Software and Hardware System

GeoRad-M

The system is used to construct mobile radiological or radiochemical laboratories. It is fixed on the vehicle.

GeoRad-M consists of the BDBG-09 gamma radiation detecting unit (other detecting units with a similar exchange protocol are possible), the BS-09 Geo unit, a GPS antenna and custom-made software “GRad”.

GeoRad-M is intended to measure ambient dose equivalent rate of gamma radiation with reference to geographic coordinates (obtained from the navigation satellites). The results of measurements are displayed on a geographical map on the screen of a personal computer.

To obtain information about our products during the preparation of tender or contractual documentation, please contact our representatives via the provided contacts. We continuously improve our products and expand their functionality in line with market needs by applying the latest technologies, modern components, and materials. Therefore, specifications, descriptions, and configurations are subject to change without prior notice.

Features

Records measurement results of gamma radiation DER, as well as geographic coordinates and measurement time with an one second interval
Displays measurement results on the PC screen as a text and as route points linked to a geographic map. There are two modes of displaying / saving information – in a specified time or when moving to a given distance
Two threshold levels can be set – the warning threshold level and the danger threshold level of gamma radiation DER
Signals when the measured DER exceeds the set threshold levels with sound signals and a change in the color of information displayed on the PC screen and with light and sound alarm on the BS-09 Geo unit
Signals failures of the detecting unit and the BS-09 Geo unit with sound signals and messages on the PC screen. Sound signals about exceeding threshold levels and equipment failure are also generated by the PC acoustic system
Works with OpenStreetMap, Google Maps and Google Earth electronic maps

Purpose of Use

Measure ambient dose equivalent rate (DER) of gamma radiation and receive geographic coordinates from the navigation satellites
Display measurement results linked to a geographical map on the screen of a personal computer (PC), as well as archive this information

PC requirements

Operating system Windows 10 and later.
Other specifications of PC and PA (resistance and strength to mechanical and climatic factors, supply voltage and power consumption, screen size, etc.) must meet the requirements set for the mobile laboratory.
