RDS-37 was the Soviet Union's first two-stage hydrogen bomb, first tested on November 22, 1955. The weapon had a nominal yield of approximately 3 megatons. It was scaled down to 1.6 megatons for the live test. It was a multi-stage thermonuclear device which utilized radiation implosion called Sakharov's ''Third Idea'' in the USSR (the ''Teller–Ulam design'' in the USA). It utilized a fissile core containing Uranium-235 and synthetic Uranium-233,〔(【引用サイトリンク】title=Thorium and its role in the nuclear fuel cycle ) PDF page 8, citing: D. Holloway, “Soviet Thermonuclear Development”, International Security 4:3 (1979–80) 192–197.〕 and a dry lithium deuteride fusion fuel, with some of it replaced with a "passive material" to reduce its total yield. Despite this reduction in yield, because the weapon exploded under an inversion layer much of its shock wave was focused back downward at the ground unexpectedly, causing a trench to collapse on a group of soldiers, killing one, and a building in Kurchatov, distant, to collapse and kill a young girl. It was air-dropped at Semipalatinsk Test Site, Kazakhstan, making it the first air-dropped two-stage thermonuclear test. The ''RDS-6s'' device (Joe-4) exploded in 1953 had one-stage design, and was not scalable into the megaton yield range. Video footages of the ''RDS-37'' are often confused with video footages of the Tsar Bomba, although they can be quite similar. RDS-37 footage have the explosion moved to the center, and Tsar Bomba footage have the explosion moved to the right (except for the mushroom cloud footage, which is in the center). In addition, the ''RDS-37'' test occurred in the Semipalatinsk test area, and some of the footage looks across the roofs of the secret city of Kurchatov, aka Semipalatinsk-16. The ''Tsar'' occurred over the Arctic polar desert island of Novaya Zemlya, with no similar population centers within hundreds of kilometers at that time. ==See also== * RDS-1 * Soviet atomic bomb project *RDS-2 *RDS-3 *RDS-4 *RDS-5 *RDS-37 *RDS-220 * Ivy Mike (first US hydrogen bomb) * Castle Bravo (first US staged dry-fuel design) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RDS-37」の詳細全文を読む スポンサード リンク
