A review of the data in Table 9 indicated to us that the activity ratios for 13216, 132;, 131, l4lce, 106RuRh, l44cepr (their activity relative to measured 95ZrNb beta activity) did not differ by a factor greater than about 1.5 from the unfractionated ratios. Ratios for 14 BaLa, 147na, 9ly, 90srY, O3Ru, and |43pr were different by a factor of about 2 for 8957 and 129mp_-12%76 by a factor of about 3 relative to the unfractionated ratios. The nuclides 9ly, 106RuRh, 129mpe-1297e, 132¢7¢, 1327, 144cepr, 143pr, and 147Nd were in greater abundance relative to unfractionated debris. - 20 -
