Some types of activities required badging an entire group. ple, For exam- film badges were issued on D-1 of each shot to all crewmembers of TG 7.4 sampling aircraft and to crewmembers of any other aircraft expected to fly within 100 nmi (185 km) of the shot site at H-hour. Badges were issued at the radsafe centers to parties entering radiological exclusion (radex) areas. The records do not specify whether a badge was issued to each member of a party or a single badge was used to represent doses for the entire party. All film badge processing and maintenance of dose record cards for ail personnel was performed by TU 7 of TG 7.1 in compliance with JTF 7 regulations. Personnel Exposure Sheets were used by a large percentage of units and groups during CASTLE to keep track of personal identification data, issue and return date for individual film badges, and recorded radiation exposure. In some cases these sheets were also modified to include date of pocket dosimeter issue and the exposure reading upon return that same day. Although established procedures called for transfer of individual badge information to 5- x 8-inch record cards, only about 50 percent of CASTLE dosimetry data were entered on these record cards. In general, most TG 7.3 dose data were cumulated on lists of shipboard personnel ra- ther than the 5x8 cards. The 5x8 record cards, “Individual Accumulative Radiation Exposure Rec~- ord,” were developed in two different formats. One version of the form included badge number, date of development of the badge, the film badge reading in milliroentgens, and an accumulated dose [sic] column (also in milliroentgens). Another format provided issue dates of both film badges and pocket dosimeters, the exposure in milliroentgens for both (if recorded), and an accumulated exposure column in milliroentgens used to total film badge readings. Although attempts were made to provide all data on the cards or Personnel Exposure Sheets, not all fields were always completed. 103
