to record the pertinent data on all personnel involved in 4| Ae ca ee bh Lenngh DNA Ceorsres 3, Indiv i due) the cleanup and, for those working with radioactive materials, to record all exposures. The data base includes a record of operational activities, the type of work being done, location, air sampler readings, radiation Survey readings, personnel dosimetry and urine sample results. These records will be stored permanently, and a computer-based ready- retrieval system is being developed. | Other permanent records are being kept as well. Prior to arriving on the Atoll individuals undergo pre-deployment physical examinations which pay special attention to past history of exposure to ionizing radiation and baseline blood counts. The results are entered in individual permanent medical records. The monthly film badges from Enewetak are processed by Lexington Blue Grass Army Depot Activity, which maintains its own permanent record of the results, and sends a copy to the Joint Task Group Radiological Pro- ‘795 tection Officer for entry in individual medical records.~—'_.. Thus any exposure received by an individual while on the Atoll will be entered in his own medical record as well as into the DNA central data base. Should exposures warrant, whether recorded by dosimetry or shown by bioassay results, follow-up examinations and tests will be instituted. extmoe d a ky In summary, we are providing every possiblé) protection to personnel engaged in work with radioactive materials. The protection is so extensive that audit and inspection teams have repeatedly advised that the measures are overly protective, considering the hazard involved, and should be reduced. We are providing what is probably the most complete record system ever established for any operation involving radioactive materials. It has been, and will continue to be, our objective to insure that personnel exposures to radiation are limited to the lowest levels practicable, and that safety of personnel is the overriding priority in the operation. On behalf of the Secretary of Defense, and all of us involved in the cleanup project, I would like to express appreciation for your interest and concern over the health and safety aspects of this difficult but most important mission. I stand ready to brief you or your staff, or to provide any additional information desired. Sincerely, 19 Enclosures sO See attached listing FY | dae TN | wal fo ° . S010922 © G R. R.
