[0003] Radiation monitoring equipment is mainly used to monitor and supervise radioactive materials produced by radiation objects or radiation sources. Since radiation has a great impact on the human body but cannot be observed by the naked eye, it is generally necessary to use radiation monitoring equipment to detect the objects to be detected.

[0004] Existing monitoring equipment usually places radiation detection instruments on rotating platforms and mobile platforms to perform full-scale scanning of goods during the inspection process. This method is inefficient and requires a large number of driving electronic control components. In the scanning process, due to the lack of control over the scanning light source, the radiation detection instrument is placed on the rotating platform and the mobile platform to perform full-scale scanning of goods.
