Ⅰ. Product Introduction
The TK-204 portable high-purity germanium spectrometer is a high-performance, highly integrated gamma radioactivity measuring device developed as adapted to field measurement requirements (see Figure 1). TK-204 integrates HPGe detector, liquid nitrogen refrigeration unit, multi-channel electronics, energy spectrum analysis software and sourceless efficiency calibration software, military reinforcement data acquisition and processing terminal. As the Gamma-4 sourceless efficiency calibration software based on CAD model is used, the quantitative efficiency calibration is made for the measurement object of any shape made of any base material, making that the system has a strong field Application ability. Figure 2 shows a superior field measurement capacity of Gamma-4 sourceless efficiency calibration software.
Ⅱ. Main Features
Quantitative measurement of activity of radioactive source of any shape and any base material;
l Full Chinese interface, automatic energy spectrum analysis software is provided, so even non-professional can quickly grasp this;
l With more than 3000 kinds of isotope ray information provided, nuclide library and energy spectrum analysis software are combined firmly, user-friendly.
l Multi-channels all use military-grade devices, with high reliability; the entire machine can be replaced in case of failure;
l Detector can be replaced by a spare one stored in the company, to ensure recover within 72 hours.
