2. In situ measurements of radionuclide concentration in soil : An investigation into detector properties and methods
Abstract : In case of a release of radioactive nuclides into the environment it is necessary to have reliable methods to estimate the potential effect on people and the ecosystem. In this context the total activity deposited, the elemental composition and the depth distribution are of importance. READ MORE

5. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography
Abstract : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.
