Description	Journal: Applied Physics Express We have developed a remote scintillation detector using a CCD spectrometer and a red-emitting scintillator coupled with a 20-meters optical fiber for ultra-high-dose condition. Gamma-rays were detected with a conventional deep-red-emitting ruby scintillator and $Cs_{2}HfI_{6}$ which is a novel material with 700-nm red emission and a high light output. The scintillators were irradiated with gamma-rays from a$ ^{60}$Co source under the effective dose rate from ~0.002 to ~1 kSv/h. The integrated area of the $Cs_{2}HfI_{6}$ emission spectra was larger than that of the ruby, and the good linearity of $Cs_{2}HfI_{6}$ signal as a function of dose rate was confirmed.
