摘要：

Thorium and uranium have been determined by counting induced fission tracks. While for uranium determinations no chemical separation was required, the thorium was first separated using the strongly basic anion-exchange resin, Dowex 1 × 8, in a mixed medium consisting of 5M HNO3 and methanol. This was done by batch rather than column method. The feasibility of the method was established by analysing standard rocks. A precision of ±5-10 % and an accuracy of ±10 % were obtained. © 1979.
