Scintillators around us

Ing. Vítězslav Jarý, Ph.D., Ing. Jan Pejchal, Ph.D. (Fyzikální ústav)

In recent years, number of industrial, medical, safety and scientific applications, in which invisible ionizing radiation (e.g. gamma-rays, X-rays) has to be detected, have been developing rapidly. This booklet deals with the description of scintillation materials that are suitable for this purpose. Scintillation materials convert the energy of high-energy ionizing radiation into ultraviolet (UV) or visible photons, which can then be converted into an electrical signal by conventional photodetectors and further processed. Among the best known scintillation applications are computed tomography (CT), positron emission tomography (PET), LHC particle accelerator detectors in European Center for Nuclear Research (CERN), or modern monitoring unmanned drones used around Fukushima nuclear power plant in Japan.
