A PC-program for the calculation of neutron flux and element contents using the k(i)-method of neutron activation analysis

A computer program is described, which calculates the induced activities of isotopes after irradiation in a known neutron field, thermal and epitherma l neutron fluxes from the measured induced activities and from nuclear data of 2-4 monitor nuclides as well as the element concentrations in samples i rradiated together with the monitors. The program was developed for operati on in Windows 3.1 (or higher). The application of the program for neutron a ctivation analysis allows to simplify the experimental procedure and to red uce the time. The program was tested by measuring different types of standa rd reference materials at the FRJ-2 (Research Centre, Julich, Germany) and Triga (University Mainz, Germany) reactors. Comparison of neutron flux para meters calculated by this program with those calculated by a VAX program de veloped at the Research Centre, Julich was done. The results of testing see m to be satisfactory.
