A sharp increase in the ratio of strontium-89 to strontium-90 in rain was observed at Fayetteville, Arkansas, after the French nuclear detonations of February and April 1960. Experimental data obtained suggest the possibility that part of the debris from atom bombs detonated in the tropical region may enter the stratosphere.
1960年2月和4月法国进行核爆炸后，在阿肯色州费耶特维尔观测到雨中锶 - 89与锶 - 90的比例急剧上升。所获得的实验数据表明，在热带地区引爆的原子弹碎片有可能部分进入平流层。
