During the comparative investigation of radiation fingerprint some current gamma spectrum analysis software are found to leave some drawbacks
which result in reduced precision of the radiation fingerprint comparison. We have therefore developed a new analysis software to solve the problem.In order to display the advantage of our program
some typical simulative warhead gamma spectra are analyzed by using our software and GAMMAVISION and GENNIE2000
respectively. The new software can be applied not only in nuclear warhead deep-cuts verification
