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. -
Making a Manhattan Project National Historical Park
Atomic Heritage Foundation Preserving and Interpreting Manhattan Project History & Legacy Making A manhattan Project National Historical Park AnnualAnnual ReportReport 2010 Why should We Preserve the Manhattan Project? “The factories and bombs that Manhattan Project scientists, engineers, and workers built were physical objects that depended for their operation on physics, chemistry, metallurgy, and other natural sciences, but their social reality - their meaning, if you will - was human, social, political. We preserve what we value of the physical past because it specifically embodies our social past. When we lose parts of our physical past, we lose parts of our common social past as well.” “The new knowledge of nuclear energy has undoubtedly limited national sovereignty and scaled down the destructiveness of war. If that’s not a good enough reason to work for and contribute to the Manhattan Project’s historic preservation, what would be?” -Richard Rhodes, “Why We Should Preserve the Manhattan Project,” Bulletin of the Atomic Scientists, May/June 2006 Remnant of the K-25 plant during the demolition of the east wing.

INTERSCALAR VEHICLES for an AFRICAN ANTHROPOCENE: on Waste, Temporality, and Violence
INTERSCALAR VEHICLES FOR AN AFRICAN ANTHROPOCENE: On Waste, Temporality, and Violence GABRIELLE HECHT Stanford University http://orcid.org/0000-0003-1445-0785 Brightly painted concrete houses, equipped with running water and elec- tricity, arranged in dozens of identical rows: this photograph (Figure 1) depicts the newly built company town of Mounana in eastern Gabon. The road is clean, the children happy. In the late 1970s, this image represented Gabonese “expec- tations of modernity” (Ferguson 1999) through national and corporate projects. By the end of this essay, I hope you will also see it as an image of the African Anthropocene. The idea of an African Anthropocene may seem like a paradox. After all, the biggest appeal of the idea of the Anthropocene has been its “planetarity” (DeLoughrey 2014). For some geologists, the Anthropocene signals the start of a new epoch, one in which humans permanently mark the stratigraphic record with their “technofossils” (Zalasiewicz et al. 2014). Other earth scientists adopt the notion to signal humanity’s catastrophic effects on the planet’s physical and biochemical systems. During the past decade, the term has become a “charismatic mega-category” (Reddy 2014) across the humanities, arts, and natural and social sciences (Steffen et al. 2011; Ellsworth and Kruse 2012). Inevitably, debates rage about origins and nomenclature. Did the Anthropocene begin with the dawn of human agriculture? Or with the Columbian exchange of the sixteenth and sev- enteenth centuries? How about the start of European industrialization in the eigh- CULTURAL ANTHROPOLOGY, Vol. 33, Issue 1, pp. 109–141, ISSN 0886-7356, online ISSN 1548-1360. -

Sawyer Jr. (Albuquerque: University of New Mexico Press, 2005. ix + 170 pp. Halftones, bibliography, index. $14-95 paper, ISBN 0-8263-3640-X.) This book details the personal journey ofEliseo "Cheo" Torres, a profes sor and vice president ofstudent affairs at the University ofNew Mexico, to understand the healing practices of Mexican and Mexican American cul tures, and to document the lives of important Mexican healers such as El Nino Fidencio, don Pedrito Jaramillo, Chenchito Alvarado, and Teresita Urrea. Torres also documents the work oflocal healers such as his mother and father, dona Marfa, the neighborhood curandera, and dona Juana, a partera (midwife). Curanderismo is a traditional art ofhealing that predates doctors trained in western medicine, and it flourishes in areas where doc tors are scarce and where people cannot afford medical treatment. Torres wants to understand not only the history ofcuranderismo, butalso to articu late the cures utilized, their social and cultural implications, and the spiri tual dimension involved in healing. -

Box 25287, Denver, CO 80225-0287 Description Established on November 10, 2015, Manhattan Project National Historical Park preserves, interprets, and facilitates access to key historic resources associated with the Manhattan Project. The Manhattan Project was a massive, top-secret national mobilization of scientists, engineers, technicians, and military personnel charged with producing a deployable atomic weapon during World War II. It resulted in the first successful test of an atomic device on July 16, 1945, a few weeks before the United States dropped atomic bombs on Hiroshima and Nagasaki, Japan. Coordinated by the U.S. Army, Manhattan Project activities took place in numerous locations across the United States. The park is managed through a collaborative partnership by the National Park Service and the U.S. Department of Energy, and incorporates three of the Manhattan Project’s most significant locations: Oak Ridge, Tennessee; Los Alamos, New Mexico; and Hanford, Washington. The unprecedented scientific and industrial activities of the Manhattan Project displaced many communities with thousands of people to make way for the rapid construction of Manhattan Project infrastructure. In addition to its MANHATTAN PROJECT NATIONAL HISTORICAL PARK industrial plants, Hanford the U.S. government Washington built large residential neighborhoods to ! support the tens of thousands of workers who moved to these sites to support the project. -

Tickling the Sleeping Dragon's Tail: Should We Resume Nuclear Testing?
TICKLING THE SLEEPING DRAGON’S TAIL Should We Resume Nuclear Testing? National Security Report Michael Frankel | James Scouras | George Ullrich TICKLING THE SLEEPING DRAGON’S TAIL Should We Resume Nuclear Testing? Michael Frankel James Scouras George Ullrich Copyright © 2021 The Johns Hopkins University Applied Physics Laboratory LLC. All Rights Reserved. “Tickling the sleeping dragon’s tail” is a metaphor for risking severe consequences by taking an unnecessary provocative action. Its origin can be traced to the last year of the Manhattan Project at Los Alamos National Laboratory (LANL) in 1946. When investigating the critical mass of plutonium, LANL scientists usually brought two halves of a beryllium reflecting shell surrounding a fissile core closer together, observing the increase in reaction rate via a scintillation counter. They manually forced the two half-shells closer together by gripping them through a thumbhole at the top, while as a safety precaution, keeping the shells from completely closing by inserting shims. However, the habit of Louis Slotin was to remove the shims and keep the shells separated by manually inserting a screwdriver. Enrico Fermi is reported to have warned Slotin and others that they would be “dead within a year” if they continued this procedure. One day the screwdriver slipped, allowing the two half-shells to completely close, and the increased reflectivity drove the core toward criticality. Slotin immediately flipped the top half-shell loose with a flick of the screwdriver, but by then he had endured -

Biographical Memoir COPYRIGHT 2007 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. ANTHONY L. TURKEVICH July 23, 1916–September 7, 2002 BY R. STEPHEN BERRY, ROBERT N. CLAYTON, GEORGE A. COWAN, AND THANASIS E. ECONOMOU NTHONY LEONID (“TONY”) TURKEVICH WAS born in New York A City in 1916, one of three children of a Russian Ortho- dox clergyman, Leonid Turkevich, who became head of the entire Russian Orthodox Church in North America and Ja- pan. Tony went to Dartmouth College for his undergradu- ate studies, completing his B.A. in 1937. From there he went to Princeton, working with J. Y. Beach on structures of small molecules for his Ph.D., which he received in 1940. Turkevich then went to Robert Mulliken in the Department of Physics at the University of Chicago as a research assis- tant, studying molecular spectroscopy. He also worked on the radiochemistry of fission products. Soon after the outbreak of World War II Tony joined the Manhattan Project as one of its youngest scientists. In 1942 he worked at Columbia and the next year went to the Metallurgical Laboratory at the University of Chicago where he stayed until 1945, when he moved on to Los Alamos. During that period Turkevich worked closely with Charles P. Smyth and Enrico Fermi.
