The mission was accomplished in less than two hours DELETED The monitor AEA Restricted Data then returned to the AVR and accompanied an unscheduled water cable party. No samples were found either afloat or on the bottom of the lagoon, as far as could be seen. Since the party went quite close to the zero point in the water, considerably more exposure was the result. However, the total received was well within the tolerance established. More of the missing samples were recovered in later trips to the island. Strategic Plot Center STRATEGIC PLOT maintained a fall-out chart of the lagoon, DELETED The Eniwetok atoll chart AEA Restricted Data was kept up to date as reports came in and an iso-intensity line of 0.1 r per day in the lagoon water was also plotted on this chart. The surface and air radexes were plotted daily from weather data obtained from Aerology. Utilizing a vector analysis of the wind velocities, tall-out patterns for the surface, 15,000, 20,000, 25,000 and 30,000 feet weredetermined. These patterns were plotted on charts with a superimposed polar grid. From the fall-out patterns, the surface radex, given as two bearings from zero point, and also recommendations as to the direction of the third pass for each drone plane mother were determined. Definite eriteria were used to determine whether or not the DELETED AEA Restricted Data Bseériod i us ei PRIVACY ACT MATERIAL REMOVED
