Abstract: A method and device for detecting radioactive sources is disclosed. In one aspect, an example method includes measuring, by a detector, a count rate curve of an inspection object while the inspection object moves through the detector. Pattern recognition is performed on the count rate curve. Whether there are radioactive sources in the inspection object is determined according to a result of the pattern recognition, and if there are radioactive sources in the inspection object, a type of the radioactive sources is determined.
