~~ oe HR, badgea all personnel in Hq., JTF-7, TG 7.1, TG 7.5, and certain units of other Task Groups (such ae aerial sampling crews of TG 7.4) were issued "charge-a~plates."' These plates, similar to those used in commercial charge account operations, showed the individual's full name and elght digit ID number. Use of the charge-a-plates eliminated filling out cards by hand, thus speeding up the issuance of badges tremendously. After issuing a badge, all the information was manually punched into ISM cards, which were used with the IBM 704 EDPM, and the information was stored on magnetic tapes. 5.2,.2—All film processing was done by hand using the standard techniques employed at LASL. The film was read with the Eberline Film Badge Evaluation and Recording System, FS-3, in conjunction with an IBM 526 Summary Punch. The FS-3 was developed by the Eberline Instrument Corp., Santa Fe, N. M., in close cooperation with TU-6. The punched IBM cards from the FS-3 were then used to post the records on the IBM 704. This new method of operation proved very satisfactory in that it reduced the number of personnel employed in Dosimetry and Records from 40 during Opera- tion Redwing to a maximum of 16 during Hardtack and considerably reduced the human errors encountered during prior manual operations. §.2.3—Identical film processing stations were established at Eniwetok and Bikini atolls for the issuing, receiving, and processing of film badges. All records of these transactions performed at Bikini were forwarded by IBM Data Transceiver to Eniwetok where a consolidation of information from both atolla was made and stored on tapes with the IBM 704. This method of computation and record posting was quite convenient since the preparation of daily exposure reports and accumulative dosage cards was accomplished simultaneously with the posting of the new information to the 704 tapes for storage. New total dosage information compiled by the 704 was then transmitted back to Bikini by data transceiver, where a duplicate file was maintained for daily use. Compilation and printing of the complete exposure reports at the end of the operation was accomplished by introducing a previously prepared code to the 704. This code extracted the desired information from the storage tapes and directed the printing of the various rosters on the IBM printer. This method eliminated completely the many hours of typing previously required in preparation of these reports. §.2.4—During the operation it was found that the majority of the errors occurring in the dosimetry program resulted from the improper assignment of the eight digit identification numbers. Other errors resulted from improper mariual key-punching of badge issue cards by operators of the 526 Summary Punch. In addition, the operators manually punched film badge numbers into the I8M cards after the FS-3 had automzctically punched the dosage information into the card. The film number read-out system currently being developed by Eberline for use on the FS~3 will eliminate these =~ 48 - ‘ Pree re eee eee key punch errors in the future. Ben a ke ee lm te
