The biennial international conference on radionuclide metrology (ICRM) was held on 27-31 May 2019 in Salamanca (Spain). The conference covered developments in primary standards and novel technologies for measuring radioactivity (for example, the use of unmanned airborne spectrometers for environmental measurements).
Staff from the BIPM contributed presentations on the international reference system for pure beta emitting radionuclides (the ESIR) and the first measurement of 11C in the transportable instrument for short-lived gamma emitters (SIRTI).
The Chair of CCRI Section II gave a presentation on the long-term strategy for radionuclide metrology. The proceedings will be published in a special issue of Applied Radiation and Isotopes.
