IAEA Dosimetry Laboratory

The IAEA's Dosimetry laboratory (DOL) works as a central laboratory in the SSDL Network. DOL provides calibration, reference irradiation, comparison and audit services for the Member States. The laboratory was established in 1961 with the aim of preparing a dosimetry system suitable for postal dose comparisons amongst radiotherapy hospitals. The calibration service for radiation therapy were established first. Later the services were extended to cover radiation protection, brachytherapy and diagnostic radiology. The IAEA signed the CIPM MRA in 1999 and its CMCs are published in the key comparison database (KCDB). The IAEA has a comprehensive quality management system (QMS) in place for its own CMCs and it is peer-reviewed periodically by external experts. This provides confidence to the SSDL Network for the traceability of the calibrations performed by the IAEA.
