An intercomparison of the radium mass standards of the UK and the USSR
Abstract
The National Radium Standards of the UK and the USSR were intercompared by means of measurements of a secondary standard. In the UK the determination of the radium element content of the secondary standard was accomplished by gamma-ray spectrometric comparison with the national standard while in the USSR an ionization chamber and a calorimeter were used. Good agreement is obtained between the three methods. The results also agree with that of a comparison with the National Radium Standard of the USA.
