SHEI is operating neutron radiography (NRG) facility, based on cyclotron neutron source. Imaging methods of both Gd converter based film and neutron Imaging-Plate are applied. However, these methods are also sensitive to gamma-ray. To avoid the influence of gamma-ray, an indirect imaging method of Dy foil activation and X-ray Imaging-Plate is evaluated.
