Astana (Itar-Tass): Kazakhstan, where 456 atomic tests were conducted over 40 years ago, on Monday marked the International Day against Nuclear Tests.

The UN General Assembly established this day at the suggestion of Kazakh President Nursultan Nazarbayev.

Twenty years ago on this day, the Semipalatinsk nuclear test site was closed by a decree of the Kazakh President. This day is a special day in the history of the republic, as it is connected with the start of the test site activity.

The first nuclear test was conducted on August 29, 1949, and the last one on October 19, 1989.

No major events are planned in the region on this day, sources from the press service of the East-Kazakhstan region said. The region gets ready for the main event in October – an international anti-nuclear forum.

A total of 456 nuclear tests were conducted in Semipalatinsk 40 years ago. The total capacity was 2,500 times higher than the capacity of the atomic bomb dropped on Hiroshima.
