Nevada National Security Site
The Nevada National Security Site (N2S2 or NNSS), known as the Nevada Test Site (NTS) until 2010, is a United States Department of Energy (DOE) reservation located in southeastern Nye County, Nevada, about 65 miles (105 km) northwest of the city of Las Vegas. Formerly known as the Nevada Proving Grounds, the site was established in 1951 for the testing of nuclear devices. It covers approximately 1,360 square miles (3,500 km2) of desert and mountainous terrain. Nuclear weapons testing at the site began with a 1-kiloton-of-TNT (4.2 TJ) bomb dropped on Frenchman Flat on January 27, 1951. Over the subsequent four decades, over 1,000 nuclear explosions were detonated at the site. Many of the iconic images of the nuclear era come from the site. During the 1950s, the mushroom clouds from the 100 atmospheric tests could be seen from almost away. The city of Las Vegas experienced noticeable seismic effects, and the mushroom clouds, which could be seen from the downtown hot ...

Operation Buster–Jangle
Operation Buster–Jangle was a series of seven (six atmospheric, one Explosion crater, cratering) nuclear weapons tests conducted by the United States in late 1951 at the Nevada Test Site. ''Buster–Jangle'' was the first joint test program between the United States Department of Defense, DOD (Operation ''Buster'') and Los Alamos National Laboratory, Los Alamos National Laboratories (Operation ''Jangle''). As part of Operation ''Buster'', 6,500 troops were involved in the Desert Rock exercises, Operation Desert Rock I, II, and III exercises in conjunction with the tests.Operation Buster–Jangle Fact Sheet , Defense Threat Reduction Agency The last two tests, Operation ''Jangle'', evaluated the cratering effects of low-yield nuclear devices. This series preceded ''Operation Tumbler–Snapper'' a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as ''Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Feller (nuclear Tests)
Little Feller II and Little Feller I were code names for a set of nuclear tests undertaken by the United States at the Nevada Test Site on July 7 and 17, 1962 as part of Operation Sunbeam. They were both tests of stockpiled W54 warheads, the smallest nuclear warheads known to have been produced by the United States, used in both the Davy Crockett warhead and the Special Atomic Demolition Munition. In Little Feller II (July 7), the warhead was suspended only three feet above the ground and had a yield equivalent to . In Little Feller I (July 17), the warhead was launched as a Davy Crockett device from a stationary 155 millimeter launcher and set to detonate between above the ground around from the launch point, with a yield of . This test was performed in conjunction with Operation Ivy Flats, a simulated military environment, and was observed by Attorney General Robert F. Kennedy and presidential adviser General Maxwell D. Taylor. Little Feller I was the last near-ground at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 58,413 people (at the 2018 World Bank Census) is spread out over five islands and 29 coral atolls, comprising 1,156 individual islands and islets. The capital and largest city is Majuro. It has the largest portion of its territory composed of water of any sovereign state, at 97.87%. The islands share maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and Federated States of Micronesia to the west. About 52.3% of Marshall Islanders (27,797 at the 2011 Census) live on Majuro. In 2016, 73.3% of the population were defined as being "urban". The UN also indicates a population d ...

Pacific Proving Grounds
The Pacific Proving Grounds was the name given by the United States government to a number of sites in the Marshall Islands and a few other sites in the Pacific Ocean at which it conducted nuclear testing between 1946 and 1962. The U.S. tested a nuclear weapon (codenamed Able) on Bikini Atoll on June 30, 1946. This was followed by Baker on July 24, 1946 (dates are Universal Time, local dates were July 1 and 25, respectively). On July 18, 1947, the United States secured an agreement with the United Nations to govern the islands of Micronesia as the Trust Territory of the Pacific Islands, a strategic trusteeship territory. This is the only such trusteeship ever granted by the United Nations to the United States. The Trust Territory comprised about 2,000 islands spread over of the North Pacific Ocean. Five days later, the United States Atomic Energy Commission established the Pacific Proving Grounds. The United States conducted 105 atmospheric and underwater (i.e., not undergrou ...

Subsidence Crater
__NOTOC__ A subsidence crater is a hole or depression left on the surface of an area which has had an underground (usually nuclear) explosion. Many such craters are commonly present at bomb testing areas; one notable example is the Nevada Test Site, which was historically used for nuclear weapons testing over a period of 41 years. Subsidence craters are created as the roof of the cavity caused by the explosion collapses. This causes the surface to depress into a sink (which subsidence craters are sometimes called; see sink hole). It is possible for further collapse to occur from the sink into the explosion chamber. When this collapse reaches the surface, and the chamber is exposed atmospherically to the surface, it is referred to as a ''chimney''. It is at the point that a chimney is formed through which radioactive fallout may reach the surface. At the Nevada Test Site, depths of were used for tests. When the material above the explosion is solid rock, then a mound may be fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
