The Effect of Chemical Incidents on First Responders
2019 The Effect of Chemical Incidents on First Responders: An Interview with Bruce Evans (MPA, NRP, CFOD, SEMSO), Fire Chief, Upper Pine River Fire Protection District A massive leak of liquefied chlorine gas created a dangerous cloud over the city of Henderson, NV, in the early morning hours of May 6, 1991. Over 200 people (including firefighters) were examined at a local hospital for respiratory distress caused by inhalation of the chlorine and approximately 30 were admitted for treatment. Approximately 700 individuals were taken to shelters, and between 2,000 and 7,000 individuals were evacuated from the area. ASPR TRACIE interviewed Chief Bruce Evans (who was a firefighter- paramedic at the time of the incident), asking him to share his my first large-scale incident: the experiences and highlight how the PEPCON explosion.

Show #1204 "Alien Invasion" Premiered November 6, 2001 THE SILENCE OF THE BIRDS GREEN INVADER THE SILKEN TREE EATERS DUST BUSTING TEASE ALAN ALDA Some time in the 1940s, a brown tree snake hitched a ride aboard a US Air Force plane in New Guinea, and it traveled across the Pacific to the island of Guam. As a result, Guam lost all its native bird life. On this edition of Scientific American Frontiers, global attacks by alien species. ALAN ALDA (NARRATION) The European gypsy moth has been steadily transforming America's forests, and now the Asian longhorned beetle could do the same thing. An African fungus crossed the Atlantic, to cause a damaging disease in Caribbean coral. And a Caribbean weed is smothering marine life in the Mediterranean, and it now threatens the California coast. ALAN ALDA I'm Alan Alda. Join me now for Alien Invasion. SHOW INTRO ALAN ALDA (NARRATION) It's a tranquil scene on the coast. A couple of guys are diving -- checking out life on the lagoon floor. People are boating. Actually I know who that is out there. She's Rachel Woodfield, a marine biologist, and she's bringing in a bag of that weed the divers were looking at. ALAN ALDA Hiya, Rachel. RACHEL WOODFIELD Hiya. ALAN ALDA Is that it, there? RACHEL WOODFIELD This is it right here. ALAN ALDA (NARRATION) But the weed is not as nice as it might seem. ALAN ALDA We're at Agua Hedionda Lagoon, just north of San Diego on the California coast. The divers out there are trying to get rid of every last shred of this stuff that they can find. -
Fallout Model for the Robust Nuclear Earth Penetrator Blake Purnell the Radioactive Cloud Model
Fallout Model for the Robust Nuclear Earth Penetrator Blake Purnell Modeling radioactive fallout from nuclear explosions requires a description of the radioactive cloud and base surge and an atmospheric transport model for the cloud dispersion. The atmospheric transport model is independent of the radioactive nature of the dust and I will stick to a simple model in this study. The Radioactive Cloud Model Radioactive Release The first stage in understanding the fallout from a nuclear explosion is to estimate the amount of radioactivity released into the atmosphere. For external exposure to radiation, the main threat is from gamma-rays. The average gamma-ray activity1 produced in a nuclear explosion has been calculated as 530 megacuries per kiloton of fission yield at one hour after the explosion, with an average photon energy of 0.7 MeV. The data available on underground nuclear tests focuses on the fraction of the total activity found in “early” or “close-in” fallout ( Fc ), which measures only those particles that have been deposited in the first 24 2 hours . The fraction of the total activity released into the atmosphere ( f rel ) is greater than what appears in 3 the early fallout ( f rel > Fc ). The fraction Fc is dependant on the scaled depth of burst . A summary of the activity release data available for U.S. and Soviet underground tests are shown in Tables 1, Table 2, and Figure 1.

