GAMMA EXPOSURES 11.16 Following an unexpected fallout over Sites Elmer and Fred resulting from the FIR and KOA detonations on 12 and 13 May, it became necessary to request that the guide of 3.75r for a 13-week period be increased and the 5.0r for the Operation be raised to 10.0r for 35 key H&N personnel whose absence from EPG would have seriously handicapped the Operation. This fallout produced an additiona] radiation dose to the end of the Operation ranging from 100 to 1500 mr, depending upon the length of time a person remained at those sites. The request for increasing the guide limit for these individuals was approved by CJTF-Seven. 11.17 Of the total of 3464 TG 7.5 personnel ation listed on the summary report for OperHARDTACK, the exposures can be broken down as follows: To maintain the records of radiation exposure for all TG 7.5 personnel; an i.
