The history of radiological explosions began nuclear tests in the middle of the twentieth century, when the first nuclear bomb experiments were in 1945. At that time, the United States detonated two bombs in Hiroshima and Nagasaki, which sparked great controversy over the use of these deadly weapons. Since then, the nuclear forces have continued to develop their technologies and improve their ability to manufacture. Historical effects of nuclear use using nuclear weapons radically changed history. It led to the change of war strategies, and increased the level of political tensions between countries. The new understanding of the nuclear force changed defense policies and contributed to the formation of international alliances. Its effects on humanity are still painful, with long -term effects on the environment and human health.
