Display and control unit is designed to display information when operates together with the external smart probes, to program its operation modes and to identify radionuclide composition. Display and control unit cannot be used independently.
The instrument indicates the menu and measurement results, stores the accumulated scintillation spectra in its permanent memory, enables communication with PC as well as receives GPS information and transfers data via USB and Bluetooth interfaces.
Radiation Monitoring System PM520 is designed for continuous gamma and neutron radiation monitoring of different facilities where radioactive sources are stored or processed.
PM520 can be deployed in several separate locations or in passageways outdoors. Apart from other systems, PM520 has flexible configuration and uses up to 8 wall-mounted Gamma and Neutron Probes of different sensitivities and measurement ranges, main processing unit and remote PC for operation monitoring control with maximum distance between probes and unit up 1000 m. This configuration allows extending the range of controlled area with possibility of transferring measurement data to the single coordination center.
Radiation Monitoring System can be used in different areas: nuclear facilities, waste management, areas and buildings with limited access, border/airport check points, places of storage and use of nuclear materials.
Neutron radiation detector BDN performs the following functions: measurement of DER of neutron radiation in collimated radiation by Pu-α-Be, search and registration of neutron radiation sources.
BDN can be used by radiological and isotope tracing laboratories, customs officers, emergency services to search and detect neutron radiation sources and to continuously monitor radiation environment.

Personal radiation detector PM1401MA is designed for detecting of gamma radiation sources. Due to its hermetic and shockproof case and the LCD screen fluorescent backlight, instrument can be used in extreme and harsh environments. For work in difficult-to-access areas telescopic extension tube is provided. PRD has audible, visual and vibrating alarms, records and stores up to 1000 events in non-volatile memory and transmits data to a PC via USB interface.
PM1401MA is recommended for first responders, security guards, police, customs officers and border patrol. No special experience or training is necessary to operate the instrument.
