BGO crystal detector capable of being used for detecting ground gamma rays

The BGO crystal detector comprises a waterproof box, a photoelectric sensor, a signal processing and control system, a data transmission system and a high-voltage control system, the lower end of the photoelectric sensor is punched to be connected with a high-voltage interface and an SHV interface, the high-voltage interface is connected with the high-voltage control system, and the SHV interface is connected with the waterproof box. The SHV interface is connected with the signal processing and control system, the signal processing and control system is connected with the data transmission system, and the data transmission system uploads detection data to the cloud server. The detector has the advantages of being simple in packaging, good in sealing performance, high in detection efficiency, high in counting rate and the like, has a higher effective detection energy section, and widens the detectable range of the detector; data transmission is carried out through the distributed cloud server, so that data of
