ISO/ASTM 51401:2013涵盖了使用酸性重铬酸银水溶液剂量测定系统测量暴露于电离辐射时对水的吸收剂量的制备、测试和程序。该系统由剂量计和适当的分析仪器组成。为简单起见，该系统将被称为重铬酸盐系统。根据影响量的影响，重铬酸盐剂量计被归类为I型剂量计。重铬酸盐系统可用作参考标准剂量测定系统或常规剂量测定系统。 ISO/ASTM 51401:2013是一套标准之一，该标准提供了在辐射处理中正确实施剂量测定的建议，并描述了实现符合ISO/ASTM规程52628中重铬酸盐剂量测定系统要求的方法。本标准将与ISO/ASTM 52628规程一起阅读。 ISO/ASTM 51401:2013描述了重铬酸盐体系的分光光度分析程序。它只适用于伽马辐射、X辐射/韧致辐射和高能电子。

ISO/ASTM 51401:2013 covers the preparation, testing, and procedure for using the acidic aqueous silver dichromate dosimetry system to measure absorbed dose to water when exposed to ionizing radiation. The system consists of a dosimeter and appropriate analytical instrumentation. For simplicity, the system will be referred to as the dichromate system. The dichromate dosimeter is classified as a type I dosimeter on the basis of the effect of influence quantities. The dichromate system can be used as either a reference standard dosimetry system or a routine dosimetry system. ISO/ASTM 51401:2013 is one of a set of standards that provides recommendations for properly implementing dosimetry in radiation processing, and describes a means of achieving compliance with the requirements of ISO/ASTM Practice 52628 for the dichromate dosimetry system. It is intended to be read in conjunction with ISO/ASTM Practice 52628. ISO/ASTM 51401:2013 describes the spectrophotometric analysis procedures for the dichromate system. It applies only to gamma radiation, X-radiation/bremsstrahlung, and high energy electrons.
