** Atom and Introduction to Nuclear physics ** Introduction Alpha-particle scattering 2.1 Experimental set-up ➢ Alpha particle o is a high-energy helium nucleus with 2 protons and 2 neutrons. o has 2 positive charges. ➢ Gold foil was chosen since it has a high atomic mass. Thin gold foil‚ ~10-6m was bombarded by high-energy alpha particles. ➢ Angular deflections/ scattering of alpha particles were measured by observing

Nuclear Reactors An Overview Nuclear reactor is any class of devices that can initiate and control a self-sustaining series of nuclear fissions. Nuclear reactors are used as research tools‚ as systems for producing radioactive isotopes‚ and most prominently as energy sources for nuclear power plants.Djeresssi (1991) Principles of operation Nuclear reactors operate on the principle of nuclear fission‚ the process in which a heavy atomic nucleus splits into two smaller fragments. The nuclear fragments

We all know that energy on earth is running out‚ but what if we could use stars? Stars contain so much energy‚ if we could harvest it‚ we would never run out of energy. Energy from stars could be the energy source we are looking for. Energy is something we probably take for granted‚ we use so much of it everyday‚ and our current energy source‚ fossil fuels‚ releases gases into the environment‚ but with energy from stars‚ it could be a fresh start for our energy sources and our environment. Stars

NUCLEAR REACTORS A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas)‚ which runs through turbines. These either drive a ship’s propellers or turn electrical generators. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are

The beginning of the nuclear war will be the end of mankind Nuclear war will lead to Human extinction The atomic bombs dropped on Hiroshima and Nagasaki at the end of the second world war wiped out the entire place leaving it without any form of existence. This incident changed the history of war completely. For miles and miles the atmosphere was polluted and people had faced the radioactive rays. These rays proved to be very harmful to the upcoming generations. Children were born with all

Nuclear power‚ or nuclear energy‚ is the use of exothermic nuclear processes carried out in controlled manner‚ to generate useful heat and electricity. Nuclear power works by using the energy from nuclear fission or fusion to generate heat. At the moment‚ nuclear fusion is still a subject of intense research and not used in production which is a pity. Nuclear fission is basically what is happening in a reactor. Radioactive elements have unstable nuclei and they are constantly going through random

Research Paper Social Issues in Constant Discussion Daniel A. R. January 16‚ 2013 Nuclear Proliferation [1] The birth of the Atomic Era was one of the most undesirable events in history of mankind since it was time in which countries focused investigation on fissionable material to use as weapons of mass destruction. However‚ even if it was seen as an undesirable event mostly by common civilians‚ it was also‚ on the other hand‚ seen as an era of development of modern warfare for governments

“Nuclear Technology is the leading international publication reporting on new information in all areas of the practical application of nuclear science.” (American Nuclear Society) Today‚ nuclear technology is used for a variety of reasons that include weapons‚ medicine‚ food and agriculture‚ smoke detectors‚ and environmental protection. However‚ many people see nuclear technology as a destruction that could eventually kill us all. In addition‚ people believe that if scientists keep developing and

Nuclear Proliferation INTRODUCTION: In the world today‚ there are many controversies that affect our every day lives‚ and these are important to stay informed about to be informed about. In this paper‚ I will review the history and up rise of nuclear weapons‚ and how nuclear proliferation has become a fear for the world. I will describe in detail what treaties‚ NGO & IGOs are involved with the topic‚ and the nations involved with nuclear proliferation. The more we know about the history and
