C. Bokantuak, Iomelen, Rojkere, Eonjebi The islands between Bikini and Eneu are quite small. Unusually high tides are capable of washing across these low islands, and consequently only scrub brush survives in the sand and coral soil. The four islands were surveyed with G-M counters only. Several transects were made across each island. The radiation levels were quite low and uniform. Most recorded readings were ~10 ur/hr. The range of radiation levels on the four islands was 3ur/hr to 10 wr/hr D. (Table 1). Aerokoj-Eneman Complex The Aerokoj-Eneman Complex, nine miles west of Eneu, is a two-mile chain of five islands connected by partly eroded causeways. Only the western-most island, Eneman, exhibited significant radiation levels. The two eastern islands, Aerokoj and Aerokojlol are connected and almost indistinguishable as separate islands. These two islands were almost completely cleared of vegetation during the testing period. An aircraft runway ran the length of the islands. A water distillation plant and a personnel housing area were located on the southern side of Aerokoj. Some coconut seedlings were found growing quite well around the former campsite. The islands had isolated stands of brush, but not nearly the density of vegetation on Bikini. The ground was grass covered and was used by a considerable number of nesting sea birds. Survey measurements with the scintillation counter and the G-M counter were made along the center of these islands with spot measurements nearer the ocean and lagoon shores. Readings were quite low and uniform, similar to Eneu. The range of G-M counter readings was 3 to 10 ur/hr. The terrestrial gamma exposure rates measured with the scintillation counter ranged from only 1 to 3 ur/hr. Because the radiation levels were so low on these two islands, no soil samples were taken. The longest causeway of the complex connects western Aerokojlol with Bikdrin. This island and the next one quite - 31 -
