Abstract :
New personal computer (PC) software which performs interactive analysis of alpha spectra using enhanced graphics adapter graphics is described. Spectra are collected with a commercial MCA (multichannel pulse height analyzer) board and analyzed using the software described. The operator is required to approve each peak integration area before analysis proceeds. Sample analysis can use detector efficiencies or spike yields or both. Background corrections are made and upper limit values are calculated when specified. Nuclide identification uses a library of up to four nuclides with up to eight alpha lines for each nuclide. Any of 32 subset libraries can be used in an analysis. Analysis time is short and is limited by interaction with the operator, not only by calculation time. Utilities include nuclide library editing, library subset editing, energy calibration and background update.<>
