Semipalatinsk Test Site
The Semipalatinsk Test Site (Russian: Семипалатинск-21; Semipalatinsk-21), also known as "The Polygon", was the primary testing venue for the Soviet Union's nuclear weapons. It is located on the steppe in northeast Kazakhstan (then the former Kazakh SSR), south of the valley of the Irtysh River. The scientific buildings for the test site were located around west of the town of Semipalatinsk (later renamed Semey), near the border of East Kazakhstan Region and Pavlodar Region with most of the nuclear tests taking place at various sites further to the west and south, some as far as into Karagandy Region. The former Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991. According to estimates from Kazakh experts, 1.5 million peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joe 1
The RDS-1 (russian: РДС-1), also known as Izdeliye 501 (device 501) and First Lightning (), was the nuclear bomb used in the Soviet Union's first nuclear weapon test. The United States assigned it the code-name Joe-1, in reference to Joseph Stalin. It was detonated on 29 August 1949 at 7:00 a.m., at the Semipalatinsk Test Site, Kazakh Soviet Socialist Republic, Kazakh SSR, after top-secret research and development as part of the Soviet atomic bomb project. Description The weapon was designed at the Kurchatov Institute, then at the time officially known as "Laboratory № 2" but designated as the "office" or "base" in internal documents, starting in April 1946. Plutonium for the bomb was produced at the industrial complex Mayak, Chelyabinsk-40. The RDS-1 nuclear weapon yield, explosive yield was 22 kilotons TNT equivalent, similar to the US Trinity (nuclear test)#The Gadget, Gadget and Fat Man bombs. At Lavrentiy Beria's insistence, the RDS-1 bomb was designed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Atomic Bomb Project
The Soviet atomic bomb project was the Classified information in Russia, classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was not initiated and prioritized until Operation Barbarossa. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by Germany, German, United States, American, and United Kingdom, British scientists, Russian physicist Georgy Flyorov suspected that the Allies of World War II, Allied powers had secretly been developing a "Weapon of mass destruction, superweapon" since 1939. Flyorov wrote a letter to Stalin urging him to start this program in 1942. Initial efforts were slowed due to the Operation Barbaro ...

Lavrentiy Beria
Lavrentiy Pavlovich Beria (; rus, Лавре́нтий Па́влович Бе́рия, Lavréntiy Pávlovich Bériya, p=ˈbʲerʲiə; ka, ლავრენტი ბერია, tr, ; – 23 December 1953) was a Georgian Bolshevik and Soviet politician, Marshal of the Soviet Union and state security administrator, chief of the Soviet security, and chief of the People's Commissariat for Internal Affairs (NKVD) under Joseph Stalin during the Second World War, and promoted to deputy premier under Stalin in 1941. He officially joined the Politburo in 1946. Beria was the longest-lived and most influential of Stalin's secret police chiefs, wielding his most substantial influence during and after the war. Following the Soviet invasion of Poland in 1939, he was responsible for organizing purges such as the Katyn massacre of 22,000 Polish officers and officials. He would later also orchestrate the forced upheaval of minorities from the Caucasus as head of the NKVD, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David E
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, Dav ...

Plutonium
Plutonium is a radioactive chemical element with the symbol Pu and atomic number 94. It is an actinide metal of silvery-gray appearance that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthetically produced and isolated in late 1940 and early 1941, by a deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 ( half-life 2.1 days) was synthesized, which subsequently beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). ...
