ISO/ASTM 51940:2013(E)An American National StandardStandard Guide forDosimetry for Sterile Insect Release Programs1This standard is issued under the fixed designation ISO/ASTM 51940;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.1.Scope1.1 This guide outlines dosimetric procedures to be fol-lowed for the radiation-induced reproductive sterilization oflive insects for use in pest management programs.The primaryuse of such insects is in the Sterile Insect Technique,wherelarge numbers of reproductively sterile insects are released intothe field to mate with and thus control pest populations of thesame species.A secondary use of sterile insects is as benignhosts for rearing insect parasitoids.The procedures outlined inthis guide will help ensure that insects processed with ionizingradiation from gamma,electron,or X-ray sources receiveabsorbed doses within a predetermined range.Information oneffective dose ranges for specific applications of insect steril-ization,or on methodology for determining effective doseranges,is not within the scope of this guide.NOTE1Dosimetry is only one component of a total quality assuranceprogram to ensure that irradiated insects are adequately sterilized and fullycompetitive or otherwise suitable for their intended purpose.1.2 This guide provides information on dosimetry for theirradiation of insects for these types of irradiators:self-contained dry-storage137Cs or60Co irradiators,self-containedlow-energy X-ray irradiators(maximum processing energiesfrom 150 to 300 keV),large-scale gamma irradiators,andelectron accelerators(electron and X-ray modes).NOTE2Additional,detailed information on dosimetric procedures tobe followed in installation qualification,operational qualification,perfor-mance qualification,and routine product processing can be found inISO/ASTM Practices 51608(X-ray bremsstrahlung facilities processingat energies over 300 keV),51649(electron beam facilities),51702(large-scale gamma facilities),and 52116(self-contained dry-storagegamma facilities),and in Ref(1)2(self-contained X-ray facilities).1.3 The absorbed dose for insect sterilization is typicallywithin the range of 20 to 600 Gy.1.4 This guide refers,throughout the text,specifically toreproductive sterilization of insects.It is equally applicable toradiation sterilization of invertebrates from other taxa(forexample,Acarina,Gastropoda)and to irradiation of live insectsor other invertebrates for other purposes(for example,induc-ing mutations),provided the absorbed dose is within the rangespecified in 1.3.1.5 This guide also covers the use of radiation-sensitiveindicators for the visual and qualitative indication that theinsects have been irradiated.1.6 This document is one of a set of standards that providesrecommendations for properly implementing and utilizingdosimetry in radiation processing and describes a means ofachieving compliance with the requirements ofASTM PracticeE2628.It is intended to be read in conjunction with ASTME2628.1.7 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 appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced documents2.1 ASTM Standards:3E170 Terminology Relating to Radiation Measurements andDosimetryE2303 Guide for Absorbed-Dose Mapping in RadiationProcessing FacilitiesE2628 Practice for Dosimetry in Radiation ProcessingE2701 Guide for Performance Characterization of Dosim-eters and Dosimetry Systems for Use in Radiation Process-ing2.2ISO/ASTM Standards:351261 Practice for Calibration of Routine Dosimetry Sys-tems for Radiation Processing51275 Practice for Use of a Radiochromic Film DosimetrySystem51310 Practice for Use of a Radiochromic Optical Wave-guide Dosimetry System51539 Guide for the Use of Radiation-Sensitive Indicators51607 Practice for Use of an Alanine-EPR Dosimetry Sys-tem51608 Practice for Dosimetry in an X-Ray(Bremsstrahl-ung)Facility for Radiation Processing51649 Practice for Dosimetry in an Electron Beam Facilityfor Radiation Processing at Energies Between 300 keVand 25 MeV1This guide is under the jurisdiction of ASTM Committee E61 on RadiationProcessing and is the direct responsibility of Subcommittee E61.04 on SpecialtyApplication,and is also under the jurisdiction of ISO/TC 85/WG 3.Current edition approved Dec.26,2012.Published April 2013.Originallypublished as ASTM E 194098.Last previous ASTM edition E 194098.Thepresent International Standard ISO/ASTM 51940:2013(E)replaces ASTM E194098 and is a major revision of the last previous edition ISO/ASTM51940:2004(E).2The boldface numbers in parentheses refer to the bibliography at the end of thisstandard.3For referenced ASTM and ISO/ASTM standards,visit the ASTM website,www.astm.org,or contact ASTM Customer Service at serviceastm.org.ForAnnu
