Elemental analysis of two Egyptian iron ores and produced industrial iron samples by neutron activation analysis

Elemental analysis of two iron ores and initial industrial iron production prepared by the Egyptian Iron and Steel Company of Helwan near Cairo were p erformed by the instrumental neutron activation analysis technique. Five sa mples of each type were irradiated for 48 h in a thermal neutron flux of 4 x 10(12) n/cm(2)s in the first Egyptian research reactor ET-RR-1, Also, the Pneumatic Irradiation Rabbit System (PIRS), attached to the reactor ET-RR- I in Inshass, was used to measure short-life elements. The gamma -ray spect ra were obtained with a hyper pure germanium detection system. The concentr ation percentage values of major, minor and trace elements are presented. I mplications of the elemental concentration values obtained are presented. ( C) 2001 Published by Elsevier Science Ltd.
