.4.1.5 Interior Contamination Study At the Laboratory, pre-test work has included: testing of different filtering elements for pressure-drop characteristics and general adequacy for use in the air saupler; construction and testing of reduced-scale boiler model and a full-scale ventilation system; preparation of prototype air samplers, particle collector, and beta-decay monitors; construction of counting chambers; and duct section design. 4.1.6 Instrumentation A discussion of instrument procurement, design, and testing is conteined in Annex F, 4.1.7 Radiological Safety It will be necessary to properly indoctrinate Project 6.4 personnel in the radiological safety aspects of their particular problem. Special lectures and training programs will be gi-en to those personnel available at USNPDL prior to departure for the test site. Additional training will be given by the Treasure Island Training School. Radiological safety instruments will be procured and will be tested in the Laboratory simulating expected conditions. Pre-test work on the shielding study has planned a simplified shielding experiment using a gamma source of known energy. The pre-test work on gemma instrumentation, dosimetric devices, and radiac sets has some bearing.on the shielding study. 4.1.9 Air Monitoring The air-monitoring study is to conduct simulated test runs at USNRDL, using Sr°O calibration samples, and X-ray and gamma-ray backgrounds, so as to determine the versatility of the air-monitoring instrument. tUxtra shielding and other adjustments as may be necessary will be added, and the instrument will be calibrated prior to shipboard installation. ST. Louis FRC 4.1.10 Panel Study (6.5) For the study of construction material panels, pre-test work is to be done at the Army Chemical Center, where representative construction materials will be s-lected and panels designed to house these materials. Appropriate protective coatings for the construction materials will also be selected. 009521 14
