TRANSIT BLUE BOOK AWNEX H SHIELDING STUDIES Task Organization C. F. Ksanda, group leader Vie E. Strope 1. GENCRAL SITUATION 1.1 General Same as in basic plan. 1.2 Nature and Scope of Test This study will be conducted to provide information on the effectiveness of a ship's structure in reducing the gamma radiation hazard from radioactive material which is enveloping the ship and which has been deposited on the weather surfaces, Measurements will be made of the dose rate as a function of time in locations below the weather deck and in superstructure compartments. Integrated doses will also be measured. Detailed monitoring will be conducted to determine the variation of dose rate within a given compartment. Dose-rate measurements will also be made within a series of pipes of various thicknesses on deck to provide a means of estimating the effective photon energy of the radiation as a function of time. 1.5 Purpose of Annex 1.3.1 To describe in detail the objectives and plan of attack on Project 6.4h. 1.3.2 To provide detailed information on the operational and 1.4 ST, LOUIS inemy Forces Ty logistic requirements of Project 6.4h. eC Same as in basic plan.
