A simple and reliable device for monitoring the radiation situation in rooms where work is carried out with radioactive sources (substances, medications, installations). If the set threshold value of the dose rate is exceeded, the device gives a sound and light signal, controls external devices (for example, door locking devices). Purpose: measurement of the ambient dose equivalent of gamma radiation (MAED); sound and light alarm about exceeding the set threshold; activation of external signaling or actuating devices.

The device gives out an electrical control signal when a gamma radiation flux with a gamma quantum energy of 1.25 MeV (200 FJ) is detected Parameters of the electrical control signal: - pulse duration of 0.1 – 0.6 sec.; - the amplitude of the pulse is equal to the value of the voltage of the on-board network. The time of setting the operating mode after the supply voltage is provided, is not more than 1 min The time of continuous operation of the alarm is at least 48 hours The signaling device is powered from the on-board DC voltage network. The power consumed by the alarm does not exceed 10 watts The alarm is resistant to impact of:  - high ambient temperature (+55°C) - low ambient temperature (-50°C) The alarm remains operational after exposure to:  - high ambient temperature (+70°C) - low ambient temperature (-65°C) The alarm is resistant to high humidity with a relative humidity of 100 % at a temperature of +35°C
