Radiothorium

Hahn's radiothorium and actinium salts also followed him to Emil Fischer's laboratory in Berlin. 30 ❋ Unknown (2007)

Hahn had identified a new radioelement that emitted thorium emanation and which he labeled radiothorium. 28 Meanwhile, Soddy had moved to the Chemical Institute of University College in London to join Ramsay's research. ❋ Unknown (2007)

With Ramsay's consent, Hahn had taken with him the radiothorium he separated from samples of barium chloride and the actinium that he and a collaborator had earlier proved to be identical to the new element that the German chemist Friedrich Giesel had named emanium. ❋ Unknown (2007)

Other radioactive elements have been discovered since: actinium (Debierne), radiothorium and mesothorium (Hahn), ionium (Boltwood), etc. ❋ Unknown (1966)

On this occasion, we employed the energy-rich gamma radiation of a radiothorium preparation. ❋ Unknown (1964)

His work here was rewarded by the discovery of a new radioactive substance, radiothorium, while working on the preparation of pure radium salts. ❋ Unknown (1964)

Here he discovered radioactinium and conducted investigations with Rutherford on alpha-rays of radiothorium and radioactinium. ❋ Unknown (1964)

Many having other radio-elements are known already, the polonium, the mesothorium, the radiothorium, the actinium. ❋ Unknown (1921)
