About International Day Against Nuclear Tests

It was officially proclaimed by United Nations General Assembly (UNGA) by unanimously adopting Resolution 64/35 in December 2009 initiated by Kazakhstan with support of large number of sponsors and cosponsors. It was observed for first time in 2010 and since then observed annually to galvanize necessity of banning nuclear weapon tests.

Why August 29? It seeks to commemorate closure of Semipalatinsk Nuclear Test site (also known as The Polygon) on 29 August 1991. This nuclear test site was the primary testing venue for nuclear weapons of then Soviet Union. It is located on steppe in northeast Kazakhstan (then Kazakh SSR part of USSR), south of valley of the Irtysh River. On this test site, Soviet Union had conducted total 456 nuclear tests from 1949 until 1989 (340 underground and 116 atmospheric explosions i.e. roughly equivalent of 2500 Hiroshima atomic bombs) with little regard for their ill-effects of radiation on local people or environment.
