Radiation Safety and Cleanup Preparations 187 The RPO is defined by AR 40-i4 as ‘‘the individual designated by the commanderto provide consultation and advice on the degree of hazards associated with ionizing radiation and the effectiveness of measures to control these hazards.”’ The J-2 officer on the JTG staff, an Army colonel or lieutenant colonel (Nuclear Medical Science Officer), was designated as the RPO for Enewetak Atoll. He was assisted by the J-2 staff of radiation specialists. The RCC wasestablished to review procedures involvedin the handling of radioactive materials, to make recommendations concerning protective measures required in radiologically controlled areas, and to monitor the implementation of the Enewetak Atoll radiological protection program. The RCC metat least once a quarter and was chaired by the JTG Deputy Commander/Chiefof Staff. Other committee membersincluded the J-2, whowasalso the recorder, the Engineering ManagementOfficer (J-3), the Assistant J-3 (Atoll Safety Officer), Service Element Commanders, the Staff Surgeon, the Enewetak Radiation Support Project (ERSP) manager, and the FRST NoncommissionedOfficer in Charge (NCOIC).!5 The FRST consisted of 33 USAF personnel who operated the atoll radiation protection program and, at each work site, implemented the procedures contained in the SOPs. Specific functions included hot line control; air sampler operation; issuing, collecting, and reading supplementary personnel dosimetry devices; monitoring personnel and equipment; supervision of radsafe procedures—and changes thereto~on site; and directing decontamination of personnel, facilities, and equipment as required. To implementthe general guidance in the basic documents, andtotailor that guidance to the situations existing at Enewetak, the J-2 and hisstaff developed 18 SOPs and !2 Enewetak Atoll Instructions (EAIs) which, when approved by the RCC and CJTG, provided the workers with the specifics of what to do and how todoit in the field of radiation safety to the end that personnel exposures were as low as reasonably achievable. RADIATION SAFETY AUDIT AND INSPECTION TEAM To provide an independent assessment of the radiological protection program, the Director, DNA chartered a ‘‘Radiation Safety Audit and Inspection Team’’ (RSAIT) and gaveit widest authority to probe into all aspects of the radsafe program. The team was headed by the Director, Armed Forces Radiobiology Research Institute (AFRRI), and included members (generally health physicists) from each of the Services and ERDA/Department of Energy (DOE)
