Description

Technical Field

[0001] The utility model relates to the technical field of nuclear radiation detection, and more particularly to a nuclear decommissioning space radiation field modeling device. Background Art

[0002] During the decommissioning of nuclear facilities, workers are required to conduct on-site construction, where various radioactive objects may be present. Therefore, during decommissioning, equipment maintenance, and nuclear emergency response, 3D environmental scanning and spatial radiation dose imaging of the decommissioned nuclear facility construction site are performed to determine the spatial radiation dose distribution within the nuclear radiation operating environment. This helps construction workers visually locate radiation sources and assess construction work processes, thereby improving the efficiency of equipment and facility maintenance, nuclear emergency response, and decommissioning operations. Furthermore, it provides reliable data support for personal protection for workers.
