Topic A-3 During 1951 and 1952, Desert Rock troops entering test areas had been issued film badges by the Army at Camp Desert Rock which was off the NTS several miles south of Camp Mercury, the main entrance to NTS. Troops were passed through the security gates entering and leaving NIS in convoys for all of the above years of Desert Rock exercises. The 1951 and 1952 Desert Rock film badge results were obtained by REECo from the Lexington Army—Signal Depot in about 1967 during a project intended to centraliee weapons testing exposure records in one file at NTS. in the current file. Thus, these records are Desert Rock troops participating in NTS exercises during 1953 and 1955 were convoyed in and out as above but were not issued one film badge per individual by the Army. Reportedly, one badge per platoon or company was issued by the Army for monitoring purposes. We do not believe we have these film badge results in the file, but we do have some rosters of convoyed troops in our archives, which are currently being evaluated. In 1957, participating Desert Rock troops again were issued film badges at Desert Rock by the Army on an individual basis. In the early 1970's during a reorganization and automation of the records system, AEC obtained microfilms of about 20,000 records located at.Lexington Army Signal Depot, and these 1957 records are in the current file. BEST AVAILABLE COPY While all NTS personnel with NTS security badges have been required to wear film badges from 1957 to the present, there have been a few instances of participants flying over the NTS without NTS film badges and subsequently receiving radiation doses from effluent clouds. Some of these personnel wore film dosimeters from another installation. Records of such exposures are in our file, but the ‘completeness of the record is not known. A very few, perhaps 10 or 20 personnel, were not wearing dosimeters or we have not been notified of their exposures for inclusion in the file. All of the exposure records are on file in a computer and in microfilms. Programs can be written for the computer which will allow retrieval of the data limited by the amount of identification information available in the records. DOE ARCHIVES DOE has prepared amendment to its Privacy Act notice. This will be placed in the Federal Register to permit disclosure of dosimetry information to other Government agencies and contractors with specific needs. / 04
