Omfattning
1.1 This practice 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.2
1.2 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 (see ASTM Practice E2628). The alanine
dosimeter may be used in either a reference standard dosimetry
system or in a routine dosimetry system.
1.3 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 E2628 “Practice
for Dosimetry in Radiation Processing” for alanine dosimetry
system. It should be read in conjunction with ASTM E2628.
1.4 This practice covers alanine-EPR dosimetry systems for
dose measurements under the following conditions:
1.4.1 The absorbed dose range is between 1 and 1.5 3
105Gy.
1.4.2 The absorbed dose rate is up to 102Gy s-1 for continuous
radiation fields and up to 3 3 1010Gy s-1 for pulsed
radiation fields (1-4).3
1.4.3 The radiation energy for photons and electrons is
between 0.1 and 30 MeV (1, 2, 5-8).
1.4.4 The irradiation temperature is between –78 °C and +
70 °C (2, 9-12).
1.5 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
