A single film badge system was used during the operation with exchanges being made every eight weeks and when personnel returned from full radex areas. Total dosage records were kept current daily through the use of the following equipment: IEX 704 Computer, IEM 526 Summary Punch, IEM 062 Sorter, IEM 026 Key Punch, JEM 056 Verifier, IE 519 Reproducer, IEM 552 Interpreter, IBi 066 Date Transceiver, and the Everline FD~1l Film Badge Evaluation System configured to feed the IEM 524 Summary Punch.

Remaining badges were used for calibration purposes and by project personnel as special programs required their use. As of 1 August, a total of 19,000 persons had been issued film badges. Twenty persons were utilized in dosimetry, nine at Bikini and eleven at Eniwetok,. Only film processing and filing was done mamally. The maximum permissible dosage was established as 3.75 r for any 13 week period with 5 r being the upper limit for the entire operation. The one exception to this decision was that sampler aircraft pilots were allowed 10 r for the operation. As of 1 August 1958, only four persons had exceedt ed the 5 r maximum permissible dose, e625 Conclusions.
