Abstract:
The PIANOLIB activity aims to harmonize the calibrations of the measurement equipment in the region and to evaluate the quality of this kind of measurement by means of a proficiency test exercise. In this report the results of the proficiency test are presented. The exercise consisted in determining the activity of a phantom filled with two sets of certified radioactive materials, K-40 and Cs-137, in radioactive rods, uniformly spaced inside of the phantom. Most of the participants were able to quantify correctly the activities of K-40 and Cs-137 and by comparison with the results of a previous exercise of this kind, the overall performance is equally good. The problems experienced by laboratories which submitted non-acceptable results could generally be attributed to the calibration of their systems. It is important to keep the practice of intercomparison and NKS continues to be the best framework for supporting this kind of activity.
