It all started with the discovery of uranium. According to the World Nuclear Association, “Uranium was discovered in 1789 by Martin Klaproth, a German chemist, and named after the planet Uranus.” This discovery alone led to the use in the medical field, Radium was later used in medical treatment. Then in 1898 where Samuel Prescott discovered that radiation could be used to destroy bacteria in food.1 It also led to the discovery and research of the atom and the many elements. This was important because this discovery showed how nuclear energy could be used as the basis for making the atomic bomb. In 1902 Ernest Rutherford showed that the alpha and beta particles being released from the nucleus created a different element.1 With our further understanding of the atom came the discovery of the electron configuration of the atom, which was studied and advanced in the 1940’s by Niels Bohr.1 But this discovery also led to the discovery that uranium could be manipulated to become a new source of energy which would then be developed as the first nuclear bomb. According to the World Nuclear Association, “they calculated the energy release from this fission as about 200 million electron volts. Frisch then confirmed this figure experimentally in January 1939.”1 This showed the glimpse of the destruction that would soon kill millions. With this new found data help develop a spark in laboratory activity in 1939. According to the World Nuclear Association, “Hahn and Strassmann showed that fission not only released a lot of energy but that it also released additional neutrons which could cause fission in other uranium nuclei and possibly a self-sustaining chain reaction leading to an enormous release of energy.”1 With this we were one step closer to the atomic bomb. According to the World Nuclear Association, "Ohr and Wheeler extended these ideas into what became the classical analysis of the fission process, and their paper was published only two days before war broke out in 1939.”1 What this shows is the catalyst that sped up the want of this weapon of mass destruction. According to the World Nuclear Association, “the remaining piece of the fission/atomic bomb concept was provided in 1939 by Francis Perrin who introduced the concept of the critical mass of uranium required to produce a self-sustaining release of energy. This was important because by manipulating nuclear energy in this matter the atomic bomb could be created. His theories were extended by Rudolf Peierls at Birmingham University and the resulting calculations were of considerable importance in the development of the atomic bomb.”1 around this time World War II had just started and the discussion of the use of nuclear power in military use was in development. At this time the devastating use of what we now know as the atomic bomb was still just an idea at this time, so many people we on board for further research. The US detonates a uranium bomb over the Japanese city of Hiroshima, killing more than 140,000 people within months. Many later died from radiation-related illnesses. But many did not comprehend what they had in their possession could spell out so much destruction.radiation-related illnesses.
