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.
裂變的産物通常將散佈在地球表麪一片巨大的區(qū)域上，除非因爲(wèi)下雨産生侷部核塵降。
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，受侷部核塵降影響的順風(fēng)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(yán)重的。但是放射性塵降的危害可被忽略，因爲(wèi)空中爆炸基本上不會(huì)給地麪?zhēng)?lái)塵降。
