FRONTLINE: nuclear reaction: karen silkwood Karen Silkwood died on November 13, 1974 in a fatal one-car crash. Since then, her story has achieved worldwide fame as the subject of many books, magazine and newspaper articles, and even a major motion picture. Silkwood was a chemical technician at the Kerr-McGee's plutonium fuels production plant in Crescent, Oklahoma, and a member of the Oil, Chemical, and Atomic Workers' Union. After her death, organs from Silkwood's body were analyzed as part of the Los Alamos Tissue Analysis Program at the request of the Atomic Energy Commission (AEC) and the Oklahoma City Medical Examiner. In the evening of November 5, plutonium-239 was found on Karen Silkwood's hands. The two gloves in the glovebox Silkwood had been using were replaced. Silkwood arrived at work at 7:30 A.M. on November 6. On November 7, Silkwood reported to the Health Physics Office at about 7:50 in the morning with her bioassay kit containing four urine samples and one fecal sample. The next day, Dr.
Nuclear Energy is the most certain future source. by John McCarthy This page discusses nuclear energy as a part of a more general discussion of and should be sustained. is just one of the questions considered. Up to: Main page on why progress is sustainable Incidentally, I'm Professor of Computer Science at Stanford University, emeritus (means retired) as of 2001 January 1. Here's a new page on . One of the major requirements for sustaining human progress is an adequate source of energy. Q. A. Nuclear power can come from the fission of uranium, plutonium or thorium or the fusion of hydrogen into helium. Natural uranium is almost entirely a mixture of two isotopes, U-235 and U-238. Most nuclear power plants today use enriched uranium in which the concentration of U-235 is increased from 0.7 percent U-235 to (nowadays) about 4 to 5 percent U-235. In 1993 there were 109 licensed power reactors in the U.S. and about 400 in the world. For how long will nuclear power be available? Cohen's argument is based on using uranium from sea water.
Lesson Plans - Low-level Nuclear Waste: A Geographic Analysis Grades 9 - 12 Overview: In this lesson, students will learn how to analyze the problems surrounding nuclear waste . They will compare and contrast low- and high-level nuclear waste, and make decisions concerning how to dispose of low-level nuclear waste. Connections to the Curriculum: Geography, current events, environmental science, history Connections to the National Geography Standards: Standard 18: "How to apply geography to interpret the present and plan for the future" Time: Two to three hours Materials Required: Objectives: Students will learn what radioactive waste is; learn the impacts that a nuclear waste depository could have on a geographical region; explore how their local community manages low-level nuclear waste (if applicable); examine the decisions that go into choosing a region for a nuclear waste repository; and think about the future implications of storing nuclear waste. Geographic Skills: Asking Geographic Questions Acquiring Geographic Information Organizing Geographic Information
FRONTLINE: nuclear reaction: related links This selection of Web sites has been organized into: anti-nuclear power ; pro-nuclear power ; government agencies ; ' fun and interaction ;' FAQ sites ; Chernobyl ; Inside a Nuclear Plant ; and issues . Animation on the first page morphs a nuclear power plant into a mushroom cloud. The NCI is an anti-proliferation group formed by scholars. Even if the fear of nuclear proliferation doesn't entertain you, this award-winning site will. Its newest feature is a point-by-point rebuttal of FRONTLINE's report on Americans' fear of nuclear energy. Here is a chronicle of the nuclear age. This group put up this straight-talking site that dispels a lot of myths about nuclear power and tries to set the record straight. Another site you can feel good about reading (because it's not too heavy on propaganda) is one by the non-profit World Nuclear Association. The authors of this report include the World Health Organization and the UN. Greenpeace's Stop Plutonium page is colorful and easy to read.
The Why Files | 1. Radiation, 60 years later In 2005, 60 years after the atomic bomb was invented, the specter of ionizing radiation again lurks behind the news: : How deadly would the released radiation be? : Can it operate safely? The Department of Energy must jump enormous technical hurdles before opening this repository for nuclear waste in Nevada. Are the radiation exposure standards strict enough? Too strict? : Safe response to global warming and energy shortages? : Can they cause cancer? : Useful medical tools that detect disease with X-rays, or a dangerous source of extra radiation exposure? CT scans are a valuable medical tool, but they increase our exposure to ionizing radiation. The answer to these questions hinges on the health effects of low-level radiation. First, some definitions: Ionizing radiation -- alpha and beta particles, and X-rays and gamma rays -- is released by nuclear reactions in bombs, power plants and uranium-bearing rocks (X-rays are also made in medical equipment).

A Surprising Result Decade of Discovery Thomson's Atom Bibliography Acknowledgements More particle physics pages The ladies and gentlemen could not believe what they were hearing. The date was Friday, April 30, 1897. By the desk in the center of the theater stood a man with a pince-nez, a straggling mustache, and a receding hairline. Earlier that year, Thomson told his audience, he had made a surprising discovery. No wonder the audience thought Thomson was joking. Thomson himself didn't want to believe in these new particles. Thomson called his particles corpuscles, meaning "small bodies." Electrons are elementary particles, which means that, as far as we can tell, they are not made of anything smaller. It was by chance that Thomson became a professor of physics. Thomson studied engineering, but found he was more interested in mathematics. On his second attempt, Thomson won the scholarship.
