Cesium-137 Fallout in Indiana Soil E Page a Dissertation CESIUM-137 FALLOUT IN INDIANA SOIL E PAGE A DISSERTATION SUBMITTED TO THE GRADUATE SCHOOL IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREEE DOCTOR OF EDUCATION IN SCIENCE BY RICHARD T. WHITMAN DISSERTATION ADVISOR: DR. JOHN PICHTEL BALL STATE UNIVERSITY MUNCIE, INDIANA DECEMBER 2017 ABSTRACT DISSERTATION: CESIUM-137 FALLOUT IN INDIANA SOIL STUDENT: Richard T. Whitman DEGREE: Doctor of Education in Science COLLEGE: Sciences and Humanities DATE: December 2017 PAGES: 129 Atomic weapons testing during the Cold War and accidents at nuclear power plants have resulted in the release of radioactive fallout over great distances. Little is known about levels of fallout deposited in Indiana. The reported study sampled soil in all 92 Indiana counties to determine the present level of cesium-137 from the 2 to 12 centimeter depth from previous nuclear tests and other nuclear releases. A total of 67 samples were collected from forested areas and 25 from grasslands, both undisturbed since 1940, along with four controls from crawl spaces. Greater Cs- 137 retention occurred in the forested areas at approximately a 2:1 ratio. Other parameters investigated included soil clay content, rate of rainfall, and soil pH. Each variable was examined for possible statistical correlation with Cs-137 retention. Both clay content and combined clay content/rainfall were significantly (p < 0.05) correlated with soil Cs-137 levels. The four controls showed very low values of Cs-137 indicating the movement of sub-micron sized fallout into areas considered safe from fallout. The Cs-137 data from this study will serve as a reliable baseline of Cs-137 levels in the event of a future release of fallout. Keywords: Indiana; cesium-137; fallout ii DEDICATION This dissertation is dedicated to Sophie Abbott. iii ACKNOWLEDGEMENTS Many people influenced my thinking and desire to pursue this research. First among these: Dr. Rick Venedam and Asa Von Sudderth who worked for the Nevada Test during my active duty recall with the Defense Threat Reduction Agency. A second group at Indiana University Purdue University Indianapolis, Dr. (COL-Ret.) William A. Foley Jr, (COL-Ret.) Jim White, Dr. Abdul Sadeek, Denise Scroggins and Curtis Ramsey, at the School of Professional and Environmental Affairs; Dr. Vijay Lulla, Dr. Rick Bein, and Dr. Phil Roth of Geography; Dr. Gabriel Filippelli and Dr. William Gilhooly of Earth Sciences helped shape this work. In 2015, I transferred my studies to Ball State University where the faculty of the Natural Resources and Environmental Management (NREM) program provided further support. From the start, Dr. John Pichtel (Advisor) and the Dissertation Committee for this work: Dr. Amy L. Gregg, Dr. Joshua B. Gruver, and Dr. Jessique Ghezzi; and Dr. Petra Zimmermann (Geography) all provided encouragement. Dr. Jose Ramirez-Dorronsoro and Stan Ross of NREM and Dr. Roger Wessel and Dr. Serena Salloum of the Education Department, all guided my research methods. The long term friendship of (COL-Ret.) Dave Murphy, JD also made a difference. Colleagues from my government working career need mention: Dr. Gordon Riel, James Stafford, Jim Meyers from the Naval Surface Warfare Center. Steve Tilden, Joe Thompson, Tim Kelly, David Walls, Audra M. Upchurch, Roy Lindquist, Richard Schueller, Jim Winso, Linda Bray, Mike Gray, Ken Fagan, Stacy Wright, Brian Hrynyshen all supported DHS and made a difference following the 9/11/2001 response to terrorism. Bob Michaud and many uniformed CBP Officers helped in the development of training that reached 16,800 Officers. Mr. Art Morgan, and many others at FLETC always accommodated and supported new training ideas. Among those with special scientific insight, Dr. (COL-Ret) . Glen Reeves, MD, Dr. iv (CAPT-Ret.) Paul Blake (of DTRA) and especially CAPT John Cardarelli (US Public Health Service), John D. Kinneman and Dr. Satar Lodhi (of the U.S. Nuclear Regulatory Commission) provided technical comment going back nearly three decades along with William I. King, P.E., Paul P. Psomas and Stephen Malone. Inspiration came from members of several ANSI Committees, including Dave Hamel of (OSHA), Dr. Larry Hudson and Dr. Paul Bergstom (NIST), and Daniel Kassiday (FDA). Sean and Kelly Austin and Dr. Alan Fellman, always enjoyed training questions especially Eli Port and Aaron Morris at RSSI, Inc, Dr. Jim Schweitzer and his Radiation Safety Staff, especially Matthew Tang, at Purdue University showed the advantage of ORTEC systems. The Hoosier Health Physics Chapter has always provided inspiration. Family always assists: beginning with one's parents and siblings: Mom and Dad, Marie Mangino, RN PNP; Jim Whitman, PhD; John Whitman; and Patricia Whitman, JD. Lastly, I have the honor of stating that all of my children, Janet Abbott; David J. Whitman, JD; Thomas R. Whitman, and Joseph R. Whitman and seven grandchildren have provided both the wonder and joy that helps me continue to teach and to learn. Lynn, my wife, a patient mother, and college instructor has now started her doctorate work. v Table of Contents TITLE PAGE ................................................................................................................................ 