ducting of each ship, will be measured both vith bete instruments and directional gamma instruments before any cecontamination operations arg undertaken, (See Tab B-l for monitoring plen and availeble results), All measurements will be made by 6.44, 3.2 snd Measurements will be mado by moans of fixed gamma monitoring instruments, beta instruments, radiac instruments and directioncl gamma instruments to determine (1) the progressive and over-all effectiveness of each decontamination procedure, and (2) the individual effectivonesses of the steps, or mothods, constituting cach procedure, The measuroments will be made at established locations, or stetions, and a total of 138 zone surveys will be required (sce Tab Bel), Tho number of additional surveys which mey be required for the boiler air ducts, ventiletion com- partments and mechinery spaces, is problematical, accomplished by 6.44. 3.3 Surveys will be Effoctiveness of Decontamination Procedures Upon the completion of initial surveys and following the removal of test aircraft and tost samples, decontamination procedures will be conducted on both ships, 3.3.1 Equipment to be Used Sec Scction 4.5. 3,3.2 Deocontominetion Procedurcts These are described in Tab Bx2, 3.3.3 Efficiency of Contamination Remove , This measuremont vill be used to detcrmino the amount of rusidval activity removable from ABLE after weshdown, and the amount of original activity removeblo from BAKER in the absence of weshdown, Residual contaminetion vill be moasured efter each step (method) of each decontamination procedure to obtain the indiceted officiency of each step and the total efficiency of the procedure, These results will be of importance in the ultimate prepcration of an operrtional pien for the recovery of ships, Available results ere given in Tab Be2, 3.34 Cost of Decontaminetion ST.
