FOREWORD After the use or application of radioactive materials or the utilization of nuclear energy, some radioactive residues may remain in the environment and give rise to the exposure of persons living or working in that environment. Most commonly, these residues are the result of human activities that have been carried out in the past without proper regard to the internationally accepted radiation protection requirements for practices, or at a time when those requirements were less stringent than today. Of course unforeseen events such as accidents or concentrations of naturally occurring radioactive material can also lead to higher levels of radioactive residues in the environment. The purpose of this Symposium is to foster an information exchange on the restoration of environments with radioactive residues. This includes the principles and criteria for guiding decision making and the methodologies for assessing the radiological situation and developing remediation plans for the human habitats affected. The overall aim is to promote an international consensus on the relevant issues in these areas.

Tallium, Estonia Abstract Quick launch of the nuclear program was a high priority for the Soviet military, as a uranium production plant installation was started at Sillamae, Estonia, in 1946. Estonian local ore - alum shale - containing only 0.03 % of uranium was used for uranium production for nearly five years, after the plant was launched in 1948. Altogether more than 4 million tons of ore, imported mostly from Central and East European countries (Czechoslovakia, Hungary and Eastern Germany) were processed at Sillamae. These activities have left a large tailings

  • The Nuclear Boy Scou1
    THE NUCLEAR BOY SCOUT In 1994 David Hahn, a 17-year-old from Detroit, Michigan, learned that it was possible to find small amounts of radioactive material in common store- bought items. Americium-241, for example, is found in most smoke detectors. The science-minded Boy Scout set his sights on earning the (now-discontinued) "Atomic Energy Badge"...by building a nuclear reactor in his mother's backyard shed. First, he had to create a "neutron gun" (the nuclear reactions that power most nuclear plants are set off by bombarding a radioactive element, usually uranium, with neutrons). Hahn collected Americium-241 from hundreds of smoke detectors and packed them into a hollow piece of lead with a tiny opening. Radiation can't pass through lead, so the radiation from the americium-241 could now only escape through that pinhole—as a focused beam. Hahn covered the hole with a thin strip of aluminum, which reacts to radiation by ejecting neutrons. He now had his "neutron gun." Hahn’s accelerator Over the next several months, Hahn attempted to create a nuclear reaction by shooting different radioactive substances with his neutron gun. That included thorium-232, which can be found in gas camping lanterns, and beryllium, which he stole from a chemistry lab. After that, he acquired some pitchblende, a type of rock that contains small amounts of uranium. Hahn never succeeded in creating a nuclear reaction...but he did create extremely dangerous levels of radiation—more than 1000 times normal levels. The fiasco finally ended when police stopped Hahn one night in August 1994, and he told them he had radioactive substances in his car.

  • The Nuke Kid on the Block
    NUKE KID ON THE BLOCK David Hahn was an ordinary American teenager who went to extraordinary lengths to obtain his boy scout badge – he built a nuclear reactor in his back yard. By Ken Silverstein There is hardly a boy or a girl alive who is not keenly interested in finding out about things. And that’s exactly what chemistry is: FINDING OUTABOUT THINGS—finding out what things are made of and what changes they undergo. What things? Every thing! (The Golden Book of Chemistry Experiments) Golf Manor is the kind of place where nothing unusual is supposed to happen, the kind of place where people five precisely because it is more than 25 miles outside Detroit and all the complications attendant on that city. The kind of place where money buys a bit more land, perhaps a second bathroom, and so reassures residents that they're safely in the bosom of the middle class. Every element of Golf Manor invokes one form of security or another, beginning with the name of the suburb itself - taken from the 18-hole course at its entrance — and the community in which it is nestled, Commerce Township. The houses and trees are both old and varied enough to make Golf Manor neighborhood than a suburb, and the few features that do convey suburbia- a sign at the entrance saying, “We have many children but none to spare. Please drive carefully" — have a certain Back to the Future charm. Most Golf Manor residents remain there until they die, and then they are replaced by young couples with kids.

