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, indica fred that radioactive contamination extended north of a line from Bokoluo to Billae. Secondary fallout, amounting to 0.002 R/hr, was experienced at Par fy on the evening of the detonation. Lagoon water was moderately contam Inated in the vicinity of the Bokoluo-Dridrilbwij chain but cleared withip 2 days. Table 55. Island H+4 a CASTLE, NECTAR radiation summary (R/hr).

The fallout pattern on the northern end of Enewetak Atoll (Fig@re 95), was documented by fallout samples from land and raft stations, andjJby radSafe surveys on land. The aerial survey operated north of the ato] to determine NECTAR fallout areas and contours, 320 which are shown in Figure 96.
