Der gegenwärtige Stand der Radioaktivität.

(Leipzig, S. Hirzel, 1906). No wrappers. In "Jahrbuch der Radioaktivität und Elektronik", 3. bd., Heft 1. Pp. 1-116 (entire issue offered). Soddy's paper: pp. 1-23.

Importent early survey of the investigations into the radioactive elements.

Soddy developed with Lord Rutherford during 1901-1903 the disintegration theory of radioactivity, confirmed with Sir William Ramsay in 1903 the production of helium from radium, advanced in 1910 the concept of isotope, proposed in 1911 the alpha-ray rule leading to the full displacement law of 1913, and was the 1921 Nobel laureate in chemistry, principally for his investigations into the origin and nature of isotopes.
