摘要：

Measurement of neutron flux micro distribution within absorbing samples have been made using Dy and Au foils activated in cadmium filter for both thermal and epithermal regions, respectively. Self-shielding effect for highly absorbing material has been investigated for the purpose of activation analysis in the Syrian Miniature Neutron Source Reactor (MNSR). Self-shielding factors for both thermal and resonance regions have been evaluated. Measured and theoretical values of self-shielding factors have been compared. Correction expression of the neutron activation analysis measurement for self-shielding has been proposed.
