Radiation burnA radiation burn is a damage to the skin or other biological tissue and organs as an effect of radiation. The radiation types of greatest concern are thermal radiation, radio frequency energy, ultraviolet light and ionizing radiation. The most common type of radiation burn is a sunburn caused by UV radiation. High exposure to X-rays during diagnostic medical imaging or radiotherapy can also result in radiation burns.
Caesium-137Caesium-137 (), cesium-137 (US), or radiocaesium, is a radioactive isotope of caesium that is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. Trace quantities also originate from spontaneous fission of uranium-238. It is among the most problematic of the short-to-medium-lifetime fission products.
HibakushaHibakusha (çibaꜜkɯ̥ɕa or çibakɯ̥ꜜɕa; 被爆者 or 被曝者; "survivor of the bomb" or "person affected by exposure [to radioactivity]") is a word of Japanese origin generally designating the people affected by the atomic bombings of Hiroshima and Nagasaki at the end of World War II. The word hibakusha is Japanese, originally written in kanji. While the term Hibakusha 被爆者 (hi 被 "affected" + baku 爆 "bomb" + sha 者 "person") has been used before in Japanese to designate any victim of bombs, its worldwide democratization led to a definition concerning the survivors of the atomic bombs dropped in Japan by the United States Army Air Forces on the 6 and 9 August 1945.
Nuclear falloutNuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated.
Bikini AtollBikini Atoll (ˈbɪkᵻˌniː or bᵻˈkiːni; Marshallese: Pikinni, pikinniy, meaning "coconut place"), known as Eschscholtz Atoll between the 1800s and 1946, is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. The Atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. After the Second World War, the atoll was chosen by the United States as a nuclear weapon testing site.
Los Alamos National LaboratoryLos Alamos National Laboratory (often shortened as Los Alamos and LANL) is one of the sixteen research and development laboratories of the United States Department of Energy (DOE), located a short distance northwest of Santa Fe, New Mexico, in the American southwest. Best known for its central role in helping develop the first atomic bomb, LANL is one of the world's largest and most advanced scientific institutions. Los Alamos was established in 1943 as Project Y, a top-secret site for designing nuclear weapons under the Manhattan Project during World War II.
Inertial confinement fusionInertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium (2H) and tritium (3H). Energy is deposited in the target's outer layer, which explodes outward. This produces a reaction force in the form of shock waves that travel through the target. The waves compress and heat it. Sufficiently powerful shock waves generate fusion.
RadiophobiaRadiophobia is a fear of ionizing radiation. Examples include health patients refusing X-rays because they believe the radiation will kill them, such as Steve Jobs and Bob Marley who both died after refusing radiation treatment for their cancer. Given that overdoses of radiation are harmful, even deadly (i.e. radiation-induced cancer, and acute radiation syndrome) it is reasonable to fear high doses of radiation. The term is also used to describe the opposition to the use of nuclear technology (i.e.
HohlraumIn radiation thermodynamics, a hohlraum (a non-specific German word for a "hollow space" or "cavity") is a cavity whose walls are in radiative equilibrium with the radiant energy within the cavity. This idealized cavity can be approximated in practice by making a small perforation in the wall of a hollow container of any opaque material. The radiation escaping through such a perforation will be a good approximation to black-body radiation at the temperature of the interior of the container.
