etege (7) No ships with personnel shall be permitted inside the 1.5 p.s.i. line unless specifically directed otherwise. Bearings of danger from immediate radioactive fall-out for ship operations will be established by CUJTF SEVEN on the basis of forecast wind directions at the intended time of detonation. This danger section will be designated as surface RADEX. All ships of the task force shall be required to remain outSide the RADEX - danger bearing, radial limitation and time restriction unless specifically directed otherwise. However, if ships are directed tactically into the surface RADEX, movement of ships shall be governed by tactical exposure guides. d. Aircraft (1) The interior surfaces of occupied sections of aircraft should be reduced to 7 mr/hr. (2) No aircraft in the air at H hour will be at slant ranges from ground zero less than as determined by the following effects unless specifically directed otherwise. (Based on maximum predicted yield and 20 mile visibility). Blast (at predicted shock arrival): Thermal (3) (H Hour): 0.5 p.s.i. Fabric control surfaces: Metal control surfaces: 1.0 cal/cm2 6.0 cal/cm? After detonation no aircraft shall operate inside the air RADEX or closer than 10 nautical miles from the rising or visible cloud unless specifically directed otherwise. Non-excepted aircraft involved in routine operations encountering unexpected regions of aerial contamination will, immediately upon ‘detecting such contamination, execute a turnout. Cloud tracking aircraft will execute turnout from contaminated areas at a level of not more than 3.0 r/hr. If a tactical or emergency situation arises where aircraft must enter the air RADEX or visible cloud, tactical exposure allowances shall apply. (4) All multi~engine task force aircraft in the air at H Hour within 100 miles of the detonation point shall carry a person designated as radiological safety monitor, equipped with suitable radiac equipment and a RADEX plot. This monitor shall be capable of calculating allow- able exposures under both tactical and operational conditions. (5) All persons in aircraft at shot time or at subsequent times when engaged in operations in or near the cloud or RADEX track shall wear film badges. (6) Crew members of aircraft in the air at zero hour will take special precautions to avoid (for at least 10 seconds) the direct and reflected light resulting from the burst. At the discretion of the airplane commander this could be done with protective high density goggles, by turning away from the burst with eyes closed, by covering the eyes with the forearm, by turning the cockpit lights up to highest intensity or by any combination of the above. 456
