Characterization of the new free-air primary standard for low-energy X-rays at CMI

Popis výsledku v původním jazyce

In 2011 a decision was made by Czech Metrology Institute to build a free-air ionization chamber (FAC) intended to be used as a primary standard of air kerma rate for low-energy X-rays (photon energy below 50 keV, including mammography X-ray qualities) inorder to replace the currently used secondary ionization chamber and to decrease the uncertainty of air kerma reference value. In the period 2011?2012, the FAC has been designed, manufactured and put into operation. Its performance was tested using a calibrated secondary chamber and then by an informal comparison with a national primary standard of BEV (Austria). Physical characteristics of the FAC are described and individual correction factors are discussed focusing on computational methods utilizedin their estimation. Summary of the correction factors with the uncertainty budget is presented.
