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 using almost any common MCA employing regions of interest or peak-fitting routine of the user's choice. A wide variety of data entry possibilities is available, from fully manual data entry to an automatic mode where the user enters all necessary data in a tabular formal and the computer calculated the results. The resulting data can be automatically imported into a LOTUS 1-2-3 compatible spreadsheet for statistical analysis. All of the features of previous versions of NADA have been retained. These include a variety of methods for dead-time correction, correction of spectral and nuclear interferences, and a complete, concise hard-copy output. Future improvements include a routine which will automatically select regions-of-interest for spectra in ORTEC Maestro, thus reducing the processing time needed.
