Federation Of American Scientists
The Federation of American Scientists (FAS) is an American nonprofit global policy think tank with the stated intent of using science and scientific analysis to attempt to make the world more secure. FAS was founded in 1945 by a group of scientists, some of whom had previously contributed to the development of nuclear weapons in the Manhattan Project. The Federation of American Scientists states that it aims to reduce the amount of nuclear weapons that are in use, and prevent nuclear and radiological terrorism. It says it aims to present high standards for nuclear energy's safety and security, illuminate government secrecy practices, as well as track and eliminate the global illicit trade of conventional, nuclear, biological and chemical weapons. With 100 sponsors, the Federation of American Scientists says that it promotes a safer and more secure world by developing and advancing solutions to important science and technology security policy problems by educating the public and ...

Nuclear Safety And Security
Nuclear safety is defined by the International Atomic Energy Agency (IAEA) as "The achievement of proper operating conditions, prevention of accidents or mitigation of accident consequences, resulting in protection of workers, the public and the environment from undue radiation hazards". The IAEA defines nuclear security as "The prevention and detection of and response to, theft, sabotage, unauthorized access, illegal transfer or other malicious acts involving nuclear materials, other radioactive substances or their associated facilities". This covers nuclear power plants and all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and military uses. The nuclear power industry has improved the safety and performance of reactors, and has proposed new and safer reactor designs. However, a perfect safety cannot be guaranteed. Potential sources of problems include human errors and external ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Reaction
In nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two atomic nucleus, nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides. Thus, a nuclear reaction must cause a transformation of at least one nuclide to another. If a nucleus interacts with another nucleus or particle, they then separate without changing the nature of any nuclide, the process is simply referred to as a type of nuclear scattering, rather than a nuclear reaction. In principle, a reaction can involve more than two particles collision, colliding, but because the probability of three or more nuclei to meet at the same time at the same place is much less than for two nuclei, such an event is exceptionally rare (see triple alpha process for an example very close to a three-body nuclear reaction). The term "nuclear reaction" may refer either to a change in a nuclide induced by collision with another particle or to a spontaneous change of a ...

May-Johnson Bill
The Atomic Energy Act of 1946 (McMahon Act) determined how the United States would control and manage the nuclear technology it had jointly developed with its World War II allies, the United Kingdom and Canada. Most significantly, the Act ruled that nuclear weapon development and nuclear power management would be under civilian, rather than military control, and established the United States Atomic Energy Commission for this purpose. It was sponsored by Senator Brien McMahon, a Democrat from Connecticut, who chaired the United States Senate Special Committee on Atomic Energy, and whose hearings in late 1945 and early 1946 led to the fine tuning and passing of the Act. The Senate passed the Act unanimously through voice vote, and it passed the House of Representatives 265–79. Signed into law by President Harry S. Truman on August 1, 1946, it went into effect on January 1, 1947, and the Atomic Energy Commission assumed responsibility for nuclear energy from the wartime Manh ...

Nuclear Disarmament
Nuclear disarmament is the act of reducing or eliminating nuclear weapons. Its end state can also be a nuclear-weapons-free world, in which nuclear weapons are completely eliminated. The term ''denuclearization'' is also used to describe the process leading to complete nuclear disarmament. Disarmament and non-nuclear proliferation, proliferation treaties have been agreed upon because of the extreme danger intrinsic to nuclear war and the possession of nuclear weapons. Proponents of nuclear disarmament say that it would lessen the probability of nuclear war occurring, especially considering accidents or retaliatory strikes from false alarms. Critics of nuclear disarmament say that it would undermine Deterrence theory, deterrence and make conventional wars more common. Organizations List of anti-nuclear groups, Nuclear disarmament groups include the Campaign for Nuclear Disarmament, Peace Action, Pugwash Conferences on Science and World Affairs, Greenpeace, Soka Gakkai Internati ...

