SLIDE 5 Whole-body dose estimates. On Rongerik Atoll, a military outpost, a set of film badges were present and readings were obtained (8055). Monitoring instrument readings and the film badge results led Sondhaus to postulate total gamma exposures, from the tipe fallout began up to the time of evacuation, of 0.027, 0.022 and 0.018 C kg (106, 86 and 70 R) based on three assumed fallout durations of 8, 12 and 16 hours, respectively. One film badge remained outdoors at _Rongerik from the time of fallout to evacuation and (98 R). recorded 0.025 C kg~ The values for whole-body dose estimated by Dunning, Sondhaus and those estimated by Lessard who used fallout composition studies, are in reasonable agreement. These last two approaches were different from each other in that Sondhaus derived the estimate of whole-body dose from actual measurements of total exposure (film badges at Rongerik) and exposure rate, while the estimate by Lessard depended upon measurements of the composition of fallout, living pattern corrections, and exposure rate measurements made by survey teams during evacuation efforts. The approach used by Peterson depended on upperair wind level patterns and the fallout was estimated by him to drift in a southerly fashion. This was not in agreement with assumptions used in three previous and independent approaches (Ha79). The Peterson results for whole- body dose were, therefore, radically different from other estimates for persons located at Rongerik and Utirik and do not coincide with measured values for exposure and exposure rate (Sh57). It was not clear which exposure rate measurements were accepted by Peterson for normalizing his meteorology based results. It is clear that he accepted one measurement at some location. He may have purposely overlooked measured exposure rates in deference to upper-air wind patterns (Pe81).
