/ ’ cn ‘ TASK UNIT 7 - J. D. SERVIS, Mid, USA (J. D. Servis, Maj, USA) RADIOLOGICAL SAFETY ° An A damage and radiation survey was conducted at Ht hours f ME wh; survey covered the islands of the atoll and was conclusive eno to Limit reentry to Enyu and Airukiiji on the first day. This survey indicated that recontamination was extensive throughout the atoll and lagoon both to the east and west. No significant secondary fall-out was encoimtered at Bikini as a result of this detonation. Lagoon water was heavily contaminated with radioactive sediment. Readings of 1 r/hr were obtained at 100 feet altitude in the vicinity of zero point | “ng shot day. . l day. Floating objects revealed readings of 1 to 3 r/hr on Small boats and barges in Bikini - Enyu anchorage were contaminated to a moderate degree (1 - 6 r/hr). Lagoon flushing through the southwest passage materially increased radiation levels in Eniirikku <= Bokororyuru areas. Results are show in Table 7-1, -9/7-
