_ 5==(FLATHEAD) Project 2,8 — Shipboard Countermeasures Methods Studies - R. H. Heiskell Objective To determine the relative effectiveness of various proposed ship and personnel protection and reclamation methods, Description and Experimental Procedures These studies consisted of 8 problems to be carried out on the YAG=39 and YAG=40 and at the Rad-Safe center on Parry, These eight problems involved the study of the effectiveness of various shipboard protective methods, decontamination methods, hazard assessment methods, personnel protection and decontamination methods, and basic contaminab= ility-decontaminability. Results and Conclusions The removability of the RRPC was the same as experienced after the (ZUNI). yr Decontamination effectiveness was superior to that obtained on theJ ). moval left only 3.9% In the nonewashdown area the RRPC ree residual as compared to 18 percent residual as for hand and mechanical scrubbing. Chemical Paint Stripping: No results due to insufficient activity. Mgchanical Serubbing Methods: n (ZUNI) shot. Results same as obtained after the The mechanical scrubber was found to be slightly inferior to hand scrubbing. It was, however, far superior to hand serubb- ing in reducing fatigue. Protection and Decontamination of miscellaneous materials, wood decks, and skin: Insufficient activity to obtain useful data, Monitoring and Hazard Assessment, and Basic Contamination-Decontam— ination Studies: ocr P0/D0E F L8G Data is being processed. 36
