Abstract
Instrumental neutron activation analysis (INAA) using rabbit irradiation system at ETRR-2 reactor was utilized to analyze some elements namely Na, Mg, Al, Cl, V, Mn, In, and Br in four different crude petroleum samples from different oil fields in the Suez-Gulf region of Egypt. The INAA was performed by four different standardization methods. Namely absolute, single comparator based on effective cross section concept, single comparator based on
k
0,Au factors, and that based on
k
0,ic factors defined versus any suitable internal comparator method. A FORTRAN computer program was written to calculate the extracted concentrations by these methods. A reasonable agreement between the obtained results was noticed.
