Row of Dwellings - Complete except for Windows, Ejit Island to their atoll was completed on 5 June. As a result of the BRAVO fall-out incident, a joint AEC-DOD Project 4.1 was established to study the physi- ological symptoms of evacuated natives. Subsequent to the BRAVO shot, many pre-test plans were either abandoned or greatly modified due to the widespread destruction offacilities on several of the sites and radioactive contamination over much of Bikini Atoll. The changes in shot sequence necessitated the following scientific station substitutions: Station 9@ for Station 30 (second shot); Station 50 for Station 40 (third shot); Station 1581 (Japtan) for Station 1580.01 (Enyu) ; Station 712 (Runit) for Station 710 (Enyu). Station 10 was relocated from the Bikini Lagoon to the Elugelab crater at Eniwetok Atoll, Radioactive contamination necessitated a new barge Station 1840.01 at Bikini in lieu of Station 1820.02. Support services, furnished by Contractor personnel of TG 7.5 to various participating agencies, were also severely taxes by the numerous program changes. Extra demands for a wide range of skilled labor, tools and equipment needed in the handling, unpacking, moving and installing of scientific equipment hadto be met. The original plan for re~occupation of Enyu and Eninman camps were, of necessity, abandoned, thus requiring the evacuation of 1330 men from Bikini Atoll to Eniwetok Atoll. Of this number, 200 were TG 7.2 and TG 7.4 personnel who were quartered on Eniwetok Island; the balance of 1130 men were TG 7.1 and TG 7.5 personnel who were quartered aeig CopledJ/DOE LANL, J-Div. 1A CUTEST TT EPICTCT ICRI TRC KLE KCK TILL KCK IRE WL T TLV Figure 7.
