Abstract

A new internal reference method for activation analysis has been developed. The method can be used effectively for special samples in which suitable elements as internal standards are absent and the self-shielding effect can be neglected. In this method, Wb g of element B as an internal reference is added to the sample which contains Wa g of element A to be determined, whereas the comparative standard is prepared by mixing only the element A and B in a known concentration ratio of W a * /Wb. When the sample and comparative standard are irradiated by particles with the same energy distribution, even though both are irradiated separately by particles with different flux, Wa can be determined easily by the following equation.
$$W_a = \left( {{{A_R } \mathord{\left/ {\vphantom {{A_R } {A_R^* }}} \right. \kern-\nulldelimiterspace} {A_R^* }}} \right)W_a^* $$
where Ag and AR are count ratios between gamma-rays emitted by two radioactive nuclides produced from elements A and B in the sample and comparative standard, respectively. The usefulness of the present method was examined through the determination of Ti, Cr, Ni and Zr in several commercial aluminium alloys by means of photon activation, and the accuracy and precision of the method were verified.
