5. An hourly reporting schedule for the off-site monitoring stations was commenced at 0700M. All off-site stations contimed to report normal background readings through D+2 days. 6. A reading of 80 mr/hr at H+6 hours at 10,000 feet was obtained by one cloud tracking aircraft 60 miles northeast of BIKINI. The same reading was recorded at H+12 hours by a weather reporting aircraft 300 miles north- east at 30,000 feet. The maximm recorded reading was 110 mr/hr at 10,000 feet, 80 miles northwest of BIKINI at H+l1 hours, - 7. A sharp rise to 3 mr/hr was noted at PARRY Island at 17)5M, 26 June 1956, with an equally sharp decline to background. Two mre peaks were recorded, one of 3.75 mr/hr at 1900M, 26 June, and another of 0.75 mr/hr at 2330M, 26 June. These peaks are attributed to "shine" from the pessing overhead of a radioactive cloud since the decrease was far too repid for decay. DNA
