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.
