Statistical Analysis of Data
In the cases of 1376., $320 and 52, a large set of individual aduit
values for k and P° were available in addition to a set of adult average values.
The whole-body counting techniques and urine bioassay techniques employed were
similar throughout the programs’ history.
The short-term factors influencing
the pattern of an individual's body burden, e.g. sickness, local diet changes,
eating imported food, recent travel to uncontaminated areas, etc. were factors
which influenced the pattern of adult average body burden throughout the entire
residence interval.
Therefore the ratio of the standard deviation to the adult
average k's and P°'s should have been equal to the same ratio for individual
adult values.
This was in fact the case for 1374, , 6520 and 9...
The standard
deviations and the adult average k's and P°'s for these nuclides were listed in
Table 4.
Tables of individual adult values were not reproduced here, however,
individual body-burden data obtained in sequence are found in the references
given in the introduction.
These body burdens may be used with a fitting func-
tion (Eq. 2) to generate individual adult, k's and P°'s.
The standard deviations for adult average k's and P°'s were used to estimate the standard deviations for adult average committed effective dose equivalents (see Table 4).
Because the ratio of standard deviation to the average k
and P° was the same for either adult average or individual adult k and P° data
