The resulting radiation showed high penetration through a lead shield, which could not be explained via the particles known at that time. WebHe is most well-known for his discovery of the neutron, which he announced in 1932. This discovery helped to explain the structure of the atomic nucleus and played a crucial role in the development of nuclear energy. In 1935, Chadwick was awarded the Nobel Prize in Physics for his discovery of the neutron. classification of climate change
