摘要：

A method based on internal standard is proposed to correct the thermal neutron self-shielding effect of aqueous samples containing elements with large thermal neutron absorption cross-section using prompt gamma-ray neutron activation analysis. The experiments for determination of boron and cadmium dissolved in water were carried out to validate the method using a setup with a 300 mCi Am-241-Be source and a cylindrical 4 x 4 inch (diameter x height) BGO detector. The results showed the proposed methodology can be used to correct the self-shielding effects for the aqueous samples by prompt gamma neutron activation analysis.
