ISO/ASTM 51631:2013,Practice for use of calorimetric dosimetry systems for electron beam dose measurements and dosimetery system calibrations.
ISO/ASTM 51631:2013 covers the preparation and use of semiadiabatic calorimetric dosimetry systems for measurement of absorbed dose and for calibration of routine dosimetry systems when irradiated with electrons for radiation processing applications.
This document 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 ASTM Practice E2628 for a calorimetric dosimetry system. It is intended to be read in conjunction with ASTM Practice E2628.
The calorimeters described in this practice are classifiedas Type II dosimeters on the basis of the complex effect of influence quantities. See ASTM Practice E2628.
This practice applies to electron beams in the energy range from 1.5 to 12 Mev.
The absorbed dose range depends on the absorbing material and the irradiation and measurement conditions.Minimum dose is approximately 100 Gy and maximum dose is approximately 50 kGy.
