Attachment 3 T. L. Shipman to Alvin C. Graves, Decontamination of Aircraft at Tests, 3/29/57 Al Graves, J-Division Leader March 29, 1957 T. L. Shipman, M.D., Health Division Leader DECONTAMINATION OF AIRCRAFT AT TESTS K-257 The following are my comments on the letter signed by Col. Kieffer, dated March 21, and addressed to Mr. Hertford. In essence, this is a proposal that decontamination procedures on aircraft during a test operation be virtually eliminated unless there is a specific operational requirement which requires decontamination. Under ideal circumstances, I have very little objection to such a procedure but I would like to point out that there seems to be creeping in here a philosophy which is quite contrary to everything which we have held to be right and proper in the past. I should make it clear that my remarks here are not directed at normal USAF operations; I am concerned solely with what happens when Air Force planes participate in tests. The basic philosophy herein expressed is that there is no biological or moral objection to permitting personnel to receive exposures up to some predetermined level, regardless of the necessity of this exposure and regardless of whether or not it might be avoided. We have always gone on the theory that the only good exposure is more. We accept the fact that certain operations which must be performed in laboratories or at tests simply cannot be done without accepting some exposure. In performing these operations, however, we have always made every effort to keep the exposure at the lowest possible level. This sometimes necessitates fairly elaborate and expensive safeguards, and sometimes delay. In Par. 1 of Col. Kieffer's letter is stated that past experience in tests indicates that decontamination of planes is not required "for reasons of personal safety except in unusual circumstances ....." I would accept this phrase if it were reworded to say that decontamination has not been necessary to prevent overexposures. In the second paragraph it is stated that the elaborate promotions followed in past tests are inconsistent with the point of view they are trying to establish within the Air Force and that they are not practicing what they preach. If this means that the Air Force is trying to indoctrinate its personnel with the belief that moderate exposures may be received with impugnity, I could not disagree more violently. Perhaps this means that the Air Force is so superior that exposures which might hurt other people do not damage them and that rules necessary for other people do not apply to Air Force personnel. In any event, I feel that this was a most unfortunate statement. The final paragraph of Col. Kieffer's letter states that while some exposures to ground crews might exceed the test limit, the Air Force will keep its own records and take care of anyone who gets hurt. In other words, this means - 1 - Al Graves, J-DO March 29, 1957 that Air Force personnel participating in tests are no longer to be bound by standards and procedures which have been developed for other less fortunate (or should I say more fortunate) individuals. Attached to Col. Kieffer's letter is a page having to do with rad-safe experience in past tests. The final paragraph of this enclosure states: "If a reduced decontamination effort doubled this average dosage (less than 1 r per test), the 300 mr per week or 3.0 r test limit would still be met." I 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 sneak by. To this philosophy I take strong exception. There are a number of arguments on the side of routine decontamination of aircraft which have, in my opinion, been overlooked. 1. Without decontamination there will be inevitable migration of contamination carrying activity to other areas where it may be very undesirable. This letter has completely overlooked the fact that people working at test invariably have neighbors with special requirements. 2. Failure to decontaminate will produce a buildup of long-lived beta-gamma contamination and the same would probably be true of alpha contamination under certain circumstances. 3. The trucks and other equipment for decontamination already exist; the detergent materials used have been furnished by LASL for the reason that these materials were superior to those furnished by the Air Force. 4. A 3-day separation between shots in the contemplated tests cannot be counted on. While there may be a 3-day period between shots, aircraft and crews may have to be in a state of readiness more frequently. 5. The current system of routine decontamination was originally instituted by Karl Boughton and Hal Plank on the basis of SANDSTONE reports that the exceedingly high contamination on the planes used in that operation resulted from the dirty, greasy condition of the planes. It is my recommendation that the philosophy expressed in this letter should be firmly rejected as it applies to test operations in ILLEGIBLE and Eniwstok, and must particularly as it applies to sampling planes. What the Air Force wishes to do at their own bases and in their own tactical operations is, of course, no concern of ours. ORIGINAL SIGNED BY THOMAS L. SHIPMAN, M.D. T. L. SHIPMAN, M.D., c1A - A.
