    "abstract": "An intense 146 MeV/c pion beam was stopped inside a scintillating fiber\ndetector made out of 12 planes with 16 pixels each, where every pixel consists\nout of 8 times 8 scintillating fibers of 500 mkm diameter dense packed. The\ndetector was irradiated for 52 hours to more than 1 Mrad at its center. Before\nand directly after the irradiation the detector has been exposed to a particle\nbeam to compare the corresponding light output. This study was continued during\nthe following three months using cosmic rays. No damage was found taking into\naccount the measurement errors of 5-10 %. In contrast a 9 cm deep lucite\ndegrader became irreversibly non-transparent in the irradiation region.",
