CONCLUSIONS AND RECOMMENDATIONS CONCLUSIONS The activity concentrations of Sr°9, 2495, M099, BstliO, ana collth in the hot fallout particles from Shot 1 collected at How decreased regularly with increasing particle size from 5 to 50 1. The relation ships displayed a discontinuity or inflectionat about 50 yp. Between S and $0 ,: there wag relative fractionation of these fiselion products with the exception of Mo79 and C Determination of the relative amounts of Ca(OH) and Cac03in the samples gave inconclusive results, The relative concentration of Sr89 and BallO in shot k fallout increased with time of collection. There was fallout t3 both redtoactive solid and radioactive liquid from Shots 1 and 3, 9 and Bal O displayed a greater tendency to concentrate in the itewid phese than the other fission products studied. Shot 4 fallout was almost entirely liquid. The base surge sampling program was unsuccessful, The gross decay Shot 1 fallout did not vary with particle size at early time, At later times the gross decay variation with particle size does correlate with the slight trend in radiochemical composition. 46 SECRET —- RESTRICTED DATA : Al A & i CHAPTER 6 6.1 y . - pate? © f «
