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 weapon 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.” The resolution was initiated by the Republic of Kazakhstan, together with a large number of sponsors and cosponsors with a view to commemorate the closure of the Semipalatinsk Nuclear Test site on 29 August 1991.
2010 marked the inaugural commemoration of the International Day against Nuclear Tests.
The Day is meant to galvanize the United Nations, Member States, intergovernmental and non-governmental organizations, academic institutions, youth networks and the media to inform, educate and advocate the necessity of banning nuclear weapon tests as a valuable step towards achieving a safer world.
Since nuclear weapons testing began in the mid-twentieth century, with the first test on 16 July 1945, nearly 2,000 have taken place. There has been little consideration of the devastating effects of testing on human life, let alone the understanding of nuclear fallout from atmospheric tests. Early on, having nuclear weapons was a measure of scientific sophistication or military might. Hindsight and history have shown us the terrifying and tragic effects of nuclear weapons testing, especially when controlled conditions go awry, and in light of today’s nuclear weapons which are far more powerful and destructive. Subsequent incidents world-wide have provided compelling reasons for the need to observe the International Day against Nuclear Tests - a day in which educational events, activities and messages aim to capture the world’s attention and underscore the need for a unified attempt in preventing further nuclear weapons testing.
