It was the dawn of the nuclear age and scientists were still coming to terms with the discovery by the British chemist Frederick Soddy in 1913 of chemical “isotopes”. These are variants of chemical elements that have the same number of protons, but different numbers of neutrons – although neutrons were yet to be discovered.
