GSO ISO/ASTM 51956:2017 Scope
1.1 This practice covers procedures for the use of thermoluminescence
dosimeters (TLDs) to measure the absorbed dose
in materials irradiated by photons or electrons in terms of
absorbed dose to water. Thermoluminescence-dosimetry systems
(TLD systems) are generally used as routine dosimetry
systems.
1.2 The thermoluminescence dosimeter (TLD) is classified
as a type II dosimeter on the basis of the complex effect of
influence quantities on the dosimeter response. See ISO/ASTM
Practice 52628.
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 ISO/ASTM 52628 “Practice
for Dosimetry in Radiation Processing” for a TLD system.
It is intended to be read in conjunction with ISO/ASTM 52628.
1.4 This practice covers the use of TLD systems under the
following conditions:
1.4.1 The absorbed-dose range is from 1 Gy to 10 kGy.
1.4.2 The absorbed-dose rate is between 1 × 10-2 and 1 ×
1010 Gy s-1.
1.4.3 The radiation-energy range for photons and electrons
is from 0.1 to 50 MeV.
1.5 This practice does not cover measurements of absorbed
dose in materials subjected to neutron irradiation.
1.6 This practice does not cover procedures for the use of
TLDs for determining absorbed dose in radiation-hardness
testing of electronic devices. Procedures for the use of TLDs
for radiation-hardness testing are given in ASTM Practice
E668.
1.7 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 appro
appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use.
