wear the badges throughout the series. (Infants and small children are likely to chew or otherwise damage the badges, making it impossible to obtain accurate measurements, or to damage themselves swallowing the badges.) . ‘ \ A more detailed program has been established at Alamo, a town of about 400 persons located 55 miles northwest of the Yucca Flat firing area. Alamo was chosen as a bepresentative town of the Test Site region, ' In addition to wearing film badges, Alamo residents are asked to report their movements inside the region and to other localities, and also to provide information on other activities which might affect radiation dosage, such as the amount of time spent indoors as compared.with outdoors, Each person also is being asked for details of previous exposure to radiation, such as medical X-rays. This project has two major purposes: (1) To obtain information on how fallout radiation exposures (2) To obtain information on the problems which might be en- are affected by movement, shielding provided by buildings, weathering of the fallout material by wind and rain, and other factors, countered in attempting to record the radiation exposure of a rela- tively large group of persons through the use of film badges. Physicians and Veterinarians Two physicians of the U. S. Public Health Service have been assigned to the Test Organization at Camp Mercury for the duration of the 1957 series. They are Dr. Samuel C. Ingraham and Dr. Eugene Van der Smissen, both of Washington, D.C. Dr. Ingraham serves as coordinator within the Test Organization for the USPHS National Monitoring Network, Their duties include maintaining liaison with private physicians in the NTS region and assisting them in diagnosing any ailment which the patient feels may have resulted from any test effect, including exposure to radiation, Two veterinarians are serving the Test Organization in maintaining liaison with regional veterinarians, public officials and stockmen, and in investigating alleged test-effected injuries to animals. They are Lt. Edward L. Johnson, who is permanently assigned to the Atomic Energy Commission's Las Vegas Office, and Dr. Arthur H. Wolff, Senior Veterinarian with the Occupational Health Division of the Public Health Service at Cincinnati, Ohio who has been assigned to serve during the series. Automatic Radiation Reporting System At least 30 continuous radiation recorders have been placed in nearby communities to record the time of arrival of any fallout, Co intensity, and in some cases, the effect of shielding by structures. a 7 - 55 a \ FO
