ABSTRACT
This chapter includes early papers written in New Zealand, at the Cavendish Laboratory and during the Montreal period (1894-1906), as well as an introduction to Lord Rutherford's early work by Sir Edward Appleton, and some reminiscences of his time in Canada by Professors H. L. Bronson and Otto Hahn. The method adopted depended on the preparation of a Standard solution of radium bromide and the amount of radium emanation formed in it was compared with that formed in a radio-active mineral containing a known quantity of uranium. The Standard solution was prepared by Rutherford and Eve. The crystal of radium bromide was then dissolved in distilled water and by successive dilutions solutions were prepared to contain 102, 104, and 106 milligram of radium bromide per cubic centimetre. The leak corresponding to the equilibrium quantity of radium emanation formed by the radium associated with 1 gr. of uranium in a natural mineral was next determined.
