Description / Abstract:
This is a practice for using polymethylmethacrylate (PMMA)
dosimetry systems to measure absorbed dose in materials irradiated
by photons or electrons in terms of absorbed dose to water. The
PMMA dosimetry system is classified as a routine dosimetry
system.
The PMMA dosimeter is classified as a Type II dosimeter on the
basis of the complex effect of influence quantities (see ASTM
Practice E2628).
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 a PMMAdosimetry system. It is intended to be read
in conjunction with ASTM E2628.
This practice covers the use of PMMA dosimetry systems under the
following conditions:
the absorbed dose range is 0.1 kGy to 150 kGy.
the absorbed dose rate is 1 3 10−2 to 1 3
107 Gy·s−1.
the photon energy range is 0.1 to 25 MeV.
the electron energy range is 3 to 25 MeV.
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.
