The invention belongs to the technical field of radioactivity monitoring, and in particular relates to a γ-
ray scanning imaging and
nuclide identification system and method thereof, comprising an outer casing arranged on a Y-axis turntable, the Y-axis turntable is arranged on the X-axis turntable, and the Y-axis turntable is driven to drive the Y-axis turntable. , the motor driver of the X-axis turntable, the probe with a
tungsten shielding shell arranged in the outer casing, the multi-channel analyzer connected with the probe, which also includes a
collimator that can be replaced, one end of the
collimator is connected to the probe, and there is A collimation hole with a specific collimation angle; a camera and a
laser range finder arranged in the outer casing and close to the probe, the axis of the lens of the camera and the
laser emitted by the
laser range finder are parallel to the axis of the collimation hole; also includes a connection motor The
motion control card of the driver connects and controls the camera,
laser rangefinder, multi-channel analyzer and the internal computer of the
motion control card; it has the advantages of large scanning range,
fast scanning speed, and can calculate the actual
dose value of each point in the measured area .
