Abstract

A major aim of the ECCOMAGS-RESUME2002 exercise was to perform direct inter-comparisons between airborne systems and ground-based measurements as part of the validation process for Airborne Gamma Spectrometry (AGS) procedures for measuring deposited activity and environmental dose rates. The exercise was preceded by ground-based pre-characterisation of three calibration sites in November 2001. A composite mapping task was also undertaken as a demonstration of the compatibility of results between AGS teams and the exceptionally high rates of survey that are possible using many aircraft. It has resulted in the collection of an unrivalled set of contemporary AGS and ground based measurements, and facilitated systematic comparisons between the major methods for measuring activity and dose rate in the environment.

More than 150 people, from 18 institutions and 10 European countries participated in the exercise and more than 120000 NaI(Tl) and 20000 Ge spectra were registered by AGS systems. This document is the final report on the exercise outcomes and contains a report on the intercomparisons conducted, reports from individual teams who participated in the exercise and the results of the pre-characterisation work and composite mapping tasks. The data sets have verified that the AGS technique is capable of producing data that are self-consistent and compare favourably to conventional ground-based approaches. Thus the AGS measurement protocols can be considered to have been verified relative to ground based methods. The comparisons also reveal detailed features of the measurement methods and their interactions with environmental variations under real field conditions.
