Designation:E 2701 09An American National StandardStandard Guide forPerformance Characterization of Dosimeters and DosimetrySystems for Use in Radiation Processing1This standard is issued under the fixed designation E 2701;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide provides guidance on determining the per-formance characteristics of dosimeters and dosimetry systemsused in radiation processing.1.2 This guide describes the influence quantities that mightaffect the performance of dosimeters and dosimetry systemsand that should be considered during dosimeter/dosimetrysystem characterization.1.3 Users of this guide are directed to existing standards andliterature for procedures to determine the effects from indi-vidual influence quantities and from combinations of more thanone influence quantity.1.4 Guidance is provided regarding the roles of the manu-facturers,suppliers,and users in the characterization of dosim-eters and dosimetry systems.1.5 This guide does not address how the dosimeter/dosimetry system characterization information is to be used inradiation processing applications or in the calibration ofdosimetry systems.NOTE1For guidance on the use of dosimeter/dosimetry systemcharacterization information for the selection and use of a dosimetrysystem,the user is directed to Practice E 2628.NOTE2For guidance on the use of dosimeter/dosimetry systemcharacterization information for dosimetry system calibration,the user isdirected to ISO/ASTM Guide 51261.1.6 This guide does not purport to address all of the safetyconcerns,if any,associated with its use.It is the responsibilityof the user of this standard to establish appropriate safety andhealth practices and determine the applicability of regulatorylimitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E 170 Terminology Relating to Radiation Measurementsand DosimetryE 456 Terminology Relating to Quality and StatisticsE 1026 Practice for Using the Fricke Reference-StandardDosimetry SystemE 1325 Terminology Relating to Design of ExperimentsE 2628 Practice for Dosimetry in Radiation Processing2.2ISO/ASTM Standards:251205 Practice for Use of a Ceric-Cerous Sulfate DosimetrySystem51261 Guide for the Selection and Calibration of DosimetrySystems for Radiation Processing51707 Guide for Estimating Uncertainties in Dosimetry forRadiation Processing2.3ISO Reports:3GUM Guide to the Expression of Uncertainty in Measure-ments,1995.VIM International Vocabulary of Basic and General Termsin Metrology2.4International Commission on Radiation Units andMeasurements(ICRU)Reports4Report 60 Fundamental Quantities and Units for IonizingRadiationReport 80 Dosimetry Systems for Use in Radiation Process-ing3.Terminology3.1 Definitions:3.1.1 calibration curveexpression of the relation betweenindication and corresponding measured quantity value.VIM:20083.1.2 dosimeterdevice that,when irradiated,exhibits aquantifiable change that can be related to absorbed dose in agiven material using appropriate measurement instruments andprocedures.3.1.3 dosimter batchquantity of dosimeters made from aspecific mass of material with uniform composition,fabricatedin a single production run under controlled,consistent condi-tions and having a unique identification code.3.1.4 dosimter/dosimetry system characteristizationdetermination of performance characteristics,such as useful1This guide is under the jurisdiction of ASTM Committee E10 on NuclearTechnology and Applications and is the direct responsibility of SubcommitteeE10.01 on Radiation Processing:Dosimetry and Applications.Current edition approved July 15,2009 Published September 2009.2For referenced ASTM and ISO/ASTM standards,visit the ASTM website,www.astm.org,or contact ASTM Customer Service at serviceastm.org.ForAnnual Book of ASTM Standards volume information,refer to the standardsDocument Summary page on the ASTM website.3Available from the International Commission on Radiation Units and Mea-surements,7910 Woodmont Ave.,Suite 800,Bethesda,MD 20814,USA.4Available from the International Organization for Standardization,1 rue deVarembe,Case Postale 56,CH-1211,Geneva 20,Switzerland.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.dose range,reproducibilty and the effects of influence quanti-ties,for a dosimeter/dosimetry system under defined testconditions.3.1.5 dosimeter responsereproducible,quantifiable effectproduced in the dosimeter by ionizing radiation.3.1.5.1 DiscussionThe dosimeter response value,ob-tained from one or more measurements,is used in the estima-tion of the derived absorbed dose.The response value may beobtained from such measurements as optical absorbance,thickness,mass,peak-to-peak distan
