CHAIN OF CUSTODY, sample preparation and analysis, data reduction and recording, data assessment and reporting, and final sample disposal. Procedures are also needed for addressing support functions, such as operation of process monitors, training, preparation of QUALITY CONTROL SAMPLES, collection of meteorological data, corrective actions, AUDITS, and records. Individuals satisfying the qualifications described in Section C.2 of this Regulatory Guide should write, review, and revise these procedures. Instructions, procedures, or schedules should be prepared for the functions associated with the QA program, such as the following: • ancillary laboratory functions (including cleaning of glassware, contamination control, and storage of standards and chemicals) • CALIBRATION and QC of instrumentation (including range of activity, range of energy, and frequency of calibration) • internal QC and external PE programs (including frequency, types, acceptance criteria for the laboratory PERFORMANCE TESTING samples, and individual analyst qualifications) • timetable for VERIFICATION and VALIDATION (V&V) of data Chapters 9, 11, and 12 of MARLAP provide guidance on the radioanalytical laboratory activities for which procedures are used. MARLAP Chapters 12 – 16 provide technical information that can be used to write or revise procedures. ISO/IEC 17025-2005 (Section 5.4) provides additional guidance regarding the content and quality aspects of procedure and method technical content. ANSI/ASQC E4-1994 (Section 2.5.2) identifies procedures that should be documented and may need control. 4. Records Facilities should maintain a system that produces unequivocal, accurate records that document all monitoring activities. Records of implementation or ongoing activities, such as the following, should be maintained: • procedure revision • personnel training and qualification records • analytical results • audits • corrective actions • intermediate activities or
