Calculated values for each radionuclide at various decay intervals are given in the remaining pages—from 1 to 21 h on pp. 3-7, from 1 to 300 d on pp. 8-11. and from 1 to 50 v on p. 12. Note that the totals at zero time include only the nuclides decay intervals and at zero time. The value for eachactivation product at zero timeis the result of a measurement. The measurements were per- formed on debris samples taken bvaircraft approximately 1 to 4 h after detonation. When no measurement exists, the value appears as zero. Fission products were calculated from the fissioning nuclides and neutron energy spectra. listed on pp 3-12, not all nuclides present at zero time. References rm 1. 3. 4. H. G.
