(3) Outer clothing should be reduced to 7 mr/hr. b. Vehicle MPLs. The interior surfaces of occupied sections of vehicles should be reduced to 7 mr/hr. The outside surfaces of vehicles Should be reduced to less than 7 mr/hr (gamma only) at five (5) or six (6) inches from the surface. c. Ship and Boat MPLs (1) It is desired to point out that the employment of the ships and units in TG 7.3, insofar as radiological safety is concerned, is not considered routine usage within the purview of NavMed P-1325, "Radio- logical Safety Regulations". Current revision of NavMed P-1325 indicates that its provisions do not apply for special operations such as field tests and that for such operations naval personnel will operate under regulations set forth by the task force commander as approved by the Chief of Naval Operations. beet (2) In general, ships and boats operating in waters near shot sites after shot times may become contaminated. Monitors shall be aboard all such craft operating after shot time, either as passengers or members of the crew, until such time as radiological restrictions are lifted. (3) Task Group commanders will take necessary action to ensure that Personnel of ships and boats are not over-exposed to radiation and that ships and boats are not contaminated excessively. The criterion in both cases is that no personnel will be over-exposed as defined by Paragraph 5a, above, except in emergencies or tactical operations, and that after the operational period no personnel will receive more than 0.3 roentgens per week from contaminated equipment. (4) For ships and boats operating in contaminated waters, reasonable allowances will be made to differentiate between the relative 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 cm2 of area for enclosed areas (cabins, etc.) and 5000 dpm per 150 em2 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 so ordered. An operational 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. 455
