CADIZ: I don't think thet could compare uith sampling from the jbtes KELLOGG: Cne thing we've been thinking about a little ie the possibility of sampling, or getting a direct measurement of radicactivity in the stratosphere by a method which would involve sendin | balloons. The edvantage of balloons is that they can get wp, at present, higher than any cperational afroraft that ve pb: I suspect that EXE aince the height of the tropopause in Marshall Islands 18 around 55,000 ft., ve wuld just aboyt have - to have balloons in order to suaple the stratosphere at these = - levels, In fact, if ve can consider the transportany dng like horisontal, then ve would expect to see the debris along at heights from 55,000 ft up anddownwienitreached the et te Mle= ee ee = . middle latitutes. In trying to imagine what balloon sempling would lock like, we have been inquiring about sowe methon of doing it similarly — on a basis siniler to our present katic sonde networks, In the history of upper atacephere research — I can't reneuber back, but I cen read aboutthe grost owtof the early radicsondes — it was HM considered quite a talc! te do it.
