An additional modification included a turbulent wake correction to large granules falling from the Stratosphere. Parameters for a tropical atmosphere were incorporated into gran- ule fall velocity calculations. An assumption was made that theactivity per granule increased as the cube of granule radius increased. The analytical approach has been described by Peterson (Pe8l). 2. Comparison of Peterson's Whole-Body Dose Estimates. The cumulated whole-body dose was integrated from the onset of fallout to evacuation time. Peterson calculated the diffusion of fallout using computer codes and upper-air wind-level patterns. Peterson's results for whole-body dose were. compared to es- timates by Dunning (JCAES7) and Sondhaus (Cr56), and an estimate based on our analysis of Bikini ash. Sondhaus's work was detailed (S055); the whole-body dose was based on exposure-race measurements and a range of assumed times for the onset and cessation of fallout. Sondhaus's best estimate of whole~body dose ig given in Table -2, as are Peterson's estimate, the Dunning estimate, and the Bikini ash result (see column labeled ‘This Report'). The values for whole-body dose estimated by Dunning and Sondhaus, and those estimated by the method indicated in Section II.D of this report are in Table 2 Comparison of Cumulated Whole-Body Dose, Rad?
