摘要
A review is presented of recent development of phosphors and scintillators for X-ray and thermal neutron radiation imaging detectors. Data is presented on an improved range of X-ray intensifying screens constructed from Gd2O2S:Tb, which shows a shift in the expected trade-off line for resolution versus light output. A high uniformity CsI:Tl fibre optic sensor is also presented. In addition, a new high (LiF)-Li-6 formulation of neutron detection screen is described, as well as recent radiation imaging detector projects using Li-6 glass scintillators. (c) 2005 Elsevier B.V.
