A transparent plastic map overlay on which is printed a graduated azimuth circle(s) with semicircles representing the stabilized nuclear cloud radii of various kiloton detonations, scaled downwind distance lines angled from ground zero, and a downwind distance nomogram. The predictor is intended for use in making rapid estimates of the downwind area threatened by radioactive fallout from a nuclear burst. View more Radiological Fallout Area Predictor
