Area Specific Stripping of Nordic AGS and CGS data, Final report

This report describes the results from a NKS (Nordic Nuclear Safety Research) project aiming at examining the possibilities for extracting stripping factors for Airborne Gamma-ray Spectrometry (AGS) data and Carborne Gamma-ray Spectrometry (CGS) data directly from the recorded set of data, i.e. without having to calibrate the detector systems on beforehand.

The project has been carried out between 1 August 2004 to 31 March 2005 by a research group composed of persons from Technical University of Denmark (DTU), Danish Emergency Management Agency (DEMA), Geological Survey of Sweden (SGU), and Norwegian Radiation Protection Authority (NRPA). AGS and CGS data from Sweden, Norway, and Denmark have been examined with the ASS method.

The project has been supported economically by the Nordic Nuclear Safety Research (NKS). The data sets used for the project, described in this report, have been recorded by SGU (Geological Survey of Sweden), DEMA (Danish Emergency Management Agency), NGU (Geological Survey of Norway), and SSI (Swedish Radiation Protection Institute).
