The process of the descent to the earth's surface of particles contaminated with radioactive material from a radioactive cloud. The term is also applied in a collective sense to the contaminated particulate matter itself. The early (or local) fallout is defined, somewhat arbitrarily, as those particles which reach the earth within 24 hours after a nuclear explosion. The delayed (or worldwide) fallout consists of the smaller particles which ascend into the upper troposphere and stratosphere, to be carried by winds to all parts of the earth. The delayed fallout is brought to earth, mainly by rain and snow, over extended periods ranging from months to years.

Radioactive material that falls from the sky after a nuclear accident contaminating the environment, including crops and water supplies.

A general term for debris that falls to the earth from an eruption cloud.

See cross contamination.

any debris ejected from a pyrotechnic effect

Radioactive debris that falls to earth after a nuclear explosion.

Fallout describes how particles that are held in the air descend to the ground and accumulate on surfaces. Fallout is generally associated with particles that have been sent into the atmosphere following a nuclear explosion or a volcanic eruption and slowly descend, falling onto ground or water surfaces.

The transfer to earth of radioactive particles present in the atmosphere as a result of nuclear weapons tests and other nuclear events.

The descent to earth and deposition on the ground of particulate matter (that might be radioactive) from the atmosphere.

fragmental material ejected from a volcano and deposited on the ground; includes everything from blocks near the volcano to fine ash at great distances downwind.

Radioactive materials that are released into the earth's atmosphere following a nuclear explosion or atmospheric release and eventually fall to earth.

composed of the debris from a nuclear explosion. Buildings, trees, or people are pulverized in the blast, this debris is drawn up into the earth's atmosphere. As it rises, fallout is bathed in radiation from the explosion. Picked up by air currents and carried around the earth, fallout can remain in the atmosphere form months or years. It returns to the earth either under its own weight or in rain or snow. Fallout may be intensely radioactive and can cause nausea, hair loss, internal bleeding, genetic damage, and cancer. Fallout is a particularly devastating effect of a nuclear explosion. Fallout created in an all-out nuclear war could cause millions of deaths and contaminate the earth's food and water supply.

The transfer of radionuclides produced by nuclear weapons from the atmosphere to earth; the material transferred.

Fallout is a series of computer role-playing games produced and published by Interplay. Although set in and after the 22nd century, its story and artwork are heavily influenced by the post-World War II nuclear paranoia of the 1950s. The series is sometimes considered to be an unofficial sequel to Wasteland, but it could not use that title as Electronic Arts held the rights to it, and, except for minor references, the games are set in separate universes.

Fallout is a RTÉ two-part fictional drama, made in the style of a documentary. It deals with the nuclear fallout following a hypothetical disaster in the Sellafield Nuclear Reprocessing Plant in Cumbria on the British coast of the Irish Sea. The show suggests that Ireland would bear the brunt of the United Kingdom's accident.
