New developments in the field of robotics and computer vision enable to merge sensors to allow fast real-time localization of radiological measurements in the space volume with near real-time radioactive sources identification and characterization. These capabilities lead nuclear investigations to a more efficient way for operators dosimetry evaluation intervention scenarios and risks mitigation and simulations such as accidents in unknown potentially contaminated areas or during dismantling operations. In this communication we will present our current developments of an instrument that combines these methods and parameters for specific applications in the field of nuclear investigations. 1 Introduction Since the end of 2000s new emergent technologies in the field of video games and robotics enabled to consider fast Nuclear back-end activities such as decontamination and computations due to new embedded GPU and CPU dismantling lead stakeholders to develop new methods in architectures. Since the Microsoft Kinect has been released order to decrease .
