Plastic Scintillating Fibers (PSF)

Plastic Scintillating Fiber (PSF) is a type of plastic optical fiber developed by Kuraray in the 1980s using a proprietary manufacturing process for radiation detection applications. It features a multilayer structure in which the core (inner layer) is made of polystyrene resin containing a fluorescent agent, and the methacrylate cladding (outer layer) consists of one or two layers. This structure enables the fiber to emit light when stimulated by radiation.
