Fundamentals of Nuclear Chemistry

Title	Alpha decay
Caption	The diagram shows alpha decay and illustrates the nuclear changes that accompany the emission of an alpha particle.
Keywords	alpha, decay, plutonium, uranium, nuclei, emission, mass number, atomic number, transmutaion, radiation

18-01-01UN

Title	Beta decay
Caption	The diagram shows that a neutron is transformed into a proton as it ejects a beta particle (an electron) during beta decay.
Keywords	beta, decay, electron, emission, nuclei, mass number, atomic number, transmutation, radiation

18-02

Title	Beta decay of carbon-14
Caption	The diagram shows beta decay and illustrates the nuclear changes that accompany the emission of a beta particle.
Keywords	beta, decay, electron, emission, nuclei, mass number, atomic number, carbon, nitrogen, radiation

18-04

Title	Penetrating power of radiation
Caption	The diagram illustrates the penetrating power of alpha, beta, and gamma radiation through paper, aluminum, and lead. The extent to which a material is penetrated by radiation depends on both the kind of radiation and the kind of material being bombarded.
Keywords	alpha, beta, gamma, penetrating power, radiation. density

18-05

Title	Penetrating power analogy
Caption	Shooting radioactive particles through matter is like rolling rocks through a field of boulders - the larger rocks are more quickly stopped.
Keywords	alpha, beta, gamma, penetrating power, analogy, boulders, radiation

18-06

Title	Radioactive decay of tritium
Caption	The graph shows the effect of radioavtive decay on the number of tritium atoms remaining as a function of time, beginning with an initial sample of 16 billion atoms.
Keywords	tritium, half-life, beta, decay, radioactive, isotope, radiation, radioisotope

18-09

Title	Uranium-238 decay series
Caption	The chart shows the uranium-238 decay series. Each alpha particle emission reduces the mass number of an atom by 4 and the atomic number by 2. The emission of a beta particle raises the atomic number of an atom by 1 but does not change the mass number.
Keywords	decay, series, uranium-238, lead-206, alpha, beta, atomic number, mass number, raioactive, isotope

18-10

Title	Pi chart showing radiation exposure
Caption	Most of our exposure to radiation comes from natural sources (82%). The largest single contribution is from radon (55%)
Keywords	radiation, exposure, radiation, background, damage, potassium-40, chart, radon, radioactive

18-12

Title	Positron emission
Caption	The diagram illustrates the nuclear change accompanying positron emission.
Keywords	positron, electron, emission, nuclei, mass number, atomic number, transmutation, radiation, nuclear

18-19

Title	Splitting of a uranium atom
Caption	The diagram illustrates the splitting of a uranium atom. The neutrons produced in this fission can split other uranium atoms, thus sustaining a chain reaction. The splitting of one uranium-235 atom yields 8.9 x 10-15 kWh of energy. Fission of a mole of uranium-235 produces 5,300,000 kWH of energy.
Keywords	nuclear, fission, splitting, uranium, neutron, chain reaction, energy

18-20

Title	Nuclear chain reaction
Caption	Schematic representation of a nuclear chain reaction. Neutrons released in the fission of one uranium-235 nucleus can strike another nucleus, causing it to split and release more fragments. For simplicity, fission fragments are not shown.
Keywords	nuclear, fission, splitting, uranium, neutron, chain reaction, energy

18-22

Title	Nuclear power plant
Caption	Schematic diagram of a nuclear power plant used to generate electricity.
Keywords	nuclear power, light water, reactor, turbine, steam generator, heat exchanger, electricity, fission, cahin reaction
