NUCLEAR-DEBRIS FORMATION
EQUIVALENT FISSIONS
41
The number of equivalent fissions present in
a sample as determined by analysis for any constituent is the prod-
uct of the total number of fissions produced by the device and the
fraction of the total amount of constituent present (replaces the
“fissions in the sample” concept).
FRACTIONATION COEFFICIENT OF TWO CONSTITUENTS IN A SAMPLE The ratio of their fractions or equivalent fissions.
*THE FRACTIONATION RATIO The ratio of fractions or equivalent
fissions of *Sr to ®Zr.
*DEGREE OF FRACTIONATION
tionation ratio.
*TERACALORIE
The Briggsian logarithm of the frac-
10calories (the kiloton equivalent of energy).
*TERACALORIE EQUIVALENT OF A NUCLIDE
The ratio of quantity
of nuclide produced in a detonation to the energy release in teracalories by fission.
TERACALORIE EQUIVALENT PER SQUARE MILE
unit of con-
tamination surface density (replaces the “kilotons per Square mile”
concept).