1 ABSTRACT ................................................................................................................................... ii DEDICATION.............................................................................................................................. iii ACKNOWLEDGEMENTS ........................................................................................................ iv LIST OF TABLES ..................................................................................................................... viii LIST OF FIGURES ..................................................................................................................... ix CHAPTER 1: INTRODUCTION ................................................................................................ 1 Objectives: ................................................................................................................................. 3 CHAPTER 2: REVIEW OF LITERATURE ............................................................................. 4 Fallout Defined .......................................................................................................................... 4 Earliest Atomic Tests ................................................................................................................ 5 Nuclear Weapon Designs ........................................................................................................ 10 Nuclear Weapons Tests .......................................................................................................... 11 Unintentional Effects from Testing ....................................................................................... 13 Later Atomic Tests, 1958 -1962 ............................................................................................. 14 Health Impacts from Fallout.................................................................................................. 20 Chernobyl and Fukushima Reactor Failures ....................................................................... 31 Behavior of Fallout Isotopes in the Biosphere ...................................................................... 35 REFERENCES ........................................................................................................................ 38 CHAPTER 3: EXPERIMENTAL METHODS........................................................................ 52 Site Selection for Soil Sampling ............................................................................................. 52 Sampling Location Requirements ......................................................................................... 54 Sample Collection, Preparation and Analysis ...................................................................... 54 Statistical Analysis .................................................................................................................. 58 REFERENCES ........................................................................................................................ 59 CHAPTER 4: RESULTS AND DISCUSSION ........................................................................ 60 Cesium-137 Retention as Affected by Precipitation ............................................................ 67 Cesium-137 Retention as Affected by Soil Clay Content .................................................... 70 Cesium-137 Retention as Affected by Combined Rainfall and Soil Clay Content ........... 74 vi Cesium-137 Deposition by Latitude ...................................................................................... 75 Potassium-40 and Lead-210 in Indiana Soil ......................................................................... 75 Statistical Considerations between Cs-137, Pb-210 and K-40 ............................................ 76 Soil pH Values ......................................................................................................................... 78 Limitations of the Current Study .......................................................................................... 79 REFERENCES ........................................................................................................................ 80 CHAPTER 5: SUMMARY AND CONCLUSIONS ...............................................................

