** 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

Nuclear waste is dangerous just about anyone knows that. But is it really that dangerous or is it simply overstated? The answer to this question is a heated debate that involves everybody from politicians pushing for policy they don’t really understand to scientists who are trying to understand it to the public who take everything they hear as the truth. Honestly‚ I don’t even know if I can iron out the edges of this frenzied debate. Everyone‚ and that includes me‚ has their own perspective of the

It’s like I should be ready and prepared to die if necessary from an attack. I would constantly be looking over my shoulders and worrying

Nuclear Weapons Definition: A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions‚ either fission or a combination of fission and fusion. Types: There are two basic types of nuclear weapons: those that derive the majority of their energy from nuclear fission reactions alone‚ and those that use fission reactions to begin nuclear fusion reactions that produce a large amount of the total energy output. History: Starting with scientific breakthroughs made

world without nuclear weapons would be less stable and more dangerous for all of us.” In the article “Get real: nuclear power is in your future” Allan Kupcis argues that nuclear power is a necessity to maintain “the backbone of any economy.” Thus‚ in our day to days living‚ we seem to ask ourselves about what is meant by the term "Nuclear Energy." Some will give the right concept of the nuclear energy but others will not. It all depends with the knowledge one has about the nuclear energy. In this

Nuclear weapons were first developed by the United States prior to the start of World War ll. The first and only times that nuclear weapons were used in battle was against Japan in 1945. The United States dropped two different style of nuclear weapons on two different Japanese cities. One bomb used plutonium while the other used uranium to create the explosions. The bombs were dropped on Hiroshima on August 6‚ 1945 and Nagasaki on August 9‚ 1945. Estimates of deaths within the four months after
