Radiopharmaceutical therapy using alpha-emitting radionuclides such as 223Ra and 225Ac is proving to be highly effective in fighting several forms of cancer. The safe and effective use of these types of drugs relies on the ability to make accurate measurements of the amount of the drug, measured clinically as the amount of radioactivity, being administered to the patient. Because of...

In the August 2023 edition of Measure for Measure in Nature Physics, Dr Carine Michotte took the readers on a journey through a condensed history of radionuclide metrology, starting from its remarkable inception in 1913 – when Marie Curie introduced the first international standard for Ra-226 at the BIPM – and spanning to activity measurement standards, logistical challenges of...

The CCRI was held at the Pavillon du Mail at the BIPM headquarters in Sèvres, France, and was well attended in person (36 participants) and additionally had online participation (30 attendees). This was the first in person meeting of the CCRI since the global pandemic was declared in 2020. The meeting was chaired by the new CCRI president JT Janssen from NPL. The following list...

The  CCRI Section II (Measurement of Radionuclides) met at the BIPM in Sèvres on 5-7 June 2023. There were 24 members and guests meeting in person, and an additional 19 total at various times virtually. The first half-day was held jointly with the KCWG(II). The main recommendations and actions from this meeting were: The opening of the BIPM(II)-K5 comparison, following the ...

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...
