As early as 1907 Bertram Boltwood had used the discovery of radioactive decay laws by Ernest Rutherford and Frederick Soddy to ascribe an age of over two billion years to a uranium mineral. Rydberg, J.; Liljenzin, J.-O.; and Choppin, Gregory R.

In 1940, at the University of California in Berkeley, Edwin Mc Millan and Philip Abelson produced the first manmade element, neptunium (Np), by the bombardment of uranium with low energy neutrons from a nuclear accelerator. There are essentially three sources of radioactive elements.Primordial nuclides are radioactive elements whose half-lives are comparable to the age of our solar system and were present at the formation of Earth.Nuclear chemistry is the study of the chemical and physical properties of elements as influenced by changes in the structure of the atomic nucleus.Modern nuclear chemistry, sometimes referred to as radiochemistry, has become very interdisciplinary in its applications, ranging from the study of the formation of the elements in the universe to the design of radioactive drugs for diagnostic medicine.

Nuclear chemists were involved in the chemical purification of plutonium obtained from uranium targets that had been irradiated in reactors.

  1. Ironically enough, if you could take the best of those women and the best of those men, and place them in a big room where they could sit at a table and ask each other questions in person – you’d probably have 4 or 5 new match-ups by the end of the night.
