title: Absolute kilovoltage calibration of a diagnostic x-ray generator.
abstract: A method for absolute calibration of diagnostic x-ray generators is presented and discussed. The method employs a Ge(Li) detector and relies on the direct observation of the onset of fluorescence radiation from scattering foils placed in the primary beam.
