Abstract: Elemental analysis of iron ore samples and first industrial iron
production prepared by the Egyptian Iron and Steel Company of Helwan near Cairo
were determined by instrumental neutron activation analysis technique. Five
samples from each kind were irradiated for a 48 hours at a thermal neutron flux
of 4x10¹²n/(cm²·s) in the first Egyptian research reactor
ET-PP-1. Also the pneumatic irradiation rabbit system (PIRS) attached to the
reactor in Inshass, was used to measure the elements of short-life time.The
gamma-ray spectra were recorded by means of the hyper pure germanium detection
system. The concentration percentage values of major, minor and trace elements
are presented. The long and short lived isotopes were considered. A comparative
study and a discussion on the elemental concentration values are given.
