Ionizing Radiation Department

The BIPM is advancing dosimetry services for National Metrology Institutes (NMIs) by expanding its use of off-site facilities for calibration and comparison services.

Improved metrological traceability of challenging-to-measure radionuclides

The BIPM has received the first standard solution of Technetium-99 for measurement using the newly implemented ESIR.

Advances in traceability for nuclear medicine

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.

Human- and machine-readable key comparison reports using the PDF/A-3 format

The BIPM is pleased to announce the publication of the first key comparison report embedding machine-readable versions of the document.
