主　　题：personal dose equivalent photon dosimetry diode detector energy compensation 

摘      要：During the last few years,active personal dosimeters have been developed and have replaced passive personal dosimeters in some external monitoring systems,frequently using silicon diode *** photons interact with the constituents of the diode detector and produce *** photon-induced electrons deposit energy in the detector＇s sensitive region and contribute to the response of diode *** achieve an appropriate photon dosimetry response,the detectors are usually covered by a metallic layer with an optimum *** metallic cover acts as an energy compensating *** this paper,a software process is performed for energy *** data sampling based on pulse height is used to determine the photon dose *** method is applied to improve the energy response in photon *** detector design is optimized for the response function and determination of the photon dose *** personal dose equivalent is determined in the energy range of 0.3-6 *** error values of the calculated data for this wide energy range and measured data for ^133Ba,^137Cs,^60Co and ^241Am-Be sources respectively are up to 20%and 15%.Fairly good agreement is seen between simulation and dose values obtained from our process and specifications from several photon sources.
