The M5 radiological fallout predictor is a transparent
device used to outline the zones
of hazard resulting from surface bursts for preselected yield groups. The M5
fallout predictor is
composed of two simplified predictors and a nomogram for determining the downwind
of Zone I. One simplified predictor is drawn to a scale of 1: 50,000; the other
predictor is drawn
to a scale of 1: 250,000. Each predictor contains six preselected yield groups
(A, B, C, D, E, and F).
This is used as an overlay for 1:50,000 or 1:250,000
This one is in 8 colors.
Overall dimensions: 40 inches long by 23½
All you need to know to use this is:
Wind speed and direction, location of ground zero
and actual (or estimated with your ABC-M4A1) yield of the nuclear weapon.
This overlay is used for surface or low air burst weapons.
