Particle size: Assuming constant wind and altitude, larger particles land relatively close to ground zero and smaller particles land farther away. |
|
Altitude: The higher the initial altitude of a particle, the farther away from ground zero it lands, assuming constant wind speed and particle size. This means that the fallout pattern will be different if there is a ground burst vs. one from an altitude, and increasing altitude will also affect the fallout pattern. |
|
Wind: Wind is the most difficult factor to predict. Different altitudes through which a particle falls may have different wind speeds and directions that affect the final destination of the fallout particle. This explains how fallout can occur miles upwind of a detonation. |
