One of the main tasks in occupational radiation protection is the reliable determi~rnnation of radiation protection dose quantities like effective dose or organ equivalentrndose. Basic dosimetric quantities like air kerma or operational dose quantities likernambient dose equivalent, directional dose equivalent or personal dose equival~nt asrnmeasured by dosimeters provide only a rough approximation of the radiation protec~rntion quantities. To obtain a more detailed description of an exposure situation inrnterms of protective quantities the radiation field has to be analyzed with regard to itsrntype, spectral energy distribution and direction of incidence to provide the necessaryrninformation for the conversion of operational quantities into protection quantities.rnIn this work the spectroscopy of x~rays scattered by a patient. simulated by a wa~rntel' phantom, during fluoroscopic examination is investigated. The experiments arernperformed using a diagnostic x~ray unit. A spectrometer with a high~purity genna~rnnium detector is operated in a highly collimated x-ray beam. An ionization chamberrnin the entrance field of the phantom serves as a monitor and provides reference valuesrnof the x-ray tube output.rnScattered x-ray spectra are recorded for different tube voltages. spectrometerphantomrndistances and angular positions with respect to the direction of the inci~rndent x-rays. To validate the spectroscopic method, spectra of direct x-rays are alsornmeasured and compared with reference spectra
