摘要：
The organ doses and the effective dose of patients exposed at an X-ray beam. having photon energies between 10-150 keV. ire analyzed by using a new method named IradMed Three major radiological procedures. mammography. radiography and Computer Tomography are considered The Rayleigh scattering, the Compton scattering and the photoelectric effect were taken into account for patient dose calculations. The Compton scattering is modeled by using "classic". Kahn. Wrelopolski and EGS procedures The best results for angular distribution was obtained when the EGS-based algorithm was used. It can be noted that patient doses determined by using Kahn or "classic" procedures are in good agreement with data from literature when similar computing methods are used From our data, for patient dose calculations. the EGS procedure is recommended
