Beschreibung
Zusammenfassung:	Provided is a collimator structure for a transmission radioactive source, comprising: a transmission radioactive source; the first shielding block is arranged on the emergent side of the transmission radioactive source and used for blocking rays emitted by the transmission radioactive source; the first collimation hole is formed in the first shielding block and penetrates through the first shielding block; and the driving device is connected with the first shielding block and is used for driving the first shielding block to move, so that rays emitted by the transmission radioactive source pass through the first collimation hole or are blocked by the first shielding block. The first shielding block can be driven by the driving device to move, so that the first collimation hole in the first shielding block is aligned with or not aligned with the ray beam emitted by the transmission radioactive source, and turn-off processing of the rays of the transmission radioactive source and the external environment is achi
