Scope

.1 This is a practice for using a cellulose triacetate (CTA)dosimetry system to measure absorbed dose in materialsirradiated by photons or electrons in terms of absorbed dose towater. The CTA dosimetry system is classified as a routinedosimetry system.1.2 The CTA dosimeter is classified as a type II dosimeteron the basis of the complex effect of influence quantities on itsresponse (see ASTM Practice E2628).1.3 This document is one of a set of standards that providesrecommendations for properly implementing dosimetry inradiation processing, and describes a means of achievingcompliance with the requirements of ASTM E2628 “Practicefor Dosimetry in Radiation Processing” for a CTA dosimetrysystem. It is intended to be read in conjunction with ASTME2628.1.4 This practice covers the use of CTA dosimetry systemsunder the following conditions:1.4.1 The absorbed dose range is 10 kGy to 300 kGy.1.4.2 The absorbed-dose rate range is 3 Gy/s to 4×1010 Gy/s(1).21.4.3 The photon energy range is 0.1 to 50 MeV.1.4.4 The electron energy range is 0.2 to 50 MeV.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appropriatesafety and health practices and determine the applicabilityof regulatory limitations prior to use.
