Fig. 1 TK-206 neutron-gamma personal dosimeter
Ⅰ. Product Introduction
TK-206 is a gamma personal dosimeter using CsI crystal as the detection unit, as shown in Figure 1. Compared to the traditional electronic personal dosimeter, its sensitivity is higher more than 1,000 times. A special energy compensation design effectively guarantees the reliability of measurement results. A unique noise reduction circuit design is used, making the lower energy detection limit down to 20keV.
Ⅱ. Main Features
l High-density scintillation crystal is used as a detector, with high sensitivity, to measure the environmental radiation level;
l A unique noise reduction circuit design is used, making the lower limit of energy detection than that of the general personal dosimeter, with the lower limit up to 20keV;
l Energy compensation design is used, providing high data reliability;
l To support networking and GIS, and to achieve the intelligent and networking measurement of the staff dose and site radiation
