Nucluer Weapons

By Amounie Apr 13, 2013 700 Words
Citation| Information|| A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter; a modern thermonuclear weapon weighing little more than a thousand kilograms can produce an explosion comparable to the detonation of more than a billion kilograms of conventional high explosive.[1] Even small nuclear devices can devastate a city. Nuclear weapons are considered weapons of mass destruction, and their use and control has been a major aspect of international policy since their debut.|| The First Atomic Bomb Blast, 1945The events that took place in a remote area of New Mexico during the predawn hours of July 16, 1945 forever changed the world.Even before the bomb was tested, a second bomb was secretly dispatched to the Pacific for an attack on the Japanese city of Hiroshima.|| Total number of nuclear missiles built, 1951-present: 67,500Total number of nuclear bombers built, 1945-present: 4,680Total number and types of nuclear warheads and bombs built, 1945-1990: more than 70,000/65 typesNumber of secret Presidential Emergency Facilities built for use during and after a nuclear war: more than 75|| The medical effects of a nuclear blast upon humans can be put into four categories: the initial stage, the first 1-2 weeks, the greatest amount of deaths are in this period with 90% due to thermal injury and or blast effects and 10% due to supralethal radiation exposure, the intermediate stage from 3-8 weeks the deaths in this period are from ionization radiation in the median lethal range, and the late period lasting from 8-20 weeks, this period has some improvement in survivors condition and the delayed period from 20+ weeks. The last section is characterized by “numerous complications, mostly related to healing of thermal and mechanical injuries coupled with infertility, subfertility and blood disorders caused by radiation.” Also, ionizing radiation from fallout can cause genetic effects, birth defects, cancer cataracts and other effects in organs and tissue.|| ‘The explosive force of nuclear fission has changed everything except our modes of thinking and thus we drift towards unparalleled catastrophe. We shall require an entirely new pattern of thinking if humankind is to survive.’ Albert Einstein, 1946…. Continuation on Web Page|| Who Invented the Atomic Bomb?Lord Rutherford.Albert EinsteinEnrico Fermi.Robert Oppenheimer.( Explanation on Website.) || On August 6 and 9, 1945, the cities of Hiroshima and Nagasaki were destroyed by the first atomic bombs used in warfare.The first atomic bomb ever to be used in a military operation was dropped on the city of Hiroshima, Japan On August 6, 1945 at 8:16:02 a.m. Hiroshima time. The bomb, affectionately named "Little Boy," exploded 1,900 feet above the courtyard of Shima Hospital, with a force equivalent to 12,500 tons of TNT. By the end of 1945, 140,00 people had died as a direct result of the bombing. Within the following five years, another 60,000 would die of bomb-related causes.The bomb killed men, women, and children indiscriminately. It killed both military personnel and civilians. Although the city produced military items and housed soldiers, it was not selected as a "purely military target" as President Truman had promised. There were six civilians in Hiroshima to every soldier.The second bomb, called "Fat Man," exploded over Nagasaki, Japan, at 11:02 a.m. on August 9, 1945. It exploded at 1,650 feet with a force of 22,000 tons of TNT. 70,000 people lost their lives in Nagasaki by the end of 1945 due to the bombing. A total of 140,00 died within the next five years.|| Countries that own Nuclear weaponsUnited States · RussiaUnited Kingdom · FranceChina · India · IsraelPakistan · North KoreaSouth Africa|
