CJTF SEVEN No. 3-53
contribution to the total flux from fixed contamination and that due
to "Shine" from contaminated waters. Fixed alpha contamination
should not exceed 2500 dpm(disintegrations per minute) per 150 em2
of area for enclosed areas (cabins, etc.) and 5000 dpm per 150 cm
area for open surfaces where ventilation is good,
(5) At the conclusion of the operation, final clearances will be
granted by task group commanders or by commanding officers, if so
ordered, to those ships and boats showing no point of contamination
greater than 15 mr/day (beta and gamma) and no detectable alpha.
Other ships and boats will be granted operational clearances by task
group commanders or by commanding officers, if sc ordered. An opera-
tional clearance implies that contamination exists and that special
procedures as necessary are instituted aboard ship.
(6) Individuals on board ships of the task force shall be protected collectively from hazards of blast, heat and radioactivity by
movement and positioning of the ships.
(7) No ships with personnel shall be permitted inside the 1.5
posoi. line unless specifically directed otherwise. Bearings of danger from immediate radioactive fall-out for ship operations will be
established by CJTF 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,

Aircraft MPLs
(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): 0.5 p.a.d.
Thermal (H Hour): Fabric control surfaces: 1.0 cal/cm®
Metal control surfaces:
6.0 cal/em
(3) 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 rhr.
If a tactical or emergency situation arises where aircraft mst
enter the air RADEX or visible cloud, tactical exposure allowances
shall apply.
(4) All miti-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
