— 166 = =RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL equipment operators, and because the face plates were set out from the face to provide moreair circulation within the mask and hence greater wearer comfort, an important factor in the tropical climate. M17 standarg military masks were not used because of possible plutonium migration through the filter cartridges and the tight facial contact. The antj- contamination suits chosen were light-weight and cotton, thus providing protection with minimal discomfort. None of these items had been used by troops in a tropical atoll environment, but they were: well tested anq proved excellent choices at Enewetak. 72 ENEWETAK RADIOLOGICAL SUPPORT PROJECT DEPLOYMENT: 28 JUNE 1977 ERDA-NVoffice provided two distinctly different types of support to the Enewetak Radiological Cleanup Project: a. Base operations and maintenance support were furnished through ERDA-PASO, directed by Mr. Stanley, and through H&N-PTD, whose General Manager was Mr. Donald J. Brush. The ERDA-PASO Site Representative position at Enewetak was manned by personnel from their Hickam AFBoffice on a rotational, temporary-duty basis. b. Radiological support for the cleanup project was managed by ERDANV as a project; i.e., the Enewetak Radiological Support Project (ERSP). The ERSP Project Manager was Mr. Roger Ray, ‘then Assistant Manager for Environment and Safety, ERDA-NV. ERSP was organized as shown in Figure 3-13. Staff support was furnished by ERDA-NV and ERDA-PASOas required. On-site operations were directed by the Project Manager or, in his absence, one of the Deputy Project Managers serving on rotational assignments. They were assisted from time to time by technical representatives from the ERDA-NVoffice. Three ERDA-NVcontractors were assigned to the ERSP project: a. EG&G, Inc. equipped, maintained, and operated van-mounted radiation detection measurement and data recording systems. EG&G also performed the reduction, analysis, and interpretation of data from these systems. b. Eberline Instrument Corporation (EIC) equipped, maintained, and operatedfield analytical and instrumentcalibration laboratories. c. Desert Research Institute (DRI) assisted in the on-site interpretation and mappingofdata collected by EG&G. DRIalso provided advice as to samplingareas and arrays as requested by the Project Manager. 73 To comply with Congressional direction, enlisted specialists from the Navy andAir Force were assigned to maintain radiological equipment and to assist in the laboratory and in field survey work.
