Data fusion from disparate sensors significantly improves automated man-made target detection performance compared to that of just an individual sensor. In particular, it can solve hyperspectral imagery (HSI) detection problems pertaining to low-radiance man-made objects and objects in shadows. We present an algorithm that fuses HSI and LIDAR data for automated detection of man-made objects. LI...

The study was performed in two areas of Sweden respectively with high natural radioactivity background (County of Jämtland), and high Cs deposition area deriving from Chernobyl fallout (County of Uppsala). Aims of the study were the calculation of activity concentration and transfer factors for all 6 radionuclides in the two areas and analysis of influence of soil characteristics on radionuclid...

program has been successful in making available to the community natural matrix materials that are very useful for the evaluation of radiochemical-measurement techniques. Traditionally, measurements of environmental radiological contamination have focused on the determination of total concentrations, a very useful tool for initial site characterization of impacted areas. It is clear, however, t...
