Comparison of air kerma measurements for Tungsten anode based mammographic X-ray beam quantities

Project Description

The objective of this comparison is to support the IAEA CMCs for diagnostic calibration of ionization chambers used in mammography in terms of air kerma. For this purpose an indirect comparison is proposed between the air kerma standards of the IAEA and the PTB in the mammography x-ray range from 25 kV to 35 kV, using tungsten anode X-ray tube with Mo and AL filtrations. The comparison radiation qualities WMV 25, 28, 30, 35 and WAV 25,28,30,35 (according to the PTB code) and transfer ionization chamber type Radcal RC6M were selected.


Final Report 2016-02-28

The comparison has been completed and results are published in the KCDB.
