Features
① Adopting all-Chinese spectrum analysis and internal irradiation dose assessment software;
② Equipped with automatic spectrum stabilization, energy calibration, peak search, peak analysis, activity meter calculation, uncertainty analysis and other functions;
③ Gain and high voltage adjustment can be performed, real-time display of real time/live time, discrimination threshold and other functions can be displayed;
④ Built-in common radionuclide library, support users to add new nuclides independently;
⑤ Passive γ detection efficiency self-calibration can be achieved;
⑥ According to different options such as nuclides, metabolic time, age, tissues and organs, the influence of different factors on internal irradiation dose is fully considered, and the internal irradiation dose of each organ is estimated;
⑦ Automatically output measurement analysis report, support external printing;
⑧ Adopt chair-type measurement method, and the measurement height and angle are adjustable.
