    Opis

    Przyrząd pokładowy do pomiaru promieniowania, który tworzy sygnały i rozkazy do systemów zabezpieczenia życia załogi.

    Przyrząd przeznaczony jest do montażu w środki transportu specjalnego przeznaczenia, szczególnie w jednostkach zwiadu radiochemicznego obrony cywilnej i w siłach zbrojnych. Używa się w celu nieustannej kontroli mocy dawki ekspozycyjnej promieniowania gamma. Także DRG-T zabezpiecza sygnalizację świetlną i dźwiękową o niebezpiecznym poziomie promieniowania gamma i wydaje rozkazy włączenia mechanizmów wykonawczych środków ochrony. Przyrząd posiada wysoką odporność uderzeniową i wibracyjną.

    Przeznaczenie

    • The DRG-T radiation survey device is designed for use in special-purpose vehicles to control continuously and measure exposure dose rate (EDR) of gamma and X-ray radiation, as well as to provide audio and light alarms of dangerous levels of radiation, and to issue commands to start the actuators of protection equipment.

    Właściwości

    • Highly resistant to shock and vibration.

    • Considers different attenuation degrees of gamma radiation.

    • Produces signals to display information on data panels of the vehicle.

    • Issues commands to start the actuators of crew protection equipment.

    • Ensures self-testing function of the device performance with and without commands issuing to the actuators.

    • Transfers data to the onboard computer.

    Podstawowe charakterystyki techniczne

     Measurement range of gamma radiation EDR from 1×10-5 to 1000 R/h.
     Energy range of detected gamma radiation from 0.66 to 1.25 MeV.
     Main relative permissible error limit during measurement of gamma radiation EDR (relative to 137Cs) with confidence probability of 0.95: Без названия5, where Без названия6 is a numeric value of measured EDR in miliroentgens per hour.
