Quality control methodology and implementation of X-radiation standards beams, mammography level, following the standard IEC 61267

This study presents the results of the establishment of a quality control program developed and applied for the X-ray system of the Calibration Laboratory of IPEN. The X-ray standard beams, mammography level, using molybdenum and aluminum as additional filtration were established after the application of this quality control and the spectrometry of these qualities was made. The reference ionization chamber has traceability to the PTB. The radiation qualities RQR-M, RQA-M, RQN-M and RQB-M, following the recommendations of the IEC 61267 and the IAEA TRS 457 were established.

► Determination of the additional filtration for each mammography radiation quality.
► Determination of the KQ values for the WAV and WMV radiation qualities.
► Determination of the air-kerma rates for all radiation qualities.
► The uncertainties have been calculated using the type A and type B uncertainties.
► Establishment of the qualities that use a PMMA phantom (WAN, WAB, WMN and WMB).
