An intercomparison of the radium mass standards of the UK and the USSR: 2
Abstract
A comparison of national radium standards of the UK and the USSR as part of bilateral cooperation in the field of activity measurements is presented. The measurement methods for calorimetric and ionometric comparisons are described. Tables show: observed counting rates in the 1764 keV photopeak together with calculated source transmissions; analysis of individual uncertainty components arising in the determination of the radium content of X5; and calculated mean energy components. The results of all measurements, decay corrected to a common reference time of 1 Jan. 1989, are tabulated, and show that good agreement between the various methods of measurement employed in the intercomparison was achieved.
