Does Nagasaki still have radiation?

How long was Hiroshima unlivable?





The restoration process took approximately two years and the city’s population, which had dwindled to about eighty thousand after the bombing, doubled in a short time. Until March 1946 the ruins were cleared, and the buildings that were damaged but still standing underwent controlled demolition.

Why is Nagasaki not radioactive?

Neutrons can cause non-radioactive materials to become radioactive when caught by atomic nuclei. However, since the bombs were detonated so far above the ground, there was very little contamination—especially in contrast to nuclear test sites such as those in Nevada.

Where is the most radioactive place on Earth?

Fukushima is the most radioactive place on Earth. A tsunami led to reactors melting at the Fukushima nuclear power plant. Even though it’s been nine years, it doesn’t mean the disaster is behind us. The Japanese government is actually thinking about dumping radioactive water in the Pacific.



How long does radiation last from a nuke?

Some stay in the environment for a long time because they have long half-lives, like cesium-137, which has a half-life of 30.17 years. Some have very short half-lives and decay away in a few minutes or a few days, like iodine-131, which has a half-life of 8 days.

How did the Torii Gate survive?

In 1945, when the atomic blast struck Hiroshima, the Gokoku Shrine was located less that 1 kilometer away from the explosion hypocenter. Because it was so close and the blast came almost vertically, one of the shrine’s 3 torii gates, the one from the main entrance, survived almost undamaged.
