Abstract Objective To equip a new type of portable electric refrigeration HPGe gamma spectrometer system and applying it to the field of radiation monitoring. Methods Introducing the portable electric refrigeration HPGe gamma spectrometer system on the aspects of system structure and supporting, and calibrating the system in energy and efficiency. Results This system has the characteristics of portability, high intelligent, and good line energy. We obtained the accurate efficiency calibration curve, which makes radionuclide content in environmental samples analysis more quickly and accurately. Conclusion The portable HPGe gamma spectrometer system has a very good prospect for the application in radiation monitoring, and it can play an important role in the nuclear emergency monitoring.
