W. J. Bair June 1 8, 1979 Page 5 9. p.5 Lines 10-25 Additional details on Analytical Procedures and External Gamma Measurements should be given even though other other references cover these topics in detail. 10. 11. p. 5 Last 2 lines p. 6, Line 13 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". 12. p. 6 Lines 19,20 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. 13. p. 6 and Table j (p. 23) Are these average doses? median? If so, what average, the mean or How many readings were taken per island? precise are these averages? about each number? How What is the standard error Are they justified in reporting 3 significant figures? 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? 14. p. 6 Lines 1-3 15. - p. 6 Lines 12-20, Table 2 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. 16. p. 6 Line 6 from bottom The assumption is made that ratios do not depend on soil concentration level, island, or time. explicitly stated and justified. 17. op. 7 Line 4 from bottom This should be ‘ 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
