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，受局部核尘降影响的顺风区域要比冲击波和热辐射的影响区域大的多。
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，早期核辐射的危害是很严重的。但是放射性尘降的危害可被忽略，因为空中爆炸基本上不会给地面带来尘降。
The fission products are generally dispersed over a large area of the globe unless there is local rainfall resulting in localized fallout.
