Bode, M. Blaauw, I. Obrusník] Profiles of thermal flux, epithermal flux, f and α have been determined for a multisample irradiation container in use with k0-based NAA. It could be concluded that for accurate NAA with the IRI-reactor, samples should be surrounded by at least two thermal flux monitors. Since f and α values were found to vary considerably between irradiations as compared to the variations within one container, the possibility of determining f and α just once for the irradiation facility used, and monitoring only the thermal flux in future irradiations, was ruled out. The use of average values for f and α within a container was shown to yield unacceptable inaccuracies mainly for Zr and U determinations. Akadémiai Kiadó, 1992 Bode P.
