Radiation Reconnaissance Device

DRG-T

The board radiation survey device that generates signals and commands for crew life support systems.

The device is designed for installation in special-purpose vehicles, in particular in radiochemical reconnaissance units of civil defense, and armed forces. It is used for continuous monitoring of gamma radiation exposure dose rate. DRG-T provides audio and visual alarms of dangerous levels of gamma radiation and generates commands to start the actuators of protection equipment.

The device is endowed with high shock and vibration resistance.
