6. Part II – Station monitoring and troubleshooting process
AS5.4/SM5.05
Introduction
Part 1
Part 2
Part 3
Conclusions
As part of the station quality program, on a routine basis some radionuclide samples are re-measured by laboratories. In case of large discrepancies corrective actions are implemented.

7. Part III – Laboratory Proficiency Test Exercises
PRELIMINARY REPORT TO LABS
A preliminary report on results of evaluation is sent to each respective lab for review and comments. After period of review, the final results are sent to laboratories for comments
EVALUATION OF RESULTS
A lab's ability of correct nuclide identification, correct quantification of activity and activity concentration are assessed, using performance statistics from ISO13528:2005
SUBMISSION BY LABORATORIES OF ANALYTICAL RESULTS
Laboratories their analytical results by the specified.
PREPARATION OF TEST SAMPLE OR SPECTRUM
PTS sends each laboratory a sample for analysis; the nuclides present and their respective activities and activity concentrations known to PTS only
EXERCISE PLANNING
PTS defines the specific objective of the Exercise and decides on sample type, nuclides of interest, and type of exercise
CERTIFICATION / SURVEYLANCE ASSESSMENT
Corrective actions are reviewed during surveillance assessment for certified labs and certification process of uncertified labs.
RECORD OF QUALITY OF ANALYTICAL RESULTS
A summary of a lab's performance together with its results and performance indicators as well as corrective actions taken for discrepant and non-conformities are documented.
TECHNICAL REPORT
A Technical Report is prepared and sent to labs for comments. After period of review, the revised technical report is printed for distribution.
CORRECTIVE ACTION REPORT
Laboratories are required to submit a corrective action report for discrepant results which is then verified during surveillance visit (for certified labs) or certification visit (for uncertified labs). 7
