Harry Daghlian
Haroutune Krikor Daghlian Jr. (May 4, 1921 – September 15, 1945) was an American physicist with the Manhattan Project, which designed and produced the atomic bombs that were used in World War II. He accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site of the Los Alamos Laboratory in New Mexico and died 25 days later from the resultant radiation poisoning. Daghlian was irradiated as a result of a criticality accident that occurred when he accidentally dropped a tungsten carbide brick onto a 6.2 kg bomb core made of plutonium–gallium alloy. This core, subsequently nicknamed the " demon core", was later involved in the death of another physicist, Louis Slotin. Early life and education Haroutune Krikor Daghlian Jr., was born in Waterbury, Connecticut, on May 4, 1921, one of three children of Margaret Rose (''née'' Currie) and Haroutune Krikor Daghlian. His father was an ethnic Armenian from Gaziantep in wha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radiation Poisoning
Acute radiation syndrome (ARS), also known as radiation sickness or radiation poisoning, is a collection of health effects that are caused by being exposed to high amounts of ionizing radiation in a short period of time. Symptoms can start within an hour of exposure, and can last for several months. Early symptoms are usually nausea, vomiting and loss of appetite. In the following hours or weeks, initial symptoms may appear to improve, before the development of additional symptoms, after which either recovery or death follows. ARS involves a total dose of greater than 0.7 Gy (70 rad), that generally occurs from a source outside the body, delivered within a few minutes. Sources of such radiation can occur accidentally or intentionally. They may involve nuclear reactors, cyclotrons, certain devices used in cancer therapy, nuclear weapons, or radiological weapons. It is generally divided into three types: bone marrow, gastrointestinal, and neurovascular syndrome, with bone m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gaziantep
Gaziantep, historically Aintab and still informally called Antep, is a major city in south-central Turkey. It is the capital of the Gaziantep Province, in the westernmost part of Turkey's Southeastern Anatolia Region and partially in the Mediterranean Region. It is located approximately east of Adana and north of Aleppo, Syria and situated on the Sajur River. The city is thought to be located on the site of ancient Antiochia ad Taurum and is near ancient Zeugma. Sometime after the Byzantine-ruled city came under the Seljuk Empire, the region was administered by Armenian warlords. In 1098, it became part of the County of Edessa, a Crusader state, though it continued to be administered by Armenians, such as Kogh Vasil. Aintab rose to prominence in the 14th century as the fortress became a settlement, hotly contested by the Mamluk Sultanate, Dulkadirids, and the Ilkhanate. It was besieged by Timur in 1400 and the Aq Qoyunlu in 1420. The Dulkadirid-controlled city fel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birth Name
The birth name is the name of the person given upon their birth. The term may be applied to the surname, the given name or to the entire name. Where births are required to be officially registered, the entire name entered onto a births register or birth certificate may by that fact alone become the person's legal name. The assumption in the Western world is often that the name from birth (or perhaps from baptism or ''brit milah'') will persist to adulthood in the normal course of affairs—either throughout life or until marriage. Some possible changes concern middle names, diminutive forms, changes relating to parental status (due to one's parents' divorce or adoption by different parents), and changes related to gender transition. Matters are very different in some cultures in which a birth name is for childhood only, rather than for life. Maiden and married names The terms née (feminine) and né (masculine; both pronounced ; ), Glossary of French expressions in Englis ...

Louis Slotin
Louis Alexander Slotin ( ; 1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who took part in the Manhattan Project. Born and raised in the North End of Winnipeg, Manitoba, Slotin earned both his Bachelor of Science and Master of Science degrees from the University of Manitoba, before obtaining his doctorate in physical chemistry at King's College London in 1936. Afterwards, he joined the University of Chicago as a research associate to help design a cyclotron. In 1942, Slotin was invited to participate in the Manhattan Project, and subsequently performed experiments with uranium and plutonium cores to determine their critical mass values. After World War II, he continued his research at Los Alamos National Laboratory in New Mexico. On 21 May 1946, he accidentally triggered a fission reaction, which released a burst of hard radiation. He was rushed to the hospital and died nine days later on 30 May. Slotin had become the second fatal victim of a crit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demon Core
The demon core was a sphere of plutonium that was involved in two fatal radiation accidents when scientists tested it as a fissile core of an early atomic bomb. It was manufactured in 1945 by the Manhattan Project, the U.S. nuclear weapon development effort during World War II. It was a subcritical mass that weighed and was in diameter. The core was prepared for shipment to the Pacific Theater as part of the third nuclear weapon to be dropped on Japan, but when Japan surrendered, the core was retained for testing and potential later use in the case of another conflict. The two criticality accidents occurred at the Los Alamos Laboratory in New Mexico on August 21, 1945, and May 21, 1946. In both cases, an experiment was intended to demonstrate how close the core was to criticality, using a neutron-reflective tamper (layer of dense material surrounding the fissile material). In both accidents, the core was accidentally put into a critical configuration. Physicists Harry ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
