The present invention is capable of determining the location(s) of waste (e.g. nuclear fuel debris, obstacles, contaminated or otherwise radioactive materials), monitoring and inspecting their surroundings, and transporting them, as well as use in repair, construction, and reactor decommissioning work in high radiation environment. Ultrasound (or sound) waves are not subject to interference from radiation. This modality is utilized in the present invention to detect and image waste and/or objects of interest. The system combines the resulting ultrasound (or sound) wave images for detecting waste and/or objects of interest with radiation information acquired by a radiation detector, to generate and adjust new composite images to display. For example, the image in the direction of strong radiation is red and the image in the direction of weak radiation is blue. Additionally, the constituent imaging apparatus may be fitted on a drone or robotic system for repair and construction work.
