International Day Against Nuclear Tests

International Day Against Nuclear Tests is a serious and significant observance. Its mission is to raise awareness about the devastating consequences of nuclear disasters and emphasize that nuclear testing offers no benefit to modern, civilized societies. The environmental and human costs of such tests are severe and long-lasting. Remaining indifferent to the dangers of nuclear testing is, in essence, agreeing with those who endanger our shared planet.

History

International Day Against Nuclear Tests was established by the United Nations on December 2, 2009, through a unanimously adopted resolution. The date chosen for this important observance is August 29.

Interesting Facts

From 1945 to 1996, over 2,000 nuclear weapons tests were conducted worldwide. More than half were carried out by the United States, with the USSR and the United Kingdom ranking second and third. At first, scientists did not fully grasp the catastrophic consequences of nuclear testing.

Between 1951 and 1973, nuclear tests led to more than a million deaths. Radiation exposure caused severe health problems for people living near test sites, including radiation sickness, birth defects, and high infant mortality. Animals and plants in contaminated areas were also affected, contributing to the spread of radioactive materials. Consuming the milk of infected cows and crops grown in contaminated soil led to new diseases and more deaths.
