title: Determination of the energy fluence of diagnostic x-ray beams from field measurements of attenuation curves.
abstract: The use of field measurements of attenuation curves of low-energy x-ray beams as a functional description of the beams is presented in this work. The energy fluence carried by diagnostic x-ray beams has been determined from A1 attenuation measurements made with a quality control ionization chamber for diagnostic x-ray equipment and with a low-volume ionization chamber. The obtained values are compared with those obtained from a catalog of spectral data for diagnostic x rays.
