ABSTRACT: Participation
in inter-comparison programs is an important process to enhance the accuracy and
precision of the analytical techniques used in the laboratories. At Es-Salam
Research Reactor, our laboratory uses two functional analytical techniques such
as INAA and k0-INAA in the research projects and for the completion
of the service works. Recently, our laboratory has participated in two
inter-comparison tests organized by IAEA within the framework of the AFRA
project to assess the analytical performance of eighteen (18) African
analytical laboratories participating in the RAF/4/ 022 project, Enhancement of Research Reactor Utilization and Safety by
taking part in analytical proficiency testing IAEA in conjunction with WEPAL,
the Wageningen Evaluating Programs for Analytical Laboratories. The Proficiency
Testing tests related to the determination of major, minor and trace elements
in materials of the International Soil and Plant Analytical Exchange (Wepal
codes ISE, IPE), were held in the fourth quarter of 2011 and the first quarter
of 2012, respectively. Concentrations of thirty (30) elements such as Al, As,
Ba, Br, Ca, Cd, Ce, Co, Cr, Cs, Fe, Ga, K, La, Mg, Mo, Mn, Na, Nd, Rb, Sb, Sc,
Sr, Th, Ti, U, V, W, Zn, Zr were determined in ISE and IPE samples. All results
were evaluated and reported in this paper.
