=PsEoBeD PY TS - 0018933 The above example illustrates the inconsistencies in the data and points out the need for caution in making interpretations based on them. 3-3 COMPARISON WITH THE RESULTS OF PREVIOUS TESTS Shots were fired during Operation Redwing under conditions similar to those of the present series and some data are available from published reports which may be used for comparison purposes. Results on the No”? to Kr88 ratios and sr79 R-values as a function of altitude in the cloud for the first four hours are reproduced in Table 3.11 from Reference 26. It is noted that for the land and reef shots the Sr?9 R-values increase and the Mo?? to Kr88 ratios decrease in a way On the water shots the sr? generally comparable to the similar Hardtack events. R-values are nearly constant with altitude, as with Walnut, but the Mo?? to Kr 88 ratios are not comparable. The fallout R-values for the Hardtack shots are generally not inconsistent with those arrived at for the Redwing shots by Project 2.63. The latter gave radionuclide compositions which geerate computed decay curves in good agreement with those actually measured on several different types of instruments. The R-valu from Redwing are listed in Table 3.12. Table 3.12 R-VALUES FOR REDWING n??(90) Shot.
