Practice for use of the alanine-EPR dosimetry system
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 well-defined 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.
