A mobile gamma ray spectrometer system for nuclear hazard mapping: GAMMALOG v. 3.0

The Geological Survey of Norway has developed a system for mobile gamma ray spectrometer surveying suitable for use in nuclear emergencies where potentially dangerous radioactive materials have been released into the environment. The measuring system has been designet for use with different kinds of transportation platform. These include fixed-wing aircraft, helicopters and vans/cars. The choice of transportation platform depends on the nature of the nuclear emergency. Widespread fallout from a distant source can be mapped quickly from the air while local sources of radiation can be delineated by a carborne system. The measuring system processes gamma ray spectra in real-tome. The operator of the system is therefore able to guide surveying in accordance with meaningful data values and immediately report these values to decision-making authorities. The operator is presented with a number of different displays suited to different kinds of nuclear emergencies that lead to more efficient surveying. Real-time processing of data means that the results of a sruvey can be delivered to decision-makers imediately upon return to base. It is also possible to deliver data via a live mobile telephone link or wireless network while surveying is underway. Forkortet. Frie emneord: Atomberedskap
