The second incident that created another group of easily observed overexposures in the dosimetry records was the 12-man crew of a C-54 photo plane; the crewmembers received doses between 8.6 and 11/6 rem. This plane was on a mission to take aerial pictures of the MIKE crater and was i) “4 “| Caught in fallout. In both incidents the corrective measures possible were taken, i.e., early ending of the mission and prompt return to base for decontamination, = > : r flying through available rainshowers to aid in decontamination on the return flight. The exposure records of the task force as a whole seem to accurately : reflect the operations that took place; i.e., men who were exposed were < badged and the badges appear to reflect the exposure potential of what is known about the activity. Possible exceptions to this are the crewmembers of the USS Arikara, who were slightly contaminated during the recovery of — = a buoy following MIKE but whose badges registered a zero exposure. _-— Perhaps the contamination was so low (0.5 mR) and the decontamination so prompt that the badges did not respond. The summary statistics in Tables 11.1 and 11.2 present the exposures by Service and by task force component. Averages (arithmetic means) have been derived from the records in order to make a simple presentation. points, however, should be noted. 11-2 Two
