ISO/ASTM 51607:2013 covers dosimeter materials, instrumentation, and procedures for using the alanine-EPR dosimetry system for measuring the absorbed dose in the photon and electron radiation processing of materials. The system is based on electron paramagnetic resonance (EPR) spectroscopy of free radicals derived from the amino acid alanine.
The alanine dosimeter is classified as a type I dosimeter as it is affected by individual influence quantities in a welldefined way that can be expressed in terms of independent correction factors. The alanine dosimeter may be used in either a reference standard dosimetry system or in a routine dosimetry system.
ISO/ASTM 51607:2013 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 ASTM E2628 for alanine dosimetry system. It is intended to be read in conjunction with ASTM E2628.
