Abstract:
Objective:To complete experiments of the energy response compensation for three semiconductor personal dosimeters in order to meet the requirements of IEC and National Standard.Methods: In Beijing SSDL, the semiconductor detectors were covered by the different thicknesses of Pb and Sn additional filters with several diameter holes to compensate the dosimeters’ energy response.Results: At the 50 keV-Cs-137 energy range, the measuring error of dosimeters is met within 30% of energy response.Conclusion:By the compensation of combined Pb and Sn filters with a hole, the semiconductor personal dosimeters can be used for radiation monitoring.
