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.
