Zeaiisinnh ESTEEon drawing more than one film badge when hedid not know the specific names of the persons to be given each film badge. The form given the person drawing badges was stamped with the badge numbers in sequence at the time ofissuance. These names were added to the sheet as they were reissued by the drawer. When large numbers of badges were issued to a single person, the returned sheets were inserted in the retained file in place of the retained sheets in order to avoid the recopying of a large number of names. The retained file consisted of the forms described above placed in books with Acco fasteners. These sheets had the film badge numbers stamped in sequence in the appropriate column. As a badge was issued, the date issued wasfilled in, as was the issued to column in case several badges were issued to a single person. The nameof the person wearing the badge wasfilled in with the time if it was known. On return of the badges, the names were then transcribed from the sheet returned, or the sheet itself was inserted in place. The dosimeter reading column wasfilled in by the wearer if a dosimeter was carried. The film budge reading (in mr) column wasfilled in as the film badge readings came from the photographic laboratory. The last column was used by the recording section to check each name as the readings were transcribed to the file cards of each individual. An additional column might be used for the name of the organization, as it was extremely difficult to obtain this information at times. The file cards used for the permanent records of each individual were 5 by 8 in., preferably ruled, with columns shown here as Example C. The columns are self-explanatory, gamma readings only being recorded routinely. The greatest difficulty encountered in this filing system was thelack of an initial list of names of persons on whom records had to be kept. A Kardex system was used, but the ad- dition of large numbers of cards at busy times reduced the efficiency of the system tremendously. If initial lists are unavailable, it is believed that a system of loose cards in a file box would be better, so that new cards could be added without continuous reshuffling of the Kardex system.
