The nuclear detector is a key component in the reliability of nuclear radiation monitoring. It faces possible accident that involves high risks due to frequent operation in a radiation environment, which seriously affects the measurement accuracy. To ensure the detector reliability, a method for diagnosing scintillator detector fault based on the K-nearest neighbor (KNN) algorithm was proposed in this paper. The key points in a pattern recognition are the extraction of nuclear detector fault characteristic signal and how to establish fault diag...
