On August 6, 1945, the United States dropped an atomic bomb on the Japanese city of Hiroshima. The explosion destroyed much of the city and killed tens of thousands of people. Three days later, the U.S. dropped another atomic bomb on the city of Nagasaki. These were the only two times in history that nuclear weapons have been used in war.
The effects of the Hiroshima bomb were much more severe than the Nagasaki bomb. This is because the Hiroshima bomb was a more powerful weapon and because the city was closer to the explosion. The Nagasaki bomb was also less effective because the city was surrounded by hills, which protected some of the buildings and people.
The United States decided to drop the atomic bombs on Japan because they wanted to end the war quickly. They also wanted to show the world the power of these new weapons.
The atomic bombings of Hiroshima and Nagasaki were terrible events. But they were not the only times that people have been killed with nuclear weapons.
In 1954, the United States tested a nuclear weapon in the Pacific Ocean. The test sent radioactive fallout across the world. Some of the fallout landed on the island of Rongelap. The people who lived there did not know about the radiation and they ate food that was contaminated with it. Many people died and others got sick.
In 1986, a nuclear power plant in Chernobyl, Ukraine, exploded. The explosion released radioactive material into the air. The material spread across Europe and caused many people to get sick. Some of the people who were exposed to the radiation later died.
