Vision System for Monitoring and Sorting of Radiological Sources

The project uses new technology and methods not existing currently in the market. Conventional area radiation monitors are very limited in sensitivity, functionality and overall performance compared to the proposed new technology. Existing systems with higher performance are heavy-weight (20kg to 50kg), limited in functions (either spectroscopy only, or imaging only, or dose rate only) and require long setup time (several hours, e.g. due to cooling with liquid nitrogen). The main innovation is to use room-temperature operated single photon detection and imaging systems that are based on electronic collimation, so-called Compton collimation, and not based on the conventional mechanical collimation. The concept of Compton collimation uses the Compton scatter interaction of the gamma radiation in the detector and calculates from the acquired data for every incoming gamma photon the direction with respect to the detector. The absence of the conventional mechanical collimator means that the new system will be compact and light-weight and much more sensitive to radiation from all directions. We are aiming at serving 2 markets that are equally important to us: - Hospitals that apply various radiopharmaceutical procedures and cyclotron and reactor facilities that synthesize radiopharmaceuticals that will be served with fixed installations of RAS system and - Nuclear power plant decommissioning market that will use portable version of the RAS system.
