The immediate objective will be to exploit the available in-~ formation from REDWING. Combining the knowledge of ficsion energy released with the data on local fallout at REDWING it may be possible to estimate the amount of radioactive debris in the stratosphere and hence the amount of world-wide fallout to be anticipated. The next objective will be to apply REDKING and CASTLE data, plua the existing model, to the planning for the next test series with two purposes in Mind; First, to refine the model still more; and second, to apply it directly to the practical problem of minimizing world-wide fallout. The AEC Commisaioners are cesirous of another fallout briefing when the above data and related information on 2ELYING fallout has been further developed to make such a briefing worthwhile. Till you please advise how much of the above information can be obtained and a tentative date that it could te presented to the Commissiony also, what are the possibilities of a more ecmprehensive fallout study for Operation *ILGSIM te further develop the theory er a medel as referred to above?
