   Alternatively you just use the system we used to track the radiation   
   release after the Chernoby disaster and the post war nuclear tests. A   
   simple flight downwind of the target collecting data and samples worked   
   well enough in the 1940's and still does. As someone who was involved   
   in the nuclear industry from 1972 to 1996 I can say the USAAF (and RAF)   
   knew more about this stuff in 1956 than you do in 2022.   
      
   BTW recordation is not a word - recording is but plotting is what you   
   do. If you have GPS you already know the way point locations. The RAF   
   were plotting fallout plumes in Australia after the Nuclear tests that   
   took place between 1952 and 1957.
