title: Conversion coefficients for H'(3;Ω) for photons.
abstract: In this work, conversion coefficients for the operational quantity H'(3;Ω) have been calculated for both mono-energetic photons from 2 keV to 50 MeV for angles of incidence from 0° up to 180° in steps of 15° (to complement ICRU 57) as well as for photon reference radiation qualities (to complement ISO 4037). Finally, parameters necessary to determine the influence of the air density on the conversion coefficients have been determined.
