  1. GEOL 108 - Crises of a PlanetLab 10 - Toxic Waste • Nov. 6 - 9, 2012 Department of Earth Sciences

  2. QUIZ 8 REVIEW What are the two types of stream morphologies? (1 pt) Sketch both (2 pts) and show where cut banks and point bars occur (1 pt), indicating which is caused by erosion and which by deposition. REVIEW | 2 Department of Earth Sciences

  3. LAB 10- TOXIC WASTE + = Robocop (1987) TOXIC WASTE | 3 Department of Earth Sciences

  4. RADIOACTIVE DECAY • Pu-239 is a common waste product of nuclear fission. • Decay of Pu-239 produces an alpha particle (He atom) which is not a serious threat until ingested. • Alpha particles cause extreme chromosomal damage to cells and lead to cancer • TOXIC WASTE | 4 Department of Earth Sciences

  5. RADIOACTIVE DECAY • TOXIC WASTE | 5 Department of Earth Sciences

  6. NUCLEAR ENERGY • Nuclear energy as % of total energy production by country http://intuitech.biz/nuclear-energy-technology-roadmap/ • TOXIC WASTE | 6 Department of Earth Sciences

  7. NUCLEAR ENERGY • Location of operating nuclear power plants • TOXIC WASTE | 7 Department of Earth Sciences

  8. NUCLEAR ENERGY Robert A. Rohde • TOXIC WASTE | 8 Department of Earth Sciences

  9. RADIOACTIVE WASTE • Hanford, Washington • 53 million gallons of high-level radioactive waste on site after facility closed • TOXIC WASTE | 9 Department of Earth Sciences

  10. RADIOACTIVE WASTE • Yucca Mountain • TOXIC WASTE | 10 Department of Earth Sciences

  11. RADIOACTIVE WASTE • Faults and groundwater at Yucca Mountain Radioactive Man and Fallout Boy • TOXIC WASTE | 11 Department of Earth Sciences

  12. USES OF RADIOACTIVE DECAY • Absolute ages by radiometric dating • Example: Certain minerals, like zircon, take in uranium but not lead while growing • U235/Pb207 system half-life: 713 million years • TOXIC WASTE | 12 Department of Earth Sciences
