Who specifically is preparing the report and when will
it be available?
What does “we have developed concentration ratios" mean?
I prefer “estimated” or "approximated" rather than
"developed".

We are not told whether equal weight is given to each 5 cm
increment down to 40 cm to estimate concentration
ratios?
This type of detailed information is needed for
this Advisory Group to evaluate LLL's work.
It could be
provided in the text or in an appendix.

Are they justified in reporting

The average of the 4 quadrants on
Engebi doesn't equal the island average.
Should they?
How were the results for the southern islands determined?

No 24q a, data are given.
Table 2 is incomplete.
Why not?
They should at least indicate the
number of hard data used to estimate each ratio and provide
an estimate of each ratios standard error even though it
may only be approximate.

Bennett's model is not used to correlate Sr-90 in diet with
that in bone.
That is, Enewetak’s data (observations) are no
available on both variables for which a correlation coefficie
can be computed.
Bennett's model is a way of approximating
