AN ANALYTICAL SOFTWARE FOR NAA BY USING K_0- METHOD

摘要

An analytical software has been designed for a personal computer in DOS environment to do reactor NAA by using K_0-method. The system has functions of radionuclide identification, f and α calculation, K_0-value calculation, quantitative calculation of elemental concentrations, nuclides' data management, experiment design,computer simulation etc. The analytical methods used in this system include absolute method, relative method and K_0-method. Using this system, three gamma-ray spectra for NAA of Au, Zr samples and GBW07107 rock standard sample have been analyzed. The analysis results are in agreement with the certified results in the scope of uncertainties and the f and α values at the irradiation site in the UZrH pulse reactor are 36.6 and 0.044 respectively.
