Supply of an x-ray emitting equipment for the calibration of radiation detector equipment in mammography energy qualities and their accessories, for the National Dosimetry Center.

The Laboratory of Metrology of Ionizing Radiation of the National Dosimetry Center considers it necessary to replace the single Mo anode tube with a multitube system with three possible anodes (W, Mo, Rh) and the acquisition of the relevant filters in order to perform calibrations on radiation beams used in current mammography facilities. With these combinations we could characterize our laboratory for the energy qualities of Mo/Mo and extend it to those offered by the primary laboratory of Germany (PTB), MRV (Mo / 25 μm Rh), MAV (Mo / 1 mm Al), WAV (W / 0.5 mm Al), WRV (W / 50 μm Rh), WSV (W / 50 μm Ag), RRV (Rh / 25 μm Rh) and RAV (Rh / 1 mm Al).
