Product details


Fig. 1 TK-206 neutron-gamma personal dosimeter

. 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.

. 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
