RESEARCH TASK AND WRITTEN REPORT
Many theoretical and experimental problems were not solved in the early twentieth century. There were attempts to explain the behaviour of matter on the atomic level with the laws of classical physics however they were not accurate nor successful. It was not until the period between 1900 and 1930 where a revolution occurred and a generalised formulation called quantum mechanic was developed. And since the understanding of the structure of the nucleus of the atoms led to the development of different technologies and applications. The way how our understanding has grown will be discussed in the follow report.
THE WORK OF JAME CHADWICK AND ENRICO FERMI
James Chadwick:
• In 1930’s – Bothe and Becker, two scientists …show more content…
One called Little Boy and the other called Fat Man.
Little Boy was the first Uranium detonation bomb ever created. It was a collision and fusion of two sub critical masses of Uranium 235 by conventional external explosions into one critical mass.
Fat Man was a plutonium implosion nuclear weapon consisting of plutonium 239, Beryllium and Polonium as the core. It was a less fissionable substance than Uranium 235. Beryllium with Polonium is less critical so it maintains the Plutonium 239 to the side. But when Plutonium 239 pushes towards the centre, it then causes the elements to explode.
The significance of these two bombs were that they were the first of its kind to be constructed. New engineering techniques were invented to construct the bomb. After the project, scientists became more interested with radioactive elements. As a result, they began experimenting with these elements for medical uses, engineering uses and agricultural uses.

It works by directing beams of radiation at the object that is being checked. Example water pipes running beneath the house underground. If there is a defect in the object being tested, the film from the radiography will be darker as that is a sign to where the crack is because more radiation is able to pass through it. Cobalt-60 is used in engineering because the gamma radiation that it emits is able to penetrate metal parts. It has a half life of 5.2 years which can be used in a chemically inert form that allows the equipment to have a longer lifetime and not requiring regular
