The 5x8 record cards and the Personnel Exposure Sheets were updated with exposure information (when possible) ter developing and/or reading. as soon as it was available af- The 5x8 record cards were used as a cur- rent tabulation of personnel exposure. This system was designed to inform the monitors of the total dose received by any task group member. Even sO, Overexposures sometimes occurred because of the time required for processing, posting the results, and notifying affected personnel. At the conclusion of CASTLE, the record cards and Personnel Exposure Sheets were transferred to CTG 7.1, who was responsible for keeping total dose records on the entire task force. For most units where 5x8 record cards were not used, rosters of shipboard personnel were used to list and total all badge readings for each individual. These unit master lists and the 5x8 record cards were used to develop the Consolidated List of CASTLE Radiological Exposures (Reference 13), which was used as the basis for the dose tabulations in Chapters 6 through 10. Although the Consolidated List does not distinguish between exposures determined from film badges and those calculated or assessed, these data are often obtainable from the 5x8 record cards or the Personnel Exposure Sheets. In the process of accumulating the names for the Consolidated List, some badges with zero readings were ignored. Therefore, a badged individ- ual who had only zero readings may not appear on the Consolidated List. This practice was not uniform, but a cursory examination of the microfilm record (Reference 87) that contains the Personnel Exposure Sheets, the 5x8 cards, and the rosters of shipboard personnel reveals that men with badges issued at the Enewetak airfield with zero readings do not appear on the Consolidated List unless, of course, they were issued another badge at another time that did indicate exposure. The extent of this is difficult to judge without examining all the microfilmed records. TG 7.4 (Air Force) Personnel of were primarily affected, and the Consolidated List er- roneously indicates that less than half were badged; the Naval Air Station at Kwajalein also ignored zero readings in cumulating badged personnel. This has no significance for assessing the total radiological exposure; 104
