We have developed the advanced application method of optical fiber towards the radiation distribution measurement inside Fukushima Daiichi Nuclear Power Station (FDNPS). Position-sensitive optical fiber radiation sensors based on the photon time-of-flight and wavelength resolving analysis were introduced, and the advantage of both methods for the nuclear decommissioning application was discussed.