News Media
The news media or news industry are forms of mass media that focus on delivering news to the general public. These include News agency, news agencies, newspapers, news magazines, News broadcasting, news channels etc. History Some of the first news circulations occurred in Renaissance Europe. These handwritten newsletters, circulated among merchants, contained news about wars, economic conditions, and social customs. Newsletters were very scarce and no two were the same as they were all hand written, until the invention of the printing press by Johannes Gutenberg in 1440. With movable type and ink, newspapers were now able to be mass produced for cheap. The first printed news appeared by the late 1400s in German pamphlets, which contained content that was often highly sensationalized. The first newspaper written in English was ''The Weekly News,'' published in London in 1621. Several papers followed in the 1640s and 1650s. In 1690, the first American newspaper was published by ...

Robert R
Robert Lee Rayford (February 3, 1953 – May 15, 1969), sometimes identified as Robert R. due to his age, was an American teenager from Missouri who has been suggested to represent the earliest confirmed case of HIV/AIDS in North America. This is based on evidence published in 1988 in which the authors claimed that medical evidence indicated that he was "infected with a virus closely related or identical to human immunodeficiency virus type 1." Rayford died of pneumonia, but his other symptoms baffled the doctors who treated him. A study published in 1988 reported the detection of antibodies against HIV. Results of testing for HIV genetic material were reported at a scientific conference in Australia in 1999. However, the data has never been published in a peer-reviewed medical or scientific journal. No photos of Rayford are known to exist. Background Robert Rayford was born on February 3, 1953, in St. Louis, Missouri. As a single parent, his mother Constance had to rais ...

Melba Phillips
Melba Newell Phillips (February 1, 1907 – November 8, 2004) was an American physicist and a pioneer science educator. One of the first doctoral students of J. Robert Oppenheimer at the University of California, Berkeley, Phillips completed her PhD in 1933, a time when few women could pursue careers in science. In 1935, Oppenheimer and Phillips published their description of the Oppenheimer–Phillips process, an early contribution to nuclear physics that explained the behavior of accelerated nuclei of radioactive hydrogen atoms. Phillips was also known for her refusal to cooperate with a U.S. Senate judiciary subcommittee's investigation on internal security during the McCarthy era which led to her dismissal from her professorship at Brooklyn College, where she was a professor of science from 1938 until 1952. (The college publicly and personally apologized to Phillips for the dismissal in 1987.) Phillips also taught at the University of Minnesota (1941–44) and served as as ...

Project Y
The Los Alamos Laboratory, also known as Project Y, was a secret scientific laboratory established by the Manhattan Project and overseen by the University of California during World War II. It was operated in partnership with the United States Army. Its mission was to design and build the first atomic bombs. J. Robert Oppenheimer was its first director, serving from 1943 to December 1945, when he was succeeded by Norris Bradbury. In order to enable scientists to freely discuss their work while preserving security, the laboratory was located on the isolated Pajarito Plateau in Northern New Mexico. The wartime laboratory occupied buildings that had once been part of the Los Alamos Ranch School. The development effort initially focused on a gun-type fission weapon using plutonium called Thin Man. In April 1944, the Los Alamos Laboratory determined that the rate of spontaneous fission in plutonium bred in a nuclear reactor was too great due to the presence of plutonium-240 and ...

Clinton Engineer Works
The Clinton Engineer Works (CEW) was the production installation of the Manhattan Project that during World War II produced the enriched uranium used in the 1945 bombing of Hiroshima, as well as the first examples of reactor-produced plutonium. It consisted of production facilities arranged at three major sites, various utilities including a power plant, and the town of Oak Ridge. It was in East Tennessee, about west of Knoxville, and was named after the town of Clinton, to the north. The production facilities were mainly in Roane County, and the northern part of the site was in Anderson County. The Manhattan District Engineer, Kenneth Nichols, moved the Manhattan District headquarters from Manhattan to Oak Ridge in August 1943. During the war, CEW's advanced research was managed for the government by the University of Chicago. Construction workers were housed in a community known as Happy Valley. Built by the Army Corps of Engineers in 1943, this temporary communit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
