Description

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.

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

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
