Designation:D728317Standard Test Method forAlpha and Beta Activity in Water By Liquid ScintillationCounting1This standard is issued under the fixed designation D7283;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 test method covers the measurement of grossalpha-and beta-activity concentrations in a homogeneouswater sample.It is applicable to alpha emitters with activityconcentration levels above 0.11 Bq/L(3 pCi/L)and betaemitters with activity concentration levels above 0.15 Bq/L(4pCi/L).This test method is not applicable to samples contain-ing radionuclides that are volatile under conditions of theanalysis.1.2 This test method may also be used for the directmeasurement of gross alpha-and beta-activity concentrationsin homogeneous water samples with alpha emitter activityconcentration levels above 1.8 Bq/L(50 pCi/L)and betaemitter activity concentration levels above 3.7 Bq/L(100pCi/L).1.3 This test method was tested using single-operatortests.2,3Acollaborative study following the U.S.EPA“Protocolfor the Evaluation of Alternate Test Procedures for AnalyzingRadioactive Contaminants in Drinking Water”was performed.The results of this study are on file at ASTM Headquarters.41.4 The values stated in SI units are to be regarded asstandard.The values given in parentheses are mathematicalconversions to pCi/L that are provided for information onlyand are not considered standard.An exception is noted inSection 14.1.5 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 appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:5D1129 Terminology Relating to WaterD1125 Test Methods for Electrical Conductivity and Resis-tivity of WaterD1193 Specification for Reagent WaterD1890 Test Method for Beta Particle Radioactivity of WaterD1943 Test Method for Alpha Particle Radioactivity ofWaterD3370 Practices for Sampling Water from Closed ConduitsD3648 Practices for the Measurement of RadioactivityD3856 Guide for Management Systems in LaboratoriesEngaged in Analysis of WaterD4448 Guide for Sampling Ground-Water Monitoring WellsD5847 Practice for Writing Quality Control Specificationsfor Standard Test Methods for Water AnalysisD6001 Guide for Direct-Push Groundwater Sampling forEnvironmental Site CharacterizationD7902 Terminology for Radiochemical AnalysesE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods1This test method is under the jurisdiction of ASTM Committee D19 on Waterand is the direct responsibility of Subcommittee D19.04 on Methods of Radiochemi-cal Analysis.Current edition approved June 1,2017.Published June 2017.Originallyapproved in 2006.Last previous edition approved in 2013 as D7283 13.DOI:10.1520/D7283-17.2Wong,C.T.,Soliman,V.M.,and Perera,S.K.,Journal of Radioanalytical andNuclear Chemistry,Vol 264,No.2,2005,pp.357363.3Ruberu,S.R.,Liu,Y.G.,and Perera,S.K.,Health Physics,Vol 95,No.4,October 2008,pp.397406.4Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D19-1195.ContactASTM CustomerService at serviceastm.org.5For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 E691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 Other Standards and Publications:EPA 900.0 Gross Alpha and Gross Beta Radioactivity inDrinking Water,from Prescribed Procedures for Measure-ment of Radioactivity in Drinking Water(EPA-600/4-80-032)6Standard Methods 7110C Coprecipitation Method for GrossAlpha Radioactivity in Drinking Water7Standard Methods 8010E Table 8010:Recommended Com-position for Reconstituted Fresh Water7ISO 9696 Water Qualit
