Dosimetry for diagnostic radiology

Working Group 6.25

Profile

The fundamental quantity in the dosimetry of ionizing radiation is the absorbed dose to matter in units of J/kg with the special name “gray” (Gy). The working group 6.25 is responsible for the realization and dissemination of the gray for x- and gamma radiation. Thereby the group creates the metrological basis for the dosimetry in radiation protection as well as in medical x-ray diagnostics and therapy. Key tasks are calibration, testing, certification and consulting. The focus in research and development is the improvement of the primary standards and the dosimetry for medical x-ray diagnostics including mammography and computed tomography.
