"Liaison activities.--Arrangements were made to keep those health officials who might be primarily concerned, informed of the activities at the test site. The States normally involved were Nevada, Utah, California,-and Arizona, and the State health officers of these States were advised routinely by phone of any fallout situation that might affect areas under their jurisdiction. The personnel advised in these instances were: Nevada: Dr. Daniel J. Hurley, State health officer. Utah: Dr. George A. Spendlove, State health officer. California: Dr. John M. Heslep, designate of State health officer. Arizona: Dr. C. G. Salsbury, State health officer. "In addition to these arrangements, contacts were made with affected USPHS officials and with local health officials. "Activities of zone personnel.-~Zone personnel conducted a publicrelations program on an informal and down-to-earth basis. They formed a wide acquaintance in their respective areas, participated in local events and took their instructions to become a part of the community seriously; as for example, the monitor at Glendale who became a Sunday school teacher, or the one in Alamo who plastered a ceiling in one of the hotel rooms. Such intimate association with the people in the area was good practical public relations, and while it may not have altered completely basic public opinion regarding the tests, it at least made the explanations of zone personnel more acceptable. RADIOACTIVE FALLOUT AND ITS EFFECTS ON MAN "Every opportunity to reach the public through talks and film show- ings was accepted. Practically every person throughout the off-site area saw at least one film and listened to at least one discussion by monitors. This was accomplished through civic clubs, schools and PTA, and other groups. In this connection, it should be stated that the new film Atomic Tests in Nevada received enthusiastic reception. From the remarks made to zone personnel, it appears that general feeling was that, for the first time, the public was being shown exactly what happened during a shot. "A complete listing of public relations contacts is not available, but the partial list of film showings tabulated in table 1 will indicate: the scope of this activity: em 0523 250
