The end of March 2023 marks the end of my term as a Member of CIPM and President of CCRI, as well as my retirement from NPL (the UK’s NMI). It has been a privilege to be President of CCRI and to work with such an active and committed community of metrologists from across the globe; committed to metrology and committed to ensuring its benefits are realized in the enormous number of applications...

Validation work is continuing for the International Reference System for α- and pure β-emitting radionuclides (ESIR) in anticipation of a significant expansion of the therapeutic use of radiopharmaceuticals. The CCRI 2018-2028 Strategy and underlying stakeholder consultation predicted a significant expansion of the therapeutic use of radiopharmaceuticals. This motivated an extensive analysis...

This online workshop is open to experts and stakeholders from both radionuclide metrology and inorganic chemical analysis communities with experience or interest in using mass spectrometry to support metrological analysis of radioactive elements in applications such as nuclear power, environmental stewardship, forensics and medicine, and the nuclear data supporting the counting methods used in...

The workshop was aimed at people from RMOs who have developed, are developing or wish to develop digital electronics suitable for a RMO SIRTI comparison based on a NaI(Tl) well counter. The objective of this workshop with 35 participants from 16 NMIs/DIs was to : define the needs by discussing techniques for accurate live-time corrections share experience with different digital electronics...

The BIPM is looking for a scientist with experience in radionuclide metrology for the development of a new, high precision method to compare primary standards of alpha-emitting radionuclides. Please contact the Department Director, Dr Vincent Gressier, to discuss the project and confirm whether the secondment opportunity is still available. Further information available here.

Radioactive sources are at the heart of CCRI activities, whether it is a reference field for the calibration of instruments, an unknown sample that needs to be identified and standardized, or a check source that monitors system stability. However there are pressures from several different directions to reduce the use of radioactive sources in ionizing radiation applications, replacing them with...

The KCWG(II) has posted the Measurement Methods Matrix (MMM), as a tool for evaluating CMCs in radioactivity, on the BIPM website. In the interest of supporting the calibration and measurement capabilities (CMCs) published by National Measurement and Designated Institutes (NMIs and DIs) on the Key Comparison Database (KCDB), the Consultative Committee on Ionizing Radiation Section II...

The Henri Becquerel National Laboratory (LNHB) at @CEA-List is participating in the World Metrology Day! Two videos are available in English. Other videos are available in French on the LNHB website (http://www.lnhb.fr/categorie/actualite/#journee-mondiale-de-la-metrologie-2022).   The LNHB is the French national laboratory for metrology in the field of ionizing radiation. As such, it belongs...

The value of the range of communication channels the CCRI can use to engage, inform and support the Ionizing Radiation (IR) community has been demonstrated in the last years; in particular electronic communication (Webinars, e-learning, Blog, Newsletter, YouTube). Although this is led, coordinated and mostly resourced from the BIPM work programme, it would be valuable to ensure that the...

The Low-Level Radioactivity Measurement Techniques (LLRMT) 2022 conference will take place at Gran Sasso National Laboratory (LNGS), Italy, on 2-6 May 2022.
