Repeating the procedure described in Steps 4 through 6 above upon receipt of the 1500,
0200, and 1200 measurements, the prediction for R36 is updated to 18.0, 14.5, and 12.5
See Figure 6-8 on page 6-20 for an illustration of the above procedures. Reading from this
figure, the true dose rate encountered at H + 36 hours at that location is about 12.0 cGyph.
Tables S-1 through S-4 on pages S-1 through S-4 in the Supplemental Booklet provide the logarithms of
numbers. These tables are not typical logarithm tables. The tables consist of two columns marked A
The logarithm of either quotient is found in Column B. Note that Column A is given to one decimal
place only. To use the table, round the quotient to the nearest single decimal place and locate that
number in Column A. Read the logarithm in Column B.
Example: 10 divided by 6 equals 1.666666667. This number is not listed in Column A. Therefore
round to 1.7. Enter Column A with 1.7. Determine the logarithm from Column B to be 0.230.
