Graph of nuclear testing by year and country. From the first nuclear test in 1945, worldwide nuclear testing increased rapidly until the 1970s, when it peaked. [24] However, there was still a large amount of worldwide nuclear testing until the end of the Cold War in the early 1990s. [24]
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Excitation function (a.k.a. yield curve) is a term used in nuclear physics to describe a graphical plot of the yield of a radionuclide or reaction channel as a function of the bombarding projectile energy or the calculated excitation energy of the compound nucleus. [1] The yield is the measured intensity of a particular transition. [2]
Weapons variable yield and weight have been plotted at their highest yield and weight. Also indicated on the graph are a few characteristics of the weapons (Little Boy and Fat Man, the early H-bombs, small tactical weapons, and weapons in the enduring stockpile separated by missile warheads and air-dropped bombs).
Nuclear weapons testing did not produce scenarios like nuclear winter as a result of a scenario of a concentrated number of nuclear explosions in a nuclear holocaust, but the thousands of tests, hundreds being atmospheric, did nevertheless produce a global fallout that peaked in 1963 (the bomb pulse), reaching levels of about 0.15 mSv per year ...
The graph of dose rate as a function of time for the bomb fallout was created using a method similar to that of T. Imanaka, S. Fukutani, M. Yamamoto, A. Sakaguchi and M. Hoshi, J. Radiation Research, 2006, 47, Suppl A121-A127. The graph exhibits the same shape as that obtained in the paper.
On this day in 1957, the first underground nuclear test was carried out at the Nevada Test Site, a 1,375 square-mile research center located 65 miles away from Las Vegas.The 1,7 kiloton nuclear ...
Total country yield is 36.3% of all nuclear testing. ^ Includes all tests with potential for nuclear fission or fusion explosion, including combat use, singleton tests, salvo tests, zero yield fails, safety experiments, and bombs incapacitated by accidents but still intended to be fired.
