Decision to create the Semipalatinsk nuclear test was made of the CC CPSU and USSR CM August 21, 1947. Work in preparation for testing at the landfill were completed in July 1949. Successful testing of the first Soviet atomic bomb took place on Aug. 29, 1949 at 7.00 am. Hundreds of thousands of people regularly watched a horrible sight - a huge "mushroom cloud" in the sky ...
During the period from 1949 to 1989 at the site produced 456 nuclear tests (616 nuclear explosions - in one test often blew two or three of the munition at a time). The greatest number of tests were in the early 60's. From 1949 to 1962 there was held on 30 ground-based explosions, 88 nuclear devices were tested in the air, among them the first thermonuclear device (08/12/1953) and the world's first hydrogen bomb (22.11.1955),
6 devices were tested at high altitudes and in space. 18.10.1951 passed the test with a drop atomic bombs from aircraft. In addition to terrestrial explosions at the site produced more than 340 underground tests in vertical wells and horizontal tunnels. Of these, 7 explosions for industrial purposes. The industry's first explosion in a borehole in order to create an artificial pond made at the confluence of Shagan and Aschisu January 15, 1965. Number exploded nuclear weapons is still a mystery.
Former SIYAP located in north-eastern part of Kazakhstan's steppe and semi-arid zone and has a total area of 18,500 sq.km.

destroyed the last tunnel for nuclear testing.Affected by nuclear tests declared 1323000 people, but the identity of victims have received only 1057000 people. So many witnesses can not get the status of victims of the complexity of the procedure. Modern radiation exposure from environmental contamination at the landfill site slightly higher than natural background, but the cumulative lifetime cumulative dose for many people living in the vicinity of the landfill, rather large.
To get on the world's largest landfill does not need special permission! You just get in your car and drive. Not even clear on the range you or beyond. Territory is not marked. No plaques about the dangers.
The landfill is not protected, the population has free access to its territory and even at the epicenter of ground nuclear explosions. Traces of cattle. Unauthorized business activity at the site creates a high likelihood of secondary transfer of radioactivity. Enterprising prospectors in search of scrap penetrate even sealed with concrete plugs gallery. Some of them die there...
