Practice for use of a thermoluminescence-dosimetry system (TLD system) for radiation processing
|Publication Date:||15 November 2013|
|ICS Code (Radiation measurements):||17.240|
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-d
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.
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.
This practice covers the use of TLD systems under the following conditions:
The absorbed-dose range is from 1 Gy to 10 kGy.
The absorbed-dose rate is between 1 × 10-2 and 1 × 1010 Gy s-1.
The radiation-energy range for photons and electrons is from 0.1 to 50 MeV.
This practice does not cover measurements of absorbed dose in materials subjected to neutron irradiation
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.
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.
