After a nuclear explosion, debris and soil can mix with radionuclides. This mixture is sent to the air and then falls back to Earth. It's called catarrhal rain, and it usually contains hundreds of different radionuclides. Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses the energy released by the division of atomic nuclei.
When a nuclear device explodes, a large fireball is created. Everything inside this fireball vaporizes, including soil and water, and is carried upwards. This creates the mushroom-shaped cloud that we associate with a nuclear explosion, detonation, or explosion. The radioactive material from the nuclear device mixes with the material vaporized in the cloud in the form of a mushroom.
As this vaporized radioactive material cools, it condenses and forms particles, such as dust. The condensed radioactive material then falls back to the earth; this is what is known as rain. Because rain comes in the form of particles, it can travel long distances in wind currents and end up miles from the explosion site. Rain is radioactive and can cause contamination of anything it falls on, including food and water supplies.
Be inside before the consequences come. The highest levels of outdoor rain radiation occur immediately after the arrival of rain and then decrease over time. While a serious event, such as a plane crash against a nuclear power plant, could result in the release of radioactive material into the air, a nuclear power plant would not explode like a nuclear weapon. Given the effects of a nuclear bomb, it is not surprising that the CND is campaigning against nuclear weapons.
A nuclear explosion, caused by the explosion of a nuclear bomb (sometimes called nuclear detonation), involves the joining or splitting of atoms (called fusion and fission) to produce an intense pulse or wave of heat, light, air pressure, and radiation. A bomb case would produce a very destructive nuclear explosion, but not as large as that of a nuclear weapon developed for strategic military purposes. In the 1980s, scientists evaluated the possible effects of nuclear war (many nuclear bombs explode in different parts of the world) and proposed the theory that a nuclear winter could occur. On the other hand, a nuclear explosion that occurs at or near the Earth's surface can cause serious pollution from radioactive fallout.
