PUBH 3132 Lecture Notes - Lecture 5: Iodine-131, Kyoto Protocol, Yellowcake
Document Summary
Burning of fossil fuels puts sequestered carbon back into circulation as co2. Co2 is single most influential greenhouse gas. Lesser greenhouse gases: methane, ozone, halocarbons, nitrous oxide. Increased temperature of ocean water: thermal expansion of water: rise on sea level. Extreme weather events: crop failures, famine, infectious disease. International agreement to reduce emissions of greenhouse gases. Industrialized nations agreed to reduce collective emissions to level 5. 2% below. Regulation of air pollution from burning of fossil fuels. Regulation of mobile sources of air pollution. Increases proportion u-235 by removing u-238 from yellow cake. Require only hundreds of years to be comparable to background radiation. New organization has responsibility for management of nuclear wastes. Work begin promptly to prepare for transport of spent fuel and high level. Health impacts of nuclear fuel cycle wastes. Radiation exposures and health effects of the nuclear fuel cycle. Dose related increase in thyroid cancer in children and adolescents. Evidence of increase in leukemia among cleanup workers.
