the atoll islands was conducted at approximately H+4. This survey was conclusive enough to limit scientific recovery to the southern and eastern islands. The survey, whose readings are shown in Table 55, indicated that radioactive contamination extended north of a line from Bokoluo to Billae. Secondary fallout, amounting to 0.002 R/hr, was experienced at Parry on the evening of the detonation. Lagoon water was moderately contaminated in the vicinity of the Bokoluo-Dridrilbwij chain but cleared within 2 days. Table 55. Island CASTLE, NECTAR radiation summary (R/hr).

Source: Reference 91. The fallout pattern on the northern end of Enewetak Atoll (Figure 95), was documented by fallout samples from land and raft stations, and by radsafe surveys on land. The aerial survey operated north of the atoll to determine NECTAR fallout areas and contours, which are shown in Figure 96. 320
