件后，通过测量人体或其他生物体内的辐射剂量来评估辐射暴露的程度。

该标准规定了EPR技术在回顾性剂量测量中的最小标准，以确保EPR技术的准确性和可靠性。该标准包括以下内容：

1. EPR技术的基本原理和应用范围；
2. EPR技术在回顾性剂量测量中的应用；
3. EPR技术的仪器和设备要求；
4. EPR技术的样品制备和测量要求；
5. EPR技术的数据分析和处理要求；
6. EPR技术的质量保证和质量控制要求。

该标准的实施可以提高EPR技术在回顾性剂量测量中的准确性和可靠性，从而为辐射事故或其他辐射暴露事件的剂量测量提供可靠的结果。
