Preparation of uranium-230 as a new uranium tracer

T. Hashimoto, Kazuo Kido, Takeshi Sotobayashi

Abstract

A uranium isotope, /sup 230/U(T=20.8 d), was produced from the /sup 231/Pa(..gamma..,n)/sup 230/Pa..-->..via..beta../sup -/decay/sup 230/U process with a bremsstrahlung irradiation on a protactinium target. After standing for about one month to obtain a maximal growth of /sup 230/U, the uranium was chemically purified, applying an ion-exchange method. The purity of the /sup 230/U obtained was examined with alpha spectrometry and an intrinsic alpha peak due to /sup 230/U as a new uranium tracer in an alpha spectrometric analysis of uranium isotopes is described.
