The Soviet Union detonated its first atomic bomb, known in the West as Joe-1, on Aug. 29, 1949, at Semipalatinsk Test Site, in Kazakhstan.
How did the USSR develop an atomic bomb in 1949?
The Soviets started experimenting with nuclear technology in 1943, and first tested a nuclear weapon in August 1949. Many of the fission based devices left behind radioactive isotopes which have contaminated air, water and soil in the areas immediately surrounding, downwind and downstream of the blast site.
Who exploded their own atomic bomb in 1949?
the Soviet Union
On 29 August 1949, the Soviet Union conducted its first nuclear test, code-named ‘RDS-1’, at the Semipalatinsk test site in modern-day Kazakhstan. The device had a yield of 22 kilotons.
What was the Soviet version of NATO called?
The Warsaw Pact
The Warsaw Pact was a collective defence treaty established by the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe: Albania, Bulgaria, Czechoslovakia, East Germany, Hungary, Poland and Romania (Albania withdrew in 1968).
What was the nickname of the first atomic bomb detonated by the Soviet Union?

What was the reaction to the Soviet bomb?
The Soviet detonation of the A-Bomb caused something like a panic in America. Many Americans built nuclear air raid shelters and made plans to survive a nuclear war. Three months later, Klaus Fuchs, a German-born physicist who had worked on the Manhattan Project was arrested.
Who was involved in the Soviet atomic bomb project?
In 1940–42, Georgy Flyorov, a Russian physicist serving as an officer in the Soviet Air Force, noted that despite progress in other areas of physics, the German, British, and American scientists had ceased publishing papers on nuclear science. Clearly, they each had active secret research programs.
What was the name of the first Soviet hydrogen bomb?
RDS-6. RDS-6, the first Soviet test of a hydrogen bomb, took place on August 12, 1953, and was nicknamed Joe 4 by the Americans. It used a layer-cake design of fission and fusion fuels (uranium 235 and lithium-6 deuteride) and produced a yield of 400 kilotons.
