Abstract: The 230U decay series, coupled to target-selective carrier molecules, has been identified as a candidate tool for targeted alpha therapy (TAT). The alpha branching ratios, half-lives and energies for the major peaks of 230U and its progenies have been deduced from only few experiments performed more than three decades ago. It was necessary to up-date these fundamental nuclear data and perform more accurate radiometric measurements that needed high quality 230U alpha sources. The objective of this work was to prepare 230U alpha sources with excellent spectral properties - high resolution, low tailing - and relatively high specific activity in order to accurately determine the relative alpha emission probabilities and half-lives via high-resolution alpha-particle spectrometry. The demands for source quality in radionuclide metrology are much higher than in applied spectrometry, e.g. for environmental analysis or geological studies. To achieve this, very thin and uniform 230U alpha sources have to be prepared.
