European Calibration and Coordination of Mobile and Airborne Gamma Spectrometry (ECCOMAGS)

Project ID: FIKR-CT-2000-20098
Funded under: FP5-EAECTP C

Abstract

Airborne Gamma Spectrometry (AGS) utilises highly sensitive radiation spectrometers mounted in low-flying aircraft to record variations in terrestrial radiation fields. The combination of high fields of view (104-105 m2), rapid measurement (1-10s per measurement) and high detector mobility (30-50 m s-1) results in area sampling rates (107-108 m2hr-1) which are many orders of magnitude higher than can be achieved using conventional ground-based measurement methods. In recent years the number of AGS teams in Europe has increased and the techniques and instrumentation have advanced considerably, including developments in software systems making it possible to analyse survey data in real time or near real time. The ability of the method to map deposition rapidly over large areas has been established by work conducted individually by AGS teams in Europe and elsewhere. The ability of teams to work together producing compatible results despite diversity of equipment and methods, and to produce results which are quantitatively traceable to ground-based measurements, was the focus of this project. As a result of the ECCOMAGS project, the validity of the AGS method, which has vital importance of emergency response, can now be clearly demonstrated.
