International Day against Nuclear Tests – August 29, 2024

International Day against Nuclear Tests is an annual observance on August 29. The day was established by the United Nations General Assembly at their 64th session on December 2, 2009. Nearly 2000 nuclear weapons tests have taken place since the first one on July 16, 1945. The side effects and dangers of nuclear energy testing to human life were dismissed in the early days, but the magnitude of its destructive nature has been proven time and time again in history. Nuclear weapons are volatile and the world can do without it.

History of International Day against Nuclear Tests

At the 64th session of the United Nations General Assembly on December 2, 2009, the unanimous adoption of resolution 64/35 declared August 29 as the International Day Against Nuclear Tests. The crux of the resolution was that “every effort should be made to end nuclear tests in order to avert devastating and harmful effects on the lives and health of people” and that “the end of nuclear tests is one of the key means of achieving the goal of a nuclear-weapon-free world.”

The initiation for this day was by the Republic of Kazakhstan, selecting August 29 as the date of the observance to align with the shut down of the Semipalatinsk Nuclear Test site on the same date in 1991.

The inaugural observance of the International Day Against Nuclear Tests was in 2010. Every year, massive efforts go into arranging activities across the world; including conferences, symposia, competitions, publications, media broadcasts, lectures, and more. Many sponsors, government-level agencies, and civil society organizations have aided the cause and campaigned for the complete ban on nuclear testing.

Why International Day against Nuclear Tests is Important

  1. It emphasizes the dangers of Nuclear testings

    Throughout history, nuclear testing has been exposing communities to nuclear radiation and radioactivity, the results of which have been disastrous.

  2. Moving towards better sustainable energy

    Nuclear energy isn't limited to bombs. Nuclear power plants are a source of energy in some countries around the world, and the volatility of nuclear energy needs to be seriously considered so a shift is made to sustainable sources of generating power.

  3. For a better tomorrow

    A world without nuclear power is utopian, and will definitely lead to better dialogue between countries instead of depending on warfare.
