Personal Radiation Detector

γ -Tracer GT2-1

Personal Radiation Detector (PRD) γ-Tracer Model GT2-1 is a pocket-size device with built-in high sensitive room temperature operating semiconductor CdZnTe detector. The PRD can be used as a dosimeter to detect, measure and locate gamma-radiation sources. In case of the radiation danger, the PRD alerts a user by vibration and/or audible and/or visual signals.

The PRD γ-Tracer is an energy-compensated device allowing accurate evaluation of the dose rate and dose equivalent of the X-ray and gamma radiation. It automatically monitors environment and alerts user in case of the radiation threat. The device allows setup the alarm levels and updating background calibration for operation in changing radiation environments.

An intelligent search mode algorithm RiSearchTM provides fast response time and allows detecting a nd locating low-intensity gamma-radiation sources.

The device has a shock, dust and splash-proof case and LCD screen with backlight for operation in unfavourable environment conditions. It can be carried in the pocket or clipped to a belt.

Up to 3000 events and data samples can be recorded and stored in a non-volatile memory. The PRD γ-Tracer is capable to communicate with PC via USB port. The user software package “GT2-1 Configurator” is made to facilitate quick runtime parameters setup and has graphical tools for data log analysis.
