Story: Radioactive minerals
Hans Geiger was the German inventor of the Geiger counter, which detects radiation. He is shown here in a laboratory at Manchester with Ernest Rutherford (right), the New Zealand scientist who split the atom. In the 1940s Ernest Marsden, a former student of Rutherford and colleague of Geiger, initiated a search for uranium in New Zealand.
