TABLE B.24 COMPUTED BETA-DECAY RATES Beta-emlission rates for flssion products (FP) and Induced products (IP) are computed and summed for the total emission rate In units of (8/sec)/104 fissiona. ‘Product/fission ratios are listed directly under the nuclide symbol. Conversion to counting rates, (counts/sec)/10* fissions, for a weightless mount and (point) source 1s made in the last column by means of the shelf factor G, for comparison with experimental results (Table B.25). Numbers in parentheses indicate the number of zeros between the decimal point and the first significant figure, e.g., (21200 = 0 00200. oot “7 Age Sz Shot Na’4 hr 0.00145 Flathead, Average 45.8 1.12 1.64 2.40 3.52 min hrs hrs hrs hrs 0.763 1.12 1.64 2.40 3.52 5.16 7.56 1L.t 16.2 23.8 hrs hrs hes hrs brs 1.45 2.13 3.12 4.57 6.70 days days days days days 9.82 14.4 21.1 30.9 45.9 days days days days days 66.4 days 97.3 143° 208 301 days days «days days Co® 0.0036 Co® + 0.0053 Cu" + 0.00217 Fallout Composition: ; , counts/sec ' ;10° fissions (G, = 0.2628) \ \ (3)178 (3)174 (3)169 (3)163 (3)153 1.544 ‘1.009 0.634 0.398 0.255 10.5274 0.3324 0.1969 0.1166 (1)7335 (3)146 (3)131 (3)111 (4)880 (4)618 (6)754 (6)754 (6)752 (6)751 (6)748 (3)140 (3)123 (3)102 (4)773 (4)513 0.166 0.109 1 (1)716 | (1)456 (1)282 (1)4893 (1)3364 (1)2343 (1)1615 (1)1103 34.8 51.1 14.9 109.7 160.8 (4)376 (4)175 {5)590 (5)119 (6)112 (6)745 (6)740 (6)733 (6)723 (6)708 (4)283 (4)117 (5)327 (6)498 (7)315 (1)176 (1)109 (2)674 (2)452 (2)309 (2)7640 (2)5256 (2)3564 (2)2430 (2)1580 235.7 345.6 506.4 741.6 1,087 (8)344 (10)230 (6)688 (6)658 (6)617 (6)561 (6)489 (9)566 (11)141 1,594 2,335 3,432 4,992 7,224 Nog Fp (6)756 (6)756 (6)755 (6)755 (6)754 5.16 7.56 1h 16.2 23.8 (3)180 (3)177 (3)173 (3)167 (3)158 Sum a \ (6)398 (6)296 (G)L91 (6)102 (7)417 ' | (2)212 (2)145 (3)972 | (3)637 (3)411 | (3)262 (3)170 (3)105 (4)590 (4)311 (3)9708 (3)5770 , (3)3374 (3)1957 (3)1145 4)6968 4478 )2765 (4)1553 (48184
