Abstract



A theoretical model has been developed for prediction of thermal neutron fluxes required for cyclic irradiations of a sample to obtain the same activity previously used for the detection of any radionuclide of interest. The model is suitable for radiotracer production or for long-lived neutron activation products where the background activities have half-lives ten times less than the activity of the radionuclide of interest. For selected irradiation conditions of timing of the repeated and single irradiation, the calculated results of thermal fluxes for various cycles and periods are discussed in the paper.
