Novel remote sensor using an imaging plate and wavelength-shifting fibers for dosimetry of gamma rays and neutrons

A novel remote sensing method utilizing an imaging plate was developed for dosimetry of gamma rays and neutrons in reactor or accelerator facilities. One of important research theme for this method is to develop remote sensors because these dosimetries require the multi-point measurements. Therefore, we developed a remote sensor which consists of an imaging plate, band pass light filter, wavelength shifting fibers and side-emission-type light fibers for exciting an imaging plate. The remote sensor was optimized by selecting the bandpass filters. After the optimization, it is confirmed by the basic experiments that the PSL counts can be measured with good S/N ratio and are proportional to gamma-ray doses
