Abstract

A 15m-long plastic scintillation fiber (PSF) detector has been applied to the on-line evaluation of spatial dose-distribution inside the room of alow power research-reactor. It was found that the present PSF detector has enough performance as the real-time measurement system whichis not only quick and simple but also reliable for monitoring use inthat situation. Such application may bealso useful at the medical fields which routinely use radio isotopes for diagnosis purposes (suchas PET facility). From the present observation, it seems that the practically-acceptable maximum limit of PSF length isat most15 m. More than this, the severe signal reduction brings unavoidable difficulties for the following signal processing.
