Use and benefits of gamma imaging for radiation protection

Full text: CORIS360® is an advanced gamma imaging system that offers new insight into complex radiation environments. It has been used in many scenarios which have aided decision making for the benefit of personnel safety and dose optimisation. The wide 360° x 90° field of view makes this imager ideal for radiation protection applications, being able to image wide areas and effectively reducing worker exposure to radiation. In addition, CORIS360® can simultaneously image different radionuclides over a broad 40 keV - 3 MeV range. CORIS360® incorporates interchangeable spectroscopic CLLBC (Cs₂LiLa(Br,Cl)₆:Ce) detector assemblies, which have different detector volumes and sensitivities. A 1.5 inch detector is ideal for imaging low to medium dose rate scenarios such as standoff imaging and background assurance imaging, whereas a smaller 0.5 inch detector is beneficial in higher dose rate environments, which could be used for hot cell contamination imaging or nuclear decommissioning projects. The lithium component in this scintillator detector allows for neutron detection, which is beneficial for nuclear security. The CORIS360® technology is also being further developed to image thermal neutrons, higher energy prompt gammas as well as lower energy photons, making it an important tool in enclosed beamline environments, such as neutron scattering facilities and particle accelerators. This presentation will exhibit radiation imaging case studies, demonstrating the benefits to radiation protection and safety when working in radiation environments. (author)
