Knowledge Based System for Identification of Gamma Sources

摘要

SHAMAN is an expert system for the qualitative identification of radionuclides inthe measured gamma spectrum. The goal of SHAMAN is to correctly identify all radionuclides in the sample and to quantitatively determine their activities and all related parameters. This report documents the SHAMAN system starting from the algorithmic level and ending with programming issues. The first three chapters give an overview of the initial problem of radionuclide identification and expert system concepts in general. Chapter 4 and 5 present the special programming interface of SHAMAN. The entire methodology of SHAMAN system ranging from fundamental algorithms to data processing is contained in chapters 6-10. The last chapter of the report is devoted to performance issues and conclusions presenting some test results.
