PPT-Gamma rays, Fission ~bombs and nuclear power

Gamma radiation In gamma radiation no particle is released just a packet of energy Photon packet of energy When an atom has too much energy it is excited its electrons are in higher energy levels. Special Topic 2014. Exam Craft mock 2014. Define the term Nuclear Fusion:. It is the process the nucleus of an atom (uranium or plutonium) is bombarded with neutrons. This splits the nucleus (fission) realising large amounts of energy in the form of heat.. The Nucleus. Protons – . 1.672 . × 10. 27. kg. Neutrons – 1.675 . × 10. 27. kg. isotopes. Strong Nuclear Force. Holds the protons and neutrons together.. Third Fundamental Force (after gravity and the electromagnetic forces). . Stations. . Nuclear power station. s. Introduction. . What’s in a Nucleus. The nucleus of an atom is made up of . protons. and neutrons. each is about 2000 times the mass of the electron, and thus constitutes the vast majority of the mass of a neutral atom (equal number of protons and electrons). Radiation for life. Sparks. Insulating materials. Metals are . good conductors. , which means that electric charges move easily through them. Materials such as plastic, wood, glass and polythene are . at NPL. Paddy Regan. NPL . Radioactivity Group, AIR Division. & . Department of Physics, . University . of Surrey. Nuclear Data?. ‘Nuclear Data’ and its evaluation underpin many areas of both applied and fundamental nuclear science, including. Nuclear power plant. 2. NUCLEAR FUEL. Nuclear . fuel is any material that can be consumed to derive nuclear energy. The most common type of nuclear fuel is fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear reactor . ~bombs and nuclear power. Nuclear fission. ~the separating of a nucleus of an atom.. This is the process used by nuclear power stations (when it is kept under control).. It is also the process of an atom bomb (when it is allowed to run uncontrolled). . http://science.howstuffworks.com/nuclear-power1.htm. 10 facts about NUCLEAR FISSION. 1. . Nuclear Fission is the splitting of an atomic nucleus into two smaller nuclei of approximately equal mass. . Nuclear Fission. We convert mass into energy by breaking large atoms (usually Uranium) into smaller atoms. Note the increases in binding energy per nucleon.. A slow moving neutron induces fission in Uranium 235. Giant Shocks in the Fermi Bubbles and the Origin of the Microwave Haze. Roland Crocker. ARC Future Fellow. Australian National University. image credit: NASA. Geoff Bicknell, RSAA. Ettore Carretti, Cagliari Observatory. 12/11/20. | . 1. Gamma-rays are ideal probes of a subset of the radioactive isotopes produced in astrophysical transients.. A number of new gamma-ray missions are being developed (ASCENT, COSI, LOX, AMEGO, …) that will improve sensitivities by over an order of magnitude, allowing us to probe more transients and a broader range of isotopes*.. Enormous Energies. Nuclear Fission. Take a large atom and impact the nucleus with a particle. . Split the atom releasing high energy, more high energy neutrons, and two daughter nuclides.. Fission occurs only rarely in nature. Alpha decay is much more common.. 8.4.2 Distinguish between controlled nuclear and uncontrolled nuclear fission. . 8.4.3 Describe what is meant by fuel enrichment.. Topic 8: Energy, power, climate change. 8.4 Non-fossil fuel power production. Atom structure. 1. 2. 3. What is the radius of an atom?. What is the radius of a nucleus?. 1x10. -10. m. 1x10. -15. m. Atom structure. An isotope is an element with a different number of neutrons. Isotope.