In the Shadow of the Mushroom Cloud: Nuclear Testing, Radioactive Fallout and Damage to U.S. Agriculture
In the Shadow of the Mushroom Cloud: Nuclear Testing, Radioactive Fallout and Damage to U.S. Agriculture September 1, 2017 Abstract In the 1950s the United States conducted scores of nuclear tests at the Nevada Test Site (NTS). Each test created tremendous quantities of harmful radioactive material and much of this material deposited across the country with precipitation. This paper is the first in the economics literature to measure some of the external costs of NTS activities. I find that fallout from nuclear tests adversely affected U.S. agriculture for large areas of the country. These empirical results show that nuclear testing had much broader economic and environmental impact than previously thought. The Cold War saw the rapid development and deployment of nuclear weapons. To expedite its nuclear weapons program, the United States started to conduct atmospheric nuclear tests at the Nevada Test Site (NTS) in 1951. This deliberate policy decision created immense quantities of radioactive debris and much of this material rained down across the U.S.. One estimate places the total atmospheric release of radioactive material from the NTS from 1951 to 1963 at 12 billion Curies. In comparison, the partial nuclear meltdown at Chernobyl released approximately 81 million Curies of radioactive material (LeBaron, 1998). Knowledge regarding the impact of this pollution is limited to scientific and health studies conducted in the regions surrounding the NTS. Nuclear testing had large pollution externalities associated with it, but the magnitude and extent of the nationwide harm caused by NTS activities have yet to be measured. This paper quantifies one dimension of the external costs of these activities by studying the adverse effects of radioactive fallout on U.S. -
Joseph Conrad
Joseph Conrad Joseph Conrad (born Józef Teodor Konrad Korzeniowski, Joseph Conrad Polish: [ˈjuzɛf tɛˈɔdɔr ˈkɔnrat kɔʐɛˈɲɔfskʲi] ( listen); 3 December 1857 – 3 August 1924) was a Polish-British writer[1][note 1] regarded as one of the greatest novelists to write in the English language.[2] Though he did not speak English fluently until his twenties, he was a master prose stylist who brought a non-English sensibility into English literature.[note 2] Conrad wrote stories and novels, many with a nautical setting, that depict trials of the human spirit in the midst of what he saw as an impassive, inscrutable universe.[note 3] Conrad is considered an early modernist,[note 4] though his works contain elements of 19th-century realism.[3] His narrative style and anti-heroic characters[4] have influenced numerous authors, and many films have been adapted from, or inspired by, his works. Numerous writers and critics have commented that Conrad's fictional works, written largely in the first two decades of the 20th century, seem to have anticipated later world events.[5][6] Conrad in 1904 Writing near the peak of the British Empire, Conrad drew, among by George Charles Beresford other things, on his native Poland's national Born Józef Teodor Konrad [7]:290, 352[note 5] experiences and on his own experiences in the Korzeniowski French and British merchant navies, to create short stories and 3 December 1857 novels that reflect aspects of a European-dominated world— Berdychiv, Russian including imperialism and colonialism—and that profoundly Empire explore -
THE THEME of ISOLATION in the WORK of JOSEPH CONRAD By
THE THEME OF ISOLATION IN THE WORK OF JOSEPH CONRAD by RUTH E. McCONNELL B.A. University of British Columbia, 1954 A Thesis Submitted in Partial Fulfilment of The Requirements for the Degree of M.A. in the Department of ENGLISH We accept this thesis as conforming to the required standard THE UNIVERSITY OF BRITISH COLUMBIA April, 1958. ii ABSTRACT' Central in the work of Joseph Conrad is the theme of isolation, of the loneliness of man> arid of alienation from one's own kind, a theme which, in some form, dominates the work of many modern writers and thinkers. A study of the criticism of Conrad shows that this preoccupation with the isolated man has always been noticed and was early linked to Conrad's own position in the world ,as .an exile. Recent critics have delved more deeply into the subject, and have shown its relationship to the threatened break-up of society seen in the latter part of the nineteenth century, and have declared Conrad a forerunner of such modern authors, as G-ide, Eliot, Kafka, Malraux, among: others, in whose work the "exile" of man is. also a central thought. While- many critics have touched .upon this aspe.c.t of C.onrad's writings, I have felt that the theme is so central to Conrad's total outlook on life that a fuller analysis of this question was necessary for' an adequate appreciation and understanding of his writing. This thesis, then, is an endeavour to explore more fully the theme of isolation in C.onrad's books, to try to distinguish the various types of isolation he deals with and their- causes, and to link with this central theme the other beliefs—moral, political, and social—disclosed by Conrad in his work. -
Oxygen Isotope Composition of Trinitite Postdetonation Materials Elizabeth C
Article pubs.acs.org/ac Oxygen Isotope Composition of Trinitite Postdetonation Materials Elizabeth C. Koeman,* Antonio Simonetti, Wei Chen, and Peter C. Burns Department of Civil Engineering and Environment Engineering and Earth Sciences, University of Notre Dame, Notre Dame, Indiana 46556, United States *S Supporting Information ABSTRACT: Trinitite is the melt glass produced subsequent the first nuclear bomb test conducted on July 16, 1945, at White Sands Range (Alamagordo, NM). The geological background of the latter consists of arkosic sand that was fused with radioactive debris and anthropogenic materials at ground zero subsequent detonation of the device. Postdetonation materials from historic nuclear weapon test sites provide ideal samples for development of novel forensic methods for attribution and studying the chemical/isotopic effects of the explosion on the natural geological environment. In particular, the latter effects can be evaluated relative to their spatial distribution from ground zero. We report here δ18O(‰) values for nonmelted, precursor minerals phases (quartz, feldspar, calcite), “feldspathic-rich” glass, “average” melt glass, and bulk (natural) unmelted sand from the Trinity site. Prior to oxygen isotope analysis, grains/crystals were examined using scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) to determine their corresponding major element composition. δ18O values for bulk trinitite samples exhibit a large range (11.2−15.5‰) and do not correlate with activity levels for activation product 152Eu; the latter levels are a function of their spatial distribution relative to ground zero. Therefore, the slow neutron flux associated with the nuclear explosion did not perturb the 18O/16O isotope systematics. The oxygen isotope values do correlate with the abundances of major elements derived from precursor minerals present within the arkosic sand. -
