local fallout

基本解釋

The fission products are generally dispersed over a large area of the globe unless there is local rainfall resulting in localized fallout.
裂變的產(chǎn)物通常將散布在地球表面一片巨大的區(qū)域上，除非因為下雨產(chǎn)生局部核塵降。
In contrast with air bursts, local fallout can be a hazard over a much larger downwind area than that which is affected by blast and thermal radiation.
和空中爆炸相比，受局部核塵降影響的順風區(qū)域要比沖擊波和熱輻射的影響區(qū)域大的多。
Initial nuclear radiation will be a significant hazard with smaller weapons, but the fallout hazard can be ignored as there is essentially no local fallout from an air burst.
相比小型武器，早期核輻射的危害是很嚴重的。但是放射性塵降的危害可被忽略，因為空中爆炸基本上不會給地面帶來塵降。
