Nemchin1,2 6 7 *Corresponding author, email address: [email protected] 8 9 1Department of Geosciences, Swedish Museum of Natural History, SE-104 05 10 Stockholm, Sweden 11 2 Department of Applied Geology, Curtin University, Perth, WA 6845, Australia 12 13 Abstract 14 15 The Pb isotope composition of a nuclear fallout debris particle has been directly 16 measured in post-detonation materials produced during the Trinity nuclear test by a 17 secondary ion mass spectrometry (SIMS) scanning ion image technique (SII). This 18 technique permits the visual assessment of the spatial distribution of Pb and can be used 19 to obtain full Pb isotope compositions in user-defined regions in a 70 µm x 70 µm 20 analytical window. In conjunction with BSE and EDS mapping of the same particle, the 21 Pb measured in this fallout particle cannot be from a major phase in the precursor arkosic 22 sand. Similarly, the Pb isotope composition of the particle is resolvable from the 23 surrounding glass at the 2σ uncertainty level. The Pb isotope composition measured in 24 the particle here is in excellent agreement with that inferred from measurements of green 25 and red trinitite, suggesting that these types of particles are responsible for the Pb isotope 26 compositions measured in both trinitite glasses. 27 28 29 Keywords: 30 31 Trinitite, Trinity Test, Post Detonation Nuclear Forensics, Pb isotopes, SIMS, Scanning 32 Ion Imaging, Fallout Debris, Forensics 33 34 35 Introduction 36 37 In the event of a non-state sanctioned nuclear attack, forensic investigations will 38 be necessary to determine the provenance of the weapon and the materials used in 39 construction of the device. -

If technology is not the only driver in the evolution of warfare, it is the enabler, not to say the trigger, of most of the changes that occurred at the turning point between generations. For a country like Switzerland, Technology Foresight is paramount to identify the opportuni- ties and threats a technology can represent for the different military capabilities building our national armed forces. Rather than picking winners, the Technology Foresight program must provide a comprehensive overview to ensure an early warning about novel relevant technological advances. Identifying potentialities provides the time to build the necessary competences, skills and expertise, in the various fields. In that sense, Technology Foresight must be an integrated element of the doctrine, planing and procurement processes of the armed forces. Only with this strategic futuristic vision, the Swiss armed forces are able to handle, economi- cally and operatively, the evolutions and challenges to come. -

Radiation Poisoning , Also Called Radiation Sickness Or a Creeping Dose , Is a Form of Damage to Organ Tissue Due to Excessive Exposure to Ionizing Radiation
Radiation poisoning , also called radiation sickness or a creeping dose , is a form of damage to organ tissue due to excessive exposure to ionizing radiation . The term is generally used to refer to acute problems caused by a large dosage of radiation in a short period, though this also has occurred with long term exposure. The clinical name for radiation sickness is acute radiation syndrome ( ARS ) as described by the CDC .[1][2][3] A chronic radiation syndrome does exist but is very uncommon; this has been observed among workers in early radium source production sites and in the early days of the Soviet nuclear program. A short exposure can result in acute radiation syndrome; chronic radiation syndrome requires a prolonged high level of exposure. Radiation exposure can also increase the probability of contracting some other diseases, mainly cancer , tumours , and genetic damage . These are referred to as the stochastic effects of radiation, and are not included in the term radiation sickness. The use of radionuclides in science and industry is strictly regulated in most countries (in the U.S. by the Nuclear Regulatory Commission ). In the event of an accidental or deliberate release of radioactive material, either evacuation or sheltering in place are the recommended measures. Radiation sickness is generally associated with acute (a single large) exposure. [4][5] Nausea and vomiting are usually the main symptoms. [5] The amount of time between exposure to radiation and the onset of the initial symptoms may be an indicator of how much radiation was absorbed. [5] Symptoms appear sooner with higher doses of exposure. -

Prof. Wolfgang Kubin accepted me as his Ph.D student and in these years he warmly helped me a lot, not only with my research but also with my life. In every meeting, I am impressed by his personality and erudition deeply. I remember one time in his seminar he pointed out my minor errors in the speech paper frankly and patiently. I am indulged in his beautiful German and brilliant poetry. His translations are full of insightful wisdom. Every time when I meet him, I hope it is a long time. I am so grateful that Prof. Ralph Kauz in the past years gave me unlimited help. In his seminars, his academic methods and sights opened my horizons. Usually, he supported and encouraged me to study more fields of research. -

Nuclear Fallout and Intelligence As Secrets, Problems, and Limitations on the Arms Race, 1940-1964
© Copyright 2016 Michael R. Lehman NUISANCE TO NEMESIS: NUCLEAR FALLOUT AND INTELLIGENCE AS SECRETS, PROBLEMS, AND LIMITATIONS ON THE ARMS RACE, 1940-1964 BY MICHAEL R. LEHMAN DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in History in the Graduate College of the University of Illinois at Urbana-Champaign, 2016 Urbana, Illinois Doctoral Committee: Professor Lillian Hoddeson, Chair Professor Kristin Hoganson, Co-Chair Professor Michael Weissman Professor Robert Jacobs, Hiroshima City University Abstract Fallout sampling and other nuclear intelligence techniques were the most important sources of United States strategic intelligence in the early Cold War. Operated as the Atomic Energy Detection System by a covert Air Force unit known as AFOAT-1, the AEDS detected emissions and analyzed fallout from Soviet nuclear tests, as well as provided quantitative intelligence on the size of the Russian nuclear stockpile. Virtually unknown because the only greater Cold War secret than nuclear weapons was intelligence gathered about them, data on the Soviet threat produced by AFOAT-1 was an extraordinary influence on early National Intelligence Estimates, the rapid growth of the Strategic Air Command, and strategic war plans. Official guidance beginning with the first nuclear test in 1945 otherwise suggested fallout was an insignificant effect of nuclear weapons. Following AFOAT-1’s detection of Soviet testing in fall 1949 and against the cautions raised about the problematic nature of higher yield weapons by the General Advisory Committee, the Atomic Energy Commission’s top scientific advisers, President Harry Truman ordered the AEC to quickly build these extraordinarily powerful weapons, testing the first in secrecy in November 1952.
