ADDENDUM
For purposes of clarification, the following information (underlined below) is
being added to your copy of UCRL-53152 Part 5:
Each Appendix contains 11 pages of calculated results relating to
one Event in Table 1.
Each set of 11 pages is marked Page 2 through Page
12 at the top and A2 through Al2 (or B2 through B12, etc.) at the
bottom.
Page 2 of each set gives the external gamma-ray exposure rates
and associated values of total microcuries per square meter at 30 decay
intervals and at zero time.
Note that the totals at zero time include
only the nuclides listed in pages 3 through 12, not all the nuclides
present at zero time.
Calculated values for each radionuclide at various
decay intervals are given in the remaining pages--from 1 to 21 hr in
Pages 3-7,
from 1 to 300 d in Pages 8-11, and from 1 to 50 y in Page 12.
Unless otherwise indicated,
the value for each nuclide at zero time is
the result of a radiochemical measurement.
The measurements were
after detonation.
