The International Day against Nuclear Tests is observed on August 29. It was established on December 2, 2009 at the 64th session of the United Nations General Assembly by the resolution 64/35. Since nuclear weapons testing began in the mid-twentieth century, with the first test on 16 July 1945, nearly 2,000 have taken place. The International Day Against Nuclear Tests aims to raise public awareness about the effects of global nuclear weapon tests, and advocates the banning of nuclear tests as a step to achieving a safer world. To mark this year’s International Day Against Nuclear Tests, an exhibition of art related to nuclear testing and nuclear weapons by artists from Austria, China, Kazakhstan, and the United States was on display at the Vienna International Centre.

Nuclear tests determine the effectiveness and explosive capability of nuclear weapons. Most nations that have developed nuclear weapons have tests of them. Nuclear testing has often been used as presentation of scientific and military strength. There are two types of bombs which release energy from the nuclei of atoms. The simplest kind is an atomic bomb. It releases great quantities of energy through a process called nuclear fission. It is a large unstable (radioactive) element like uranium or plutonium. Another type is the hydrogen bomb, or thermonuclear bomb, which releases an even greater quantity of energy through nuclear fusion.
