  Semipalatinsk Test Site - Wikipedia, the free encyclopedia
The Semipalatinsk Test Site (STS) was the primary testing venue for the Soviet Union's nuclear weapons.
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 Lake Chagan).
Semipalatinsk was the site that Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan chose for the signing of the Central Asian Nuclear Weapon Free Zone on September 8, 2006, also commemorating the 15th anniversary of the test site's closing.

The objectives were to collect additional radiological data from in and around the site, collect and review existing data provided by Russian and Kazakh sources relevant to the radiological situation at the test site, and to perform a preliminary assessment of the present and potential future doses to residents in the Semipalatinsk area.

 NATO Review - Vol. 49 - No 3 - Autumn 2001
Between 1949 and 1989, a total of 456 nuclear tests were carried out at Semipalatinsk in Kazakhstan, the former Soviet Union's premier test site, before its closure by presidential edict in 1991.
The Semipalatinsk project, which is a joint venture between scientists from Kazakhstan and the United Kingdom, aims to examine contamination levels across some 600 square kilometres of the 22,000 square kilometre site, an area about the size of Wales.
The Semipalatinsk project seeks to measure contamination levels throughout the 600 square kilometre area, identifying land that is immediately fit for human settlement, land which could be settled with minimal clean-up work, and land which should permanently be placed off limits to humans.

 NATO Update: Radioactive contamination in Kazakhstan - 14 January 2002
A NATO "Science for Peace" study of the radioactive contamination at the former Soviet nuclear test site in Semipalatinsk, Kazakhstan, was presented to a Technical Meeting of the International Atomic Energy Agency (IAEA) held in Vienna on 14-18 January.
After closure of the test site in 1991, information on the radioactive contamination was classified and controlled by military departments until 1993, when the first international experts were allowed access to the site.
There are indications that the area selected for the NATO study was used for grazing by domestic animals before the creation of the test site and it is hoped that one of the outcomes of the study will be the reclamation of the contaminated steppe lands for safe grazing once more.

 IREX | 2002 Caspian Sea Regional Policy Symposium
The test site is surrounded by several villages and located approximately 150 km west of the city of Semei (formerly Semipalatinsk).
Before most tests, villagers were usually warned that there would be an "explosion" but they were neither told the reason for the explosion nor warned of the potential health risk.
Although the majority of radionuclides are significantly decayed within thirty days of a nuclear test, a few radionuclides (such as plutonium) have extremely long half-lives, and thus the average exposure to radiation continues to be slightly higher than background radiation would otherwise be in the areas near the test site.
