At first sight, the theme for World Metrology Day 2024 – Sustainability – does not seem to have much overlap with the activities of primary and secondary standard dosimetry laboratories. However, when one considers the meaning of sustainability in the light of the 17 UN Sustainability Goals it becomes more obvious that ionizing radiation is very relevant to the subject and, by...

Dr Anna Villevalde joined the Ionizing Radiation Department as a dosimetry physicist in April 2024. Before joining the BIPM, Dr Villevalde worked at the D.I. Mendeleyev Institute for Metrology (VNIIM) since 2006 as a researcher responsible for primary standards in ionizing radiation dosimetry, focusing on low- and medium-energy x-rays, gamma rays and brachytherapy. She actively...

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...
