Abstract
At the Interfaculty Reactor Institute the development of large sample INAA has been started. A facility is being installed in the reactor's thermal column for irradiation of samples with, sizes up to 100 cm in length, and 15 cm in diameter and weights up to 50 kg. A gamma-ray spectrometer with a very large semiconductor detector and sample scanning options will be used for measurement of the induced radioactivity. Algorithms are being developed to correct for the neutron self-shielding and gamma-ray attenuation problems.
