 (later renamed Semey), near the border of East Kazakhstan Province and Pavlodar Province with most of the nuclear tests taking place at various sites further to the west and south, some as far as into Karagandy Province.

The 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.

History

The site was selected in 1947 by Lavrentiy Beria

The first Soviet bomb test, Operation First Lightning (nicknamed Joe One by the Americans) was conducted in 1949 from a tower at the Semipalatinsk Test Site, scattering fallout

 on nearby villages (which Beria had neglected to evacuate). The same area ("the experimental field", a region forty miles west of Kurchatov city) was used for more than 100 subsequent above-ground weapons tests.

Later tests were moved to the Chagan River complex and nearby Balapan in the east of the STS (including the site of the Chagan test

, which formed Chagan Lake). Once atmospheric tests were banned, testing was transferred to underground locations at Chagan, Murzhik (in the west), and at the Degelen Mountain complex in the south, which is riddled with boreholes and drifts for both subcritical and supercritical tests. After the closure of the Semipalatinsk labour camp, construction duties were performed by the 217th separate engineering and mining battalion (who later built the Baikonur Cosmodrome

). Between 1949 and the cessation of atomic testing in 1989, 456 explosions were conducted at the STS, including 340 underground (borehole and tunnel) shots and 116 atmospheric (either air-drop or tower shots). The lab complex, still the administrative and scientific centre of the STS, was renamed Kurchatov

This smaller research station, known to the Department of Defense as PNUTS (Possible Nuclear Underground Test Site) and the CIA as URDF-3 (Unidentified Research and Development Facility-3) was "studied" by remote viewers during project Stargate. After the fall of the Soviet Union in 1991, it was discovered that the mysterious URDF-3 was tasked with researching nuclear powered spaceships similar to the US's Project Orion

The site was officially closed on 29 August 1991.

, Nevada-Semipalatinsk played a positive role in promoting public understanding of "the necessity to fight against nuclear threats". The movement gained global support and became "a real historical factor in finding solutions to global ecological problems".

Health impacts

The full impact of radiation exposure was hidden for many years by Soviet authorities. The general consensus of health studies conducted at the site since it was closed is that radioactive fallout from nuclear testing had a direct impact on the health of about 200,000 local residents. Specifically, scientists have linked higher rates of different types of cancer to post-irradiation effects. Likewise, several studies have explored the correlation between radiation exposure and thyroid abnormalities.
