| Abstract | The results of an international comparison of activity measurements of a solution of ²³¹Pa are reported and analysed. Prior to this, no known standardisation of ²³¹Pa by activity measurement had been carried out. The comparison was run in 2017–2018 involving eight laboratories, and returned results with no identifiable inconsistencies between methods or laboratories. The results, including one mass determination, gave a²³¹Pa activity concentration of 41.461(48) kBq g⁻¹ and a²³¹Pa atom concentration of 61.48(23) × 10¹⁵ atoms g⁻¹, from which a half-life value of 32 570(130) years was derived. |
