This practice covers the preparation, testing, and procedure for using the acidic aqueous silver dichromate dosimetry system to measure absorbed dose in water when exposed to ionizing radiation. The system consists of a dosimeter and appropriate analytical instrumentation. For simplicity, the sys-tem will be referred to as the dichromate system. It is classified as a reference standard dosimetry system (see ISO/ASTM Guide 51261). This practice describes the spectrophotometric analysis procedures for the dichromate system. This practice applies only to g-rays, X-rays/bremsstrahlung, and high energy electrons. This practice applies provided the following conditions are satisfied: The absorbed dose range is from 2 3 10 3 to 5 3 10 4 Gy.
