High Volume Radiation Detector Using Si Thin Films and Flexible Substrates

This ASU group proposes to capitalize on their experience with x-ray detectors, circuit design, focused ion beams, and thin ion-cut silicon slices to design a unique detector. We propose to detect heavy metals in the atmosphere and in soil (e.g., uranium, selenium). All of these compontents and concepts can be tested with standard components to enable realistic feasibility studies to be done. This work will ultimately enhance the security of miliary personnel in holstile encounters by providing the capability for the remote detection of elemental signature of radioactive and bio threats e.g. dirty bombs. This technology can be easily adapted to hand-held detectors to monitor the security of airports and borders.