  • 16. Contrasting Dual-Use Issues in Biology and Nuclear Science
    16. Contrasting Dual-Use Issues in Biology and Nuclear Science Nicholas G . Evans Dual use and nuclear science The so-called ‘dual-use dilemma’—which arises when scientific research, materials or technologies can be used to both benefit and harm humanity1—is not an altogether new phenomenon. Early in the twentieth century, nuclear science—here, the study of the properties of atomic nuclei—raised similar concerns about materials, technologies and knowledge that had the potential to be used to benefit humanity, but also posed serious risks of misuse. Comparing the experiences of the nuclear sciences with those of biology in regulating dual- use materials, knowledge and technology will be the focus of this chapter. Nuclear science raises a number of dual-use issues. Nuclear science has many beneficial uses, the best known being nuclear-fission (the process by which a nucleus is split into two or more smaller parts) reactors. These reactors are useful in power generation, and are also used to create radioisotopes—elements that are subject to radioactive decay that have a variety of uses described below. Nuclear fusion (the process of ‘fusing’ two lighter nuclei into a heavier nucleus) is currently being explored as a cleaner, more plentiful fuel source that could become an important source of energy in years to come. Non-fissile radionuclides—radioactive substances not capable of energetic fission—have a range of useful and beneficial medical, agricultural, construction, military and aviation applications, to name a few. Radioisotopes have therapeutic applications in medicine, as their emissions can be used to bombard and kill cancerous cells with radiation.

Elkins1* 1Chemistry Department, Towson University, 8000 York Road, Towson, MD 21252, *corresponding author: [email protected] Abstract: Nuclear forensics is the investigation and analysis of the source of nuclear materials for nuclear attribution including trafficking and illegal possession and enrichment of natural materials. Nuclear forensics cases include radionuclide theft, illegal trafficking and possession, loss of nuclear weapons, and poisonings. To prepare forensic chemists to handle materials in these cases and law enforcement to thwart these threats, nuclear forensics courses are offered at United States colleges and universities. This paper reports upon the field of nuclear forensics including history and cases, ongoing threats that underscore the need for education, courses offered and topics covered, internship and training opportunities, and expert witness testimony in nuclear forensics. A robust reference list of peer-reviews papers, websites, books and book chapters that can be used in such a course is included.

  • Teenage Experiments Contaminate Suburban Property
    TEENAGE EXPERIMENTS CONTAMINATE SUBURBAN PROPERTY P.LALL U. S. Environmental Protection Agency, Emergency Response Branch, Grosse He, Michigan, United States of America L. JENSEN, J. MITCHELL XA9953174 U.S. Environmental Protection Agency, Superfund Division, Chicago, Illinois, United States of America W. SASS Ecology & Environment; Chicago, Illinois, United States of America R. SKOWRONEK, D. MINNAAR Michigan Department of Public Health. Lansing, Michigan, United States of America Abstract In August 1994, 18-year-old David Hahn (David) was detained by police in Clinton Township, Michigan. When the police searched his car, they discovered a locked tool box and other containers that David said contained radioactive materials resulting from experiments he had conducted with the radioactive materials from, primarily, consumer products. From the ages 14 to 18, David spent his spare time at his Union Lake, Michigan, home attempting to concentrate, burn, chemically alter, and experiment with: the thorium from hundreds of lantern mantles, radium from various luminescent sources and clock dials, americium from smoke detector sources, and radioactive materials from natural ores. In the process, he had contaminated a wooden shed in his backyard and his bedroom, and exposed himself. In 1995, EPA, their emergency response contractor, and the Michigan Department of Public Health (MDPH) performed an emergency assessment and removal at the property. The response and removal were conducted cost-effectively and generated approximately 10 cubic yards of radioactive waste. Introduction On August 30, 1994, 18-year-old David, who resided at the home of his father and stepmother in Clinton Township, Michigan, was detained by Clinton Township police. While searching the car, police discovered material stored in a locked, aluminum foil-covered tool box that David reported to be radioactive.

    WHEN TERRORISTS FIGHT DIRTY : THE LIKELY MAGNITUDE OF A TERRORIST RADIOLOGICAL ATTACK IN THE UNITED STATES A Thesis submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Master of Arts in Security Studies By Jessica Satterfield, A.B.J. Washington, DC April 6, 2011 Copyright 2011 by Jessica Satterfield All Rights Reserved ii WHEN TERRORISTS FIGHT DIRTY : THE LIKELY MAGNITUDE OF A TERRORIST RADIOLOGICAL ATTACK IN THE UNITED STATES Jessica Satterfield, A.B.J. Thesis Advisor: Genevieve A. Lester , M.A. ABSTRACT This study examines the threat of a radiological dispersal device (RDD) attack against a major US city, and explores the various methods for measuring the scale of the threat to determine which best applies to a real world scenario. First, the research will examine past terrorist and lone actors’ attempts to construct an RDD, compared to an overview of the types and amounts of radioactive material currently missing in the United States. An analysis of these two datasets will allow for a determination on the most likely type and scale of RDD attack that could be carried out in the United States using currently available materials. This type and scale of attack will then be compared to existing methods of RDD measurability, and will propose additional sub-categories to these scales to more effectively address the most likely real-world scenario. iii The research and writing of this thesis is dedicated to my mother and teacher, Dianne Jackson Satterfield. Thank you for teaching me all I know.
