Abstract
Inorganic phosphor screens that are normally designed for low-energy x-ray imaging applications are shown to be useful for imaging with photons and neutrons having MeV energies. Characterizations of a number of commercially available phosphors with regard to detection efficiency for radiation type and energy, effective spatial resolution, optical self-absorption, response time, and spectral emissions are tabulated. Applications to high-energy x-ray imaging, nuclear fuel rod imaging, and nuclear fusion source imaging are shown to be feasible.
