XT that this experience covers eight operations in which the sampling mission was accomplished by the USAF in an outstanding manner with no knowinjuries, f. That, specifically, routine decontamination of sampling aircraft is required to permit the instrumentation and sample support technicians to work on and in the aircraft, to prevent the build-up of long-lived activity, and increases in the relative background acquired by the airplane on cloud penetration from an otherwise sticky traffic filn, Dr. T. L. Shipman, Health Division Leader for tests, added a few to-the-point remarks on 29 March 1957. 12 "Vie have always gone on the theory that the only good exposure is zero, . . I could not disagree more violently. Perhaps this means that the Air Force is so superior that exposure which might hurt other people do (sic) not damage them and that rules necessary for other people not apply to Air Force personnel, In any event, I feel that this was a most unfortunate statement, . . E can think of no finer argument to justify the decontamination procedures which have been used in the past, This sentence, in effect, says that we may be able to permit sloppy methods and still squeak by. philosophy I take a strong exception," To this Dr. Shipman concluded, * It is my recommendation that the philosophy expressed in this letter should be firmly rejected as it applies to test operations in Nevada and Eniwetok, and most particularly as it applies to sampling planes, What the Air Force wishes to doat their own bases and in their own tactical operations is, of course, no concern of ours," An early report, "Radioactivity in the Cloud Produced by an Atomic Bomb Explosion-Operation SANDSTONE," published on 30 June 1948, long served 238 ARALKO SWEH-2-003), 45" Wh
