The installations are designed for continuous monitoring of the radiation situation at specified points of radiation objects with data transmission via VHF radio frequency channel and/or GSM/GPRS network. Purpose: radiation monitoring of industrial sites of nuclear power plants and other radiation facilities (RCP); radiation monitoring of the environment of sanitary protection zones and observation zones (RCOS); creation of an automated system for monitoring the radiation situation (ASKRO) of territories, sanitary protection zones (SPZ) and monitoring zones (ZN) of radiation-hazardous objects; creation of situational crisis centers (SCC) of enterprises and regions.

The fast-deployable radiation monitoring system (BR ASKRO) is intended for the operational creation of a local autonomous automated network of portable radiation monitoring posts in places where radiation emergencies occur. The main purpose of the system being created is continuous radiation monitoring, on areas up to 1 km2, when performing work to localize accidents and eliminate their consequences to ensure the safe operation of personnel of emergency rescue units, as well as to monitor the effectiveness of the work performed.

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
