ter sort contained the maximum or equilibrium amount of radiothorium, while the
former evidently did not. It seemed, therefore, as if the technical method of
preparation of thorium nitrate was more effective in separating radiothorium from
...

formed thorium X and some days after preparation gave oil" the thorium
emanation freely. There is no doubt that radiothorium is the direct parent of

The History of Early Nuclear Physics (1896-1931)
The period of decay of the new substance was found to be 737 days, very close
to Hahn' s value for radiothorium. This was an independent confirmation of the
discovery of radiothorium (8). The radiothorium was also separated from the ...

The Interpretation of Radium: And the Structure of the Atom
In a vessel containing a thorium or, better, a radiothorium preparation, which acts
as a constant source of the evanescent thorium emanation, the active deposit on
