Air Radex. For H+l, 10,000 feet (3.05 km) to 40,000 feet (12.19 km), 225° clockwise to 290° from ground zero for a maximum distance of 25 nmi (46 km), 290° clockwise to 30° for a maximum distance of 20 nmi (37 km), 30° clockwise to 100° for a maximum distance 30 nmi (56 km), and 100° clockwise to 225° for a maximum distance of 5 nmi (9.3 km). For H+l, 40,000 feet (12.19 km) and up, 230° clockwise to 320° from ground zero for a maximum distance of 30 nmi (56 km), 320° clockwise to 50° for a maximum distance of 15 nmi (27.8 km), 50° clockwise to 115° for a maximum distance of 55 nmi (102 km), and 115° clockwise to 230° for a maximum distance of 15 nmi For H+6, 10,000 feet (3.05 km) (27.8 km). to 40,000 feet (12.19 km), 245° clockwise to 290° from ground zero for a maxi- mum distance of 110 nmi (204 km), 290° clockwise to 30° for a maximum distance of 75 nmi (139 km), and 30° clock- wise to 85° for a maximum distance of 130 nmi (241 km). For H+6, 40,000 feet (12.19 km) and up, 230° clockwise to 320° from ground zero for a maximum distance of 110 nmi (204 km) and 50° clockwise to 115° for a maximum distance of 250 nmi (463 km). Command briefings at 1830 and at midnight confirmed the favora le weather predictions for shot time. The forecast fallout pattern, bas@d on the midnight briefing, is shown in Figure 85. The task force flee was located east-southeast of ground zero at 25 to 35 nmi (46 to 65 km] * rad- safe recommended that the slower ships move to 50 nmi (93 km) on a bearing of 120° and that the other ships move south after the H-hour firing re- quirements were completed.
