ResumoThe half-life of protactinium-231 has been determined by a combination of total α-assay and α-pulse analysis using solutions prepared by dissolution of various protactinium penta- and tetrahalides in concentrated nitric acid. The specific activity of protactinium-231 is found to be 1·062 ± 0·0076 α dmin−1mg−1, equivalent to a half-life of 32,340 ± 230 years.
