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,
