Radioactive pollution that is spread through the earth's atmosphere is termed fallout. Such pollution was most common in the two decades following World War II, when the United States, the Soviet Union, and Great Britain conducted hundreds of nuclear weapons tests in the atmosphere. France and China did not begin testing nuclear weapons until the 1960s and continued atmospheric testing even after other nations had agreed to move their tests underground.

Three types of fallout result from nuclear detonations: local, tropospheric, and stratospheric. Local fallout is quite intense but short-lived. Tropospheric fallout (in the lower atmosphere) is deposited at a later time and covers a larger area, depending on meteorological conditions. Stratospheric fallout, which releases extremely fine particles into the upper atmosphere, may continue for years after an explosion and attain a worldwide distribution.

The two best known examples illustrating the effect of fallout contamination are...
