1、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
2、 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 s
3、terile 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 gam
4、ma,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
