WebRoku 1906 se Hahn přemístil zpět do Německa, tentokrát do Berlína na místní univerzitu. V Berlíně pokračoval ve výzkumu radioaktivity. Vytvořil si vlastní laboratoř, ve které později objevil ionium, mesothorium I (radium 228) a mesothorium II. Za objev mesothoria byl roku 1914 poprvé nominován na Nobelovu cenu za chemii.

At first, the concept of isotopes was introduced by Frederick Soddy in 1913. The term isotope is associated with radioactive decay. This radioactivity led to the radical modifications in Dalton’s atomic theory. There were two independent lines of the research which became evidence for the existence of isotopes. hinckley chemist opening times
