Reference dosimetry at the Australian Synchrotron's imaging and medical beamline using free‐air ionization chamber measurements and theoretical predictions of air kerma rate and half value layer

Abstract

The authors showed in this study their ability to verify the predicted air kerma rate and x-ray attenuation curve on the IMBL using a simple experimental method, namely, HVL measurements. The HVL measurements strongly supports the x-ray beam spectrum, which in turn has a profound effect on x-ray dosimetry.
