... , but unless it is in direct contact with the body, it is of less physiological significance. Alpha activity from unfissioned materials and the radioactivity from neutronactivated products is usually negligible by comparison.

... Close-in fallout consists of solid particles settling to earth under gravity within a few hours after the explosion. It may extend several hundred miles downwind from the site of a large nuclear explosion.

... . This wide range in gross chemical composition, considered along with the observed range of particle sizes, leads to the conclusion that the biological availability of the constituent radioactive isotopes cannot be predicted for a particular material without some knowledge of its characteristics.
