Declassitied pod DIR 5200.10 b. Vehicle MPL's: (1) _ ~ e The interior surfaces of occupied sections of vehicles should be redifeed to seven (7) mr/hr. The outside of vehicles should be redwed to less than seven (7) mr/ hr, gamma only, at five (5) or six (6) inches from the surface. c. Aircraft MPL's: (1) The interior surfaces of occupied section of aircraft (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 other- should be redwed to seven (7) mr/hr. wise. (Based on maximum predicted yield and twenty (20) mile visibility, Blast (at predicted shock arrival): 0.5 p.s.4. Thermal (H Hour): Fabric control surfaces: 1.0 Cal/em Metal. cant pol surfaces: 6.0 Cal/em After detonation no aircraft shall operate inside the air radex or closer than ten (10) nautical miles from the rising or visible cloud wnless specifically directed otherwise. If a tactical or emergency situation arises where aircraft must enter the air radex, tactical exposure allowances shall apply. (3) All multi-engine Task Force aircraft in the air at H Hour within one hundred (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 allowable exposures under both tactical and operational conditions. (4) 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. (5) Pilots and copilots of aircraft in the alr at shot time shall use modified all-purpose .1 density filter goggles. Copilots should, as an extra precaution, over their eyes with forearm at zero hour. d.
