1.1 This is a practice for using a radiochromic optical waveguide dosimetry system to measure absorbed dose in materials irradiated by photons and high energy electrons in terms of absorbed dose to water. The radiochromic optical waveguide dosimetry system is generally used as a routine dosimetry system. 1.2 The optical waveguide dosimeter is classified as a Type II dosimeter on the basis of the complex effect of influence quantities (see 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 ASTM 52628 for an optical waveguide dosimetry system. It is intended to be read in conjunction with ASTM Practice 52628 . 1.4 This practice applies to radiochromic optical waveguide dosimeters that can be used within part or all of the specified ranges as follows: 1.4.1 The absorbed dose range is from 1 Gy to 20 000 Gy. 1.4.2 The absorbed dose rate is from 0.001 Gy/s to 1000 Gy/s. 1.4.3 The radiation photon energy range is from 1 MeV to 10 MeV. 1.4.4 The radiation electron energy range is from 3 MeV to 25 MeV. 1.4.5 The irradiation temperature range is from –78 °C to +60 °C. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The radiochromic optical waveguide dosimetry system provides a means of measuring absorbed dose in materials. Under the influence of ionizing radiation such as photons, chemical reactions take place in the radiochromic optical waveguide creating and/or modifying optical absorbance bands in the visible region of the spectrum. Optical response is determined at selected wavelengths using the equations in 3.1.4 . Examples of appropriate wavelengths for the analysis for specific dosimetry systems are provided by their manufacturers and in Refs ( 1- 5 ). 4.2 These dosimetry systems commonly are applied in the industrial radiation processing of a variety of products, for example, the sterilization of medical devices and radiation processing of foods ( 4- 6 ).
