Abstract
This report details analyses in the development of certain correction factors for free-air ionization chambers used by the National Institute of Standards and Technology to realize air kerma for its measurement standards and calibrations of W-anode x-ray beams. The correction factors dealt with in this report are the electron-loss correction, kel, the photon-scatter correction, ksc, the fluorescence-reabsorption correction, kfl, and the bremsstrahlung-reabsorption correction, kbr.Citation
