Is there still nuclear radiation in Hiroshima and Nagasaki, Japan?

The level of nuclear radiation in Hiroshima and Nagasaki has been greatly reduced, but there are still some residual radioactive materials.

Hiroshima and Nagasaki suffered nuclear explosions in 1945, which led to large-scale radiation release and extensive damage. As time goes by, the radiation level gradually decreases, but the existence of radioactive substances can still be detected in some places. However, these radiation levels have been reduced to a level that will not directly affect human health. The Japanese government has been taking measures to monitor and manage radiation levels to ensure public safety.

The source of nuclear radiation in Hiroshima and Nagasaki is the nuclear radiation produced by the atomic bomb explosion. 1945, the United States carried out atomic bomb attacks on these two cities during World War II. These nuclear explosions caused huge explosions and fires, releasing a lot of nuclear radiation. The radiation produced by nuclear explosion includes electromagnetic radiation and the release of radioactive substances, which has caused serious damage and casualties, and caused long-term health problems.

Consequences of a nuclear explosion

Explosion and shock wave: A nuclear explosion will cause a violent explosion, produce a powerful shock wave, instantly destroy buildings and infrastructure, and cause extensive damage and casualties. Fire: After the nuclear explosion, a large number of flames and fireballs will burn the surrounding buildings and trees, forming a large-scale fire, further aggravating the damage and causing more casualties.

Radioactive radiation: Radioactive substances released by nuclear explosions will cause radiation pollution, and people who have been exposed to radiation for a long time may suffer long-term health effects. Nuclear winter: the huge energy released by nuclear explosion will produce huge fireballs and mushroom clouds, and cause a lot of dust generated by fires and ruins. These dust and smoke will enter the atmosphere, preventing sunlight from reaching the earth, resulting in a sharp drop in temperature and a cold climate. It is called nuclear winter, which may have a long-term impact on the global environment and crops.
