摘要：

Interventional radiology has been beneficial for patients for over 30 years of age with the combination of diagnostic and therapeutic methods. The radiation affecting occupationally exposed workers should be evaluated by means of the energy spectra and flux of X-rays in the treatment room. The present study aims to obtain the energy spectra of interventional procedures and study the capability of some detectors to evaluate the dose in interventional procedures. These measurements were taken by silicon-drift, Cd Te, and Cd Zn Te detectors. The energy spectra were corrected by the energy-response curve of each detector. The energy-response curves of silicon-drift and Cd Te detectors provided by the manufacturers specification were used. The energy response of the Cd Zn Te detector was measured by133Ba and152Eu c sources. The experimental data were compared with the simulation results, and their perfect agreement provides a way to correct the energy or dose response, which can be used for the personal dosimeter developed by our group.Moreover, the measured energy spectra can be used in individual radiation protection. The present study shows that the Cd Zn Te detector is a good candidate detector in interventional procedures.
