ISO/ASTM 51026:2015规程涵盖了制备、测试和使用酸性含水硫酸亚铁铵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程序。该系统由剂量计和适当的分析仪器组成。该系统将被称为弗里克剂量测定系统。Fricke剂量测定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 51026:2015 practice covers the procedures for preparation, testing and using the acidic aqueous ferrous ammonium sulfate solution dosimetry system to measure absorbed dose to water when exposed to ionizing radiation. The system consists of a dosimeter and appropriate analytical instrumentation. The system will be referred to as the Fricke dosimetry system. The Fricke dosimetry system may be used as either a reference standard dosimetry system or a routine dosimetry system.