Dissertation Advisor: Charles Rosenberg Jennifer Christine Thomson From Wilderness to the Toxic Environment: Health in American Environmental Politics, 1945-Present Abstract This dissertation joins the history of science and medicine with environmental history to explore the language of health in environmental politics. Today, in government policy briefs and mission statements of environmental non-profits, newspaper editorials and activist journals, claims about the health of the planet and its human and non-human inhabitants abound. Yet despite this rhetorical ubiquity, modern environmental politics are ideologically and organizationally fractured along the themes of whose health is at stake and how that health should be protected.

  • The Electoral Consequences of Nuclear Fallout: Evidence from Chernobyl
    Working Paper 2020:23 Department of Economics School of Economics and Management The Electoral Consequences of Nuclear Fallout: Evidence from Chernobyl Adrian Mehic November 2020 The electoral consequences of nuclear fallout: Evidence from Chernobyl Adrian Mehic ∗ This version: November 19, 2020 Abstract What are the political effects of a nuclear accident? Following the 1986 Chernobyl disaster, environmentalist parties were elected to parliaments in several nations. This paper uses Chernobyl as a natural experiment creating variation in radioactive fallout exposure over Sweden. I match municipality-level data on cesium ground contamination with election results for the anti-nuclear Green Party, which was elected to parliament in 1988. After adjusting for pre-Chernobyl views on nuclear power, the results show that voters in high-fallout areas were more likely to vote for the Greens. Additionally, using the exponential decay property of radioactive isotopes, I show a persistent, long-term effect of fallout on the green vote. However, the Chernobyl-related premium in the green vote has decreased substantially since the 1980s. Detailed individual-level survey data further suggests that the results are driven by a gradually decreasing resistance to nuclear energy in fallout-affected municipalities.

  • Feasibility of Determining the Health Consequences Of
    Chapter 3 Estimation of Doses from Fallout Contents: This chapter addresses external and internal radiation exposure from fallout originating at the Nevada Test Site and at other sites worldwide. The methods used to estimate doses and the principal findings are presented. 3.1 Introduction This chapter presents dosimetric methods and results of calculations to estimate radiation doses that could have been received by Americans living in the contiguous United States as result of exposure to radioactive fallout originating at the Nevada Test Site and at other nuclear testing sites worldwide. It should be noted that these methods are based on data collected over more than four decades but primarily on the experience acquired in dose reconstruction during the past decade and a half. Crude methods of estimating doses have been used for this feasibility study. In some cases – particularly for the case of shorter-lived radionuclides (e.g., 131I) in global fallout – the doses presented may be in error by as much as an order of magnitude. Future work could likely improve the precision of these calculations, however. Because of the low precision of some of the dose estimates presented, the doses should not be used to make a claim of individual health effects or increases in health effects among subpopulations. The goal of these calculations was to show feasibility only, and in many cases the possible degree of error of the doses has not been evaluated. Thus, the usefulness of the doses presented here is limited only to very approximate evaluations of overall (that is, national) health detriment. Even though county-specific deposition densities and doses were computed and presented in a series of maps, those county-specific estimates are uncertain, and individual county values should not be used for definitive risk assessments until further refinements are made and the degree of possible error is evaluated in detail.

  • THESIS the RATE of DECAY of FRESH FISSION PRODUCTS from a NUCLEAR REACTOR Submitted by David J. Dolan Department of Environment
    THESIS THE RATE OF DECAY OF FRESH FISSION PRODUCTS FROM A NUCLEAR REACTOR Submitted by David J. Dolan Department of Environmental and Radiological Health Sciences In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Spring 2013 Master’s Committee: Advisor: Thomas Johnson Alexander Brandl Rosemond Desir ABSTRACT THE RATE OF DECAY OF FRESH FISSION PRODUCTS FROM A NUCLEAR REACTOR Determining the rate of decay of fresh fission products from a nuclear reactor is complex because of the number of isotopes involved, different types of decay, half-lives of the isotopes, and some isotopes decay into other radioactive isotopes. Traditionally, a simplified rule of t-1.2 or 7s and 10s is used to determine the dose rate from nuclear weapons and can be to estimate the dose rate from fresh fission products of a nuclear reactor. An experiment was designed to determine the dose rate with respect to time from fresh fission products of a nuclear reactor. The 10 !"#$%&!' experiment exposed 0.5 grams of U308 to a fast neutron fluence rate of 1.09 ! 10 and a !"!!! thermal neutron fluence rate of 7.5 ! 1011 !"#$%&!' from a TRIGA Research Reactor (Lakewood, !"!!! CO) for ten minutes. The dose rate from the fission products was measured by four Mirion DMC 2000XB electronic personal dosimeters over a period of six days. The resulting dose rate with respect to time had a slope of t-1.024 and could be simplified to a rule of 10s: the dose rate of fresh fission products from a nuclear reactor decreases by a factor of 10 for every 10 units of time.

Most of these pictures were taken more than half a century ago, when above- ground atmospheric testing was still common practice among nuclear powers. Things have improved significantly since then: explosive nuclear tests went underground from the mid-1960s onwards, and from 1998 onwards, only North Korea resorted to nuclear testing. All major nuclear powers – the US, Russia, France, the United Kingdom, China, India and Pakistan - declared some sort of testing moratorium before the end of the 20th century, and some of them signed or even ratified the Comprehensive Test Ban Treaty (CTBT) afterwards.
