General Assembly High-level meeting to commemorate and promote the International Day against Nuclear Tests
26 Aug 2020 -  Since nuclear weapons testing began on 16 July 1945, nearly 2,000 have taken place. In the early days of nuclear testing little consideration was given to its devastating effects on human life, let alone the dangers of nuclear fallout from atmospheric tests. 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 the far more powerful and destructive nuclear weapons that exist today.

2010 marked the inaugural commemoration of the International Day against Nuclear Tests. In each subsequent year, the day has been observed by coordinating various activities throughout the world, such as symposia, conferences, exhibits, competitions, publications, lectures, media broadcasts and other initiatives. 

Since its establishment, many bilateral and multilateral governmental level developments as well as broad movements in civil society have helped to advance the cause of banning nuclear tests.
