The energies of the hard betas from Shots 1, 3, and 4 are listed in Table 5.13, The values for the maximm beta energy are nearly constant and approximate 2 Mev, The hard beta energy for sample 1-251.03 at later times appeared to be somewhat high compared to the samples frog other shots, The beta-gamma ratio is 2 for most of the aluminum absorp~ tion curves although for Shot 3 at + 10.3 days the value was one and for one sample from Shot 4 at + 11.1 hr it was three, TABLE 5.13 - Preliminary Summary of Beta Mnergies | Shot L Sample (Time after Burst Max.
