About International Day against Nuclear Tests

First nuclear test was conducted on 16 July 1945. After that there was nearly 2000 more nuclear tests have taken place. The tests cause human life, living creatures and atmosphere badly. Hindsight and history have shown us the terrifying and tragic effects of nuclear weapons testing, especially when controlled conditions go awry.

On 2 December 2009, the 64th session of the United Nations General Assembly declared 29 August the International Day against Nuclear Tests by unanimously adopting resolution 64/35. The resolution calls for increasing awareness and education “about the effects of nuclear weapons test explosions or any other nuclear explosions and the need for their cessation as one of the means of achieving the goal of a nuclear-weapon free world”. First observance of the day was made on 29 August 2010.

The date August 29 was selected with a view to commemorate the closure of the Semipalatinsk Nuclear Test site on 29 August 1991.
