108 fissions

_counts/sec

Beta-emlasion rates for fission products (FP) and induced products (IP) are computed and summedfor the total emission rate in units of (@/sec)/10* fissions.
‘Product/flgsion ratios are listed directly under the nuclide symbol. Conversion to counting rates, (counts/sec)/10* fissions, for a weightless mount and
(point) source is 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.
