Innovative Laser remote analysis combined with Radiation resistant optical fiber based laser induced breakdown spectroscopy (Fiber LIBS) and laser ablation resonance absorption spectroscopy (LARAS) are developing for elemental and isotope analysis of nuclear debris in the on-site hot cell facility at the Fukushima Daiichi Nuclear Power Station. LIBS by long-pulse laser, Microwave assisted LIBS for higher sensitivity and Microchip laser use LIBS (MC-LIBS) for more flexible and easy light delivery, are also under developing for high performance surveillance.
