mm = Project 2.4 ~iDecontamination and Protection - J. C. Maloney OBJECTIVES To study the contamination of various types of building surfaces exposed at various orientations to the fallout. To study the effectiveness of various decontamination procedures, and thus obtain data on the radiological recovery of military installations constructed from the tested types of material, INSTRUMENTATION Panels of the various types of building materials were mounted on a structure so as present various orientations to the fallout. were mounted on the forward portion of YAG 39 and YAG 40. The structures Evaluation vat to be carried out at Elmer, where various decontamination methods were to be used on the panels, The effectiveness of decontamination was to be assessed by survey and some radiochemical and radio physical investigations of the panels and decontamination wastes. RESULTS Bee Deel, No fallout was received by the YAG's on CHEROKEE. 4 ~ 25 Me COPIEDILOE oOwee{ LANL RC
