The study on stability and reliability of the nuclear detector

摘要：

Because of measurement environment and its own performance defect, the poor stability of nuclear radiation detector used on portable nuclear instrument leads to spectrum drift and decrease of energy resolution, which causes reduction of the detect efficiency. This results in lower measurement precision and accuracy of the system. Generally, the stabilization method based on hardware and software was applied. It is difficult to solve the problem about Spectrum drift caused by multiple factors. To slove the nonlinear problems caused by interference source, Multi-sensor Data Fusion Technique is adopt to design the intelligent nuclear detector with the Self-compensation Technique. It shows that the results of the project can improve the stability and reliability of the fieldwork measurement in system of the nuclear instruments. Except that it will improve the adaptive ability of the nuclear instruments to measuring environment.
