Designation:D560810Standard Practices forDecontamination of Field Equipment Used at Low LevelRadioactive Waste Sites1This standard is issued under the fixed designation D5608;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.Scope*1.1 These practices cover the decontamination of fieldequipment used in the sampling of soils,soil gas,sludges,surface water and groundwater at waste sites known orsuspected of containing low level radioactive wastes.1.2 This practice is applicable at sites where low levelradioactive wastes are known or suspected to exist.Thispractice may also be applicable for the decontamination ofequipment used in known or suspected transuranic,or mixedwastes when used by itself or in conjunction with PracticeD5088.1.3 Procedures are contained in this practice for the decon-tamination of equipment that comes into contact with thesample matrix(sample contacting equipment),and for ancil-lary equipment that has not contacted the sample,but may havebecome contaminated during use(non-contacting equipment).For sample contacting equipment there are four separateprocedures(Procedure A through D)in Section 8.For non-contacting equipment,one procedure is presented as covered inSection 9.1.4 This practice is applicable to most conventional sam-pling equipment constructed of metallic and hard,smoothsynthetic materials.Materials with rough or porous surfaces,orhaving a high sorption rate should not be used in radioactivewaste sampling due to the difficulties with decontamination.1.5 In those cases where sampling will be periodicallyperformed,such as sampling of wells,consideration should begiven to the use of dedicated sampling equipment if legitimateconcerns exist for the production of undesirable or unmanage-able waste byproducts,or both,during the decontamination oftools and equipment.1.6 This practice does not address regulatory requirementsfor personnel protection or decontamination,or for the han-dling,labeling,shipping,or storing of wastes or samples.Specific radiological release requirements and limits must bedetermined by users in accordance with local,state and federalregulations.1.7 For additional information in the United States,see U.S.Department of Energy(DOE)10 CFR Part 835 and U.S.Nuclear Regulatory Commission(NRC)10 CFR Part 20.1.8 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.9 This practice offers an organized collection of informa-tion or a series of options and does not recommend a specificcourse of action.This document cannot replace education orexperience and should be used in conjunction with professionaljudgement.Not all aspects of this practice may be applicable inall circumstances.This ASTM standard is not intended torepresent or replace the standard of care by which theadequacy of a given professional service must be judged norshould this document be applied without consideration of aprojects many unique aspects.The word“standard”in thetitle of this document means only that the document has beenapproved through the ASTM consensus process.1.10 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.Specific precau-tionary statements are given in Section 6.2.Referenced Documents2.1 ASTM Standards:2D653 Terminology Relating to Soil,Rock,and ContainedFluidsD5088 Practice for Decontamination of Field EquipmentUsed at Waste Sites1This practice is under the jurisdiction of ASTM Committee D18 on Soil andRock and is the direct responsibility of Subcommittee D18.21 on Groundwater andVadose Zone Investigations.Current edition approved May 1,2010.Published June 2010.Originallyapproved in 2001.Last previous edition approved in 2006 as D560801(2006).DOI:10.1520/D5608-10.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 2.2 United States Code of Federal Regulations:310 CFR Part 20 Standards for Protection Against Radiation10 CFR Part 835 Radiological Protection for OccupationalWorkers3.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 as low as reasonable achievable(ALARA)an ap-proach to radiological control to manage exposures to the workforce and to the general public at levels as low as is
