Toward the decommissioning of the Fukushima Daiichi Nuclear Power Plant, a real-time remote detector using an optical fiber and a small scintillator was developed for radiation distribution measurement under high dose rate conditions. Mo-substituted Cs₂HfCl₆ was synthesized as the scintillator, and near-infrared emission at approximately 900 nm, within the target emission wavelength range, was confirmed.
