Symposium U, "Nuclear Radiation Detection Materials," held April 26-28 at the 2011 MRS Spring Meeting in San Francisco, California was a continuation of the 2009 symposium and provided the latest research in nuclear radiation detection materials. Types of detector materials include semiconductors and scintillators, which are represented by a variety of new scintillator materials; novel semiconductors; and traditional detection materials. There is a strong need for new materials and methods for a variety of radiation detection applications in this rapidly growing field. The symposium gave an...

The scope of detector materials for semiconductors and scintillators includes a wide variety of molecular compounds such as cadmium zinc telluride (CZT), lanthanum halides, and others. An additional class of scintillators is based on organic compounds and glasses. Ideally, attributes of materials used for radiation detection include appropriate-range bandgaps, high atomic numbers of the central element, high densities, performance at room temperature, strong mechanical properties, and low production cost. Unfortunately, there are significant gaps in the knowledge required to produce radiation...
