Graphic display shows hypothetical, computer-modeled zones of damage, injury, and radiation levels after 10kT ground burst of an improvised nuclear device
Linear scale of miles on both the x and y-axis
Zones are approximate and would likely change over time during an event
Irregular darker blue areas on the right half of the diagram reflect areas of potential radioactive fallout
Note that weather and wind affect where fallout goes over time
Upper winds carry fallout in one direction.
Winds nearer to the earth's surface carry fallout in another direction
This difference is frequently seen, even with normal weather patterns
Both upper and lower winds can change direction normally, and during an event
