NADA92 - AN AUTOMATED, USER-FRIENDLY PROGRAM FOR NEUTRON-ACTIVATION DATA-ANALYSIS

We have developed a highly automated program for the analysis of data from neutron activation analysis (NAA). Spectral analysis is done usin g almost any common MCA employing regions of interest or peak-fitting routine of the user's choice. A wide variety of data entry possibiliti es is available, from fully manual data entry to an automatic mode whe re the user enters all necessary data in a tabular formal and the comp uter calculated the results. The resulting data can be automatically i mported into a LOTUS 1-2-3 compatible spreadsheet for statistical anal ysis. All of the features of previous versions of NADA have been retai ned. These include a variety of methods for dead-time correction, corr ection of spectral and nuclear interferences, and a complete, concise hard-copy output. Future improvements include a routine which will aut omatically select regions-of-interest for spectra in ORTEC Maestro, th us reducing the processing time needed.
