Between. 5 and SO » there was relstive fract onation of these fission products with the exception of Mo?? and C Determination of the relative amounts of Ca(OH)2 and Cac03 in the samples gave inconclusive results, The relative concentration of Sr89 and BallO in Shot & fallout increased with time of collection, ° There was falloutof both radioactive solid and radioactive liquid fromShots 1 and 3, 9 and BalO displayed a greater tendency to concentrate in the liquid phase than the other fission products studied. Shot fallout was almost entirely liquid, ee 46 SECRET — RESTRICTED DATA Py Na alll 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,
