Radiation is all around us but the human body has no natural way to detect it, so we have only really known about its existence since the last decade of the 19th century and the work started by Wilhelm Röntgen on X-rays and Henri Becquerel on radiation from uranium. Other pioneers such as Marie and Pierre Curie and Ernest Rutherford helped us further understand the nature of the nucleus and radiation.

Following the discovery of the neutron in 1932 by James Chadwick experiments were carried out by aiming beams of neutrons onto various elements. When Otto Hahn and Fritz Strassmann tried this with uranium, lighter elements were observed. Incorporating theoretical calculations by Lise Meitner and Otto Frisch this was the discovery of induced nuclear fission. Since the early reactors at Calder Hall, UK, Obninsk, Russia and Shippingport, USA in the 1950s nuclear fission has been used to produce electricity.

This site has been established to explain radiation and nuclear energy.
