Aspects of international metrology

Oral

Since 1976, the International Bureau of Weights and Measures (BIPM) operates the International Reference System (SIR) which provides international comparisons of radioactivity standards. This system is based on a re-entrant ionization chamber and a specific approach to provide robust comparison values over decades [1]. Although the system has proven its worth for many gamma-emitting...

Science-based decision making crucially depends on the quality of the metrology from which it derives its information. Measurements with incomplete uncertainty budgets can lead to a misinterpretation about the phenomena under investigation, sometimes with fundamental implication in science and policy...

2. Herceg-Novi Summer School, the starting point in the history of the International Committee for Radionuclide Metrology

Dr Maria Sahagia (IFIN-HH, Romania)

Aspects of international metrology

Oral

This paper presents some of the most important points connected with the 1972 Herceg-Novi Radionuclide Metrology Summer School and its impact on the forthcoming evolution of the field, as follows: (i) Topics of the conference, their state of the art at that moment and recommendations for future developments, as published in the journal Nuclear Instruments and Methods 112 (1973)1-398, (NIM...
