451% of total beta activity.
515% of total beta activity.
19% of total fission product beta activity.
A review of the data in Table 9 indicated to us that the activity
ratios for L32q6, 1327, 131y, l4ice, 106RuRh, 144cepr (their activity relative
to measured 957 eNb beta activity) did not differibs a factor greater than about
1.5
by
from the unfractionated ratios.
Ratios for 140gara, 147na, %1ly,
0 Ru, and l43pr were different by a factor of about 2 for 895, and 129mpe-l297,
a factor of about 3 relative to the unfractionated ratios.
l CRuRh,
L29mp—-l29 re, 132te,
132y,
The nuclides 9ly,
144cepr, L43pr, and 47nd were in greater
abundance relative to unfractionated debris.
