Dosimetry and Medical Radiation Physics (DMRP)

Radiation Metrology Supporting the Network of SSDLs

In order to utilize nuclear technology for the safe and effective diagnosis and treatment of disease, Member States must be able to measure ionizing radiation including the radiation protection quantities of interest for occupationally exposed persons and for protection of the general public. Although several Member States have the capability to provide calibrations of radiation measuring equipment, those who are not members of the Meter Convention have no means, other than the Agency, to get traceability and/or verify the quality of their calibration and measurement capabilities (CMCs). The Agency operates the central dosimetry calibration laboratory at Seibersdorf to provide Member States with radiation measurement calibration services through a network of Secondary Standards Dosimetry Laboratories (the SSDL Network). To be able to function as a calibration laboratory, it is necessary for the Agency to maintain its own calibrated measurement standards, to compare these at the level of the Consultative Committee for Radiation Measurement (CCRI) and to operate a quality assurance system. The Agency is supported in these activities by international collaborations, for example, by WHO, the Bureau International des Poids et Mesures (BIPM), the International Commission on Radiation Units and Measurements (ICRU) and several Primary Standards Dosimetry Laboratories (PSDLs). The ultimate beneficiaries are patients undergoing diagnostic tests or radiation therapy, and radiation workers utilizing nuclear technology
