The CCRI(I) was held from 1 to 2 June 2023 at the Vienna International Centre in conjunction with the IAEA SSDL (Secondary Standard Dosimetry Laboratories) Network meeting the 29 and 30 of May 2023. A Joint IAEA-SSDL CCRI(I) one day workshop was organized between the two meetings to enhance the links between the two communities. All these events provided online participation. 40...

  Section III (neutron metrology) of the CCRI held its 27th meeting from 9th to 12th May 2023 at the BIPM in Sevres. 33 participants, 14 of them online, discussed during 3 full days the ongoing activities and future needs of neutron metrology. One focus of the meeting was the discussion about ongoing and planned comparisons and the related long-term strategy within the ...

The Resolution 2 of the 27th CGPM on the Global digital Transformation and the International System of units encouraged the CIPM to continue its outreach and engagement initiatives to ensure that the Metre Convention naturally extends its role as the globally accepted anchor of trust for metrology into the digital era and to undertake the development and promotion of an SI Digital...

Dr Lisa Karam, the Chair of CCRI Section II: Measurement of radionuclides, was presented with the 2023 Randall S. Caswell Award by the US Council on Ionizing Radiation Measurements and Standards (CIRMS). The award is in recognition of Dr Karam’s distinguished achievements in the field of Ionizing Radiation Measurements and Standards since beginning her career as a...

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 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.

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...
