Applications of scintillators in optical-fiber-based detectors

This article presents the fundamentals and an overview of the optical-fiber-based scintillation detectors, which consist of a scintillator and an optical fiber light guide. This type of detector is preferentially used in special applications. In these applications, only a scintillator probe is placed in a severe environment, while a photodetector stays in a mild environment. Additionally, a detector should not disturb an irradiated field. As examples, applications in nuclear reactor physics experiments, medical uses, such as radiation therapies, and severe radiation conditions are reviewed.
