 note = {Radiation dose rate effects to the properties of a compact fiber-optic laser-induced breakdown spectroscopy (LIBS) system with a monolithic Nd:YAG/Cr:YAG composite ceramics were investigated for remote analysis in hazardous environment. To investigate radiation effects to the system, properties related to the Nd:YAG laser operation were measured as a function of the radiation dose rate from 0 to 10 kGy/hr such as oscillation threshold, output energy, oscillation timing, temporal pulse shape, and beam profile in view of their influences to LIBS signal. LIBS spectra of zirconium metal were measured under irradiation. Although signal intensity decreased considerably by irradiation, informative spectra were well observed even at the maximum dose rate. From the comparison of the LIBS related parameters among the laser properties, the signal reduction was mostly ascribed to the pulse energy reduction. Scintillation emission spectra were also measured from the ceramice during the irradiation, and the signal intensity increased linearly with the dose rate. The results show that the developed system is applicable to the efficient remote elemental analysis and also radiation dose rate monitor in hazardous environments such as for nuclear fuel debris inspection.},
