1.6.3 It is essumed that the test aircraft vill be contaminated (at the location aboard the test ship) in the same manner end to the seme extent in this operation that they vould at any locetion on the flight deck of an eircraft carrier, 1.6.4 The dose to the pilot of the aircraft, as measured on the tio ships, will have two contributors; dose from the aircraft end dose from the ship's surfaces (deck, ote.), It is assumed that it will be possible to separete the contributions of each of these sources, so thet the situation existing with many aircraft and a wider deck can be computed, 1.6.5 Information gained at this test rogarding the contanin=- 1.6.6 It is presently extremely difficult to calculate the ability, distribution of contamination, decontaminability, effect of decontamination methods and matcrials, end requirements during decontamination of manpover, materials and time can he uscd in planning for the recovery of contamineted aircraft afloct end ashore, shielding afforded cither the pilot or the crewmen by the airplenes structure, An attempt will be: made to compute this shielding value, but if it is not computable, any multiplication of doso rates as in 1.6.4 will be of limited accuracy, 2. MISSION 2.1 To obtain information necessary to determine the protective veluc end feasibility of the ships washdorn system in protecting parked aircraft ebosrd ship, and to evaluate selected decontamination techniques and materials, 2.2 To obtain informetion necessary to compute the hezards to operetion of aircraft on carriors following contaminetion by an etomic ticapon . 3, TASKS AND PLAN OF JTTACK 3,1 ST, bGOUis rae Redietion in and around Each Aircrsft aboard Ship The test circraft will be pleced abocrd ABLE cnd BAKER in identicel locntions on the #5 cargo hatch cover, &t throe locations: (1) in the cockpit; (2) above tho deck in front of the aircraft, and (3) in » location similar to (2) on #4 hetch, will be pleced spherical- geonctry ionizetion ch:mbcrs attached to continuous recording mechanisms. 62
