Designation:D560816Standard Practices forDecontamination of Sampling and Non Sample ContactingEquipment Used at Low Level Radioactive 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 samplingand non-sample contacting equipment used in the sampling ofsoils,soil gas,sludges,surface water and groundwater at wastesites known or suspected of containing low level radioactivewastes.It may also have application for decontamination ofsampling and heavy construction equipment used during reme-diation activities.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 The user is reminded of the importance of properdecontamination planning to minimize the amount of decon-tamination wastes generated and to reduce or eliminate the useof cleaning agents that are themselves hazardous materials.Quality Assurance/Quality Control(QA/QC)radiological sur-veys and samples that document decontamination effectivenesscan be used to modify or enhance decontamination techniques.1.5 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.1.6 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.1.7 This practice does not address regulatory requirementsfor personnel protection or decontamination,or for thehandling,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.1.8 Other jurisdictions may have equivalent requirements.For additional information in the United States,for example,see United States Department of Energy(DOE)10 CFR Part835 and U.S.Nuclear Regulatory Commission(NRC)10 CFRPart 20.1.9 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.10 This practice offers an organized collection of infor-mation or a series of options and does not recommend aspecific course of action.This document cannot replace edu-cation or experience and should be used in conjunction withprofessional judgement.Not all aspects of this practice may beapplicable in all circumstances.This ASTM standard is notintended to represent or replace the standard of care by whichthe adequacy of a given professional service must be judgednor should this document be applied without consideration ofa projects many unique aspects.The word“standard”in thetitle of this document means only that the document has beenapproved through the ASTM consensus process.1.11 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is the1This 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 Feb.1,2016.Published February 2016.Originallyapproved in 2001.Last previous edition approved in 2010 as D560810.DOI:10.1520/D5608-16.*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 responsibility 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 ContainedFluidsD1193 Specification for Reagent WaterD50
