preparation of thorium nitrate was more effective in separating radiothorium from

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 ...
