4. AD.MINISTRATIVE ADD LOGISTICAL WATICRS The administrative and logistical matters involved in Project 6.4 are grouped as (a) test preparation, (b) roll-up of the project, ed (c) logistics and support services for the test. 4.1 Test Preparation, Laboratory The test preparation on a leboratory scale involves pre-test experimentation to determine optimum methods and procedures for obtaining the desired data; evaluation and calibration of instruments and devices; and the training of personnel for their various assiznments. These oper- ations are described briefly below, as they pertain to the individuel sub- projects, and details are given in Amexes A to Jd. 4. 1.1 Viashdown No laboratory pre-test work. 4.1.2 Ship Decontamination Laboratory work on ship decontamination methods will be carried out in order to determine the influence of such factors as weathering, surface deposits, and repeated contamination-decontamination ou the effectiveness of the proposed decontamination methods. Suitable additives will be tested, and mechanical performance of decontamination equipment will be studied. 4.1.3 Aircraft Study For the aircraft study, a series of tests have been con- ducted using fluorescent simulant on aircraft sections subjected to small-scale washdown. A nozzle arrangement has been set up and tested on a dud F4U4, to determine the optimum location of each nozzle in covering the aircraft with an adequate flow of water. A pre-test study has been made of the cleaning agents to be used with the aircraft decontamination equipment, and the aircraft have also been modified for loading. 4.1.4 Survey and Photography ST. LOUIS FRC Test preparation for survey and photography includes evaluating the portable beta probes; testing the correlation of beta readings with directional gamma readings; testing a newly designed wipe sampler; testing the camera and synchronizer to be used to detect the fallout on Baker; and training the enlisted personnel assigned as radiolorical o survey monitors. 009521
