title: Calibration of a NaI spectrometer in dose equivalent quantities.
abstract: A sodium iodide spectrometer was calibrated in terms of dose equivalent quantities. The detector was irradiated with a known dose (dose equivalent) at 12 ISO x-ray qualities between 33 keV and 248 keV. The method of calibration is based on the relationship between the considered dose equivalent delivered by each x-ray quality and the linear combination of the number of counts in a set of six fixed energy ranges. This procedure allows for the evaluation of the effective dose equivalent, the whole-body dose equivalent and the testes dose equivalent for parallel irradiation with a maximum and minimum relative deviation from the reference values of +11% and -21%, respectively.
