the surface radex in which rescue operations will be carriedfout without regard to the radiological hazard. Monitors aboard veccile craft shall be required to determine the extent of the actual radidtion hazard experienced in order that appropriate medical tests mayfbe initiated. For emergency operations, the criteria prescribed for factical situation (para. 13 below) will be used as a guide. For opegational purposes the MPLs presented below will not be considered appfJicable to spotty contamination provided such areas can be effectively Jsolated from personnel. a. Personnel and clothing MPLs are as follows: (1) Skin readings should not be more than 1 mr/hr. Compl te decontamination by bathing will be utilized for readings in exces level. Beta radiation exposure to the hands should not exce rep/week. (2) Underclothing and body equipment such as the internalf surfaces of respirators should be reduced to 2 mr/hr. (3) Outer clothing should be reduced to 7 mr/hr. b. Vehicle MPLs: The interior surfaces of occupied section of vehicles should be reduced to 7 mr/hr. The outside surfaces of ehicles 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) Operational clearances, implying that contamination special procedures are required, will normally be granted b ing officers on the technical advice of radiological defens members. In peacetime, a maximum fixed contamination level mr/week ordinarily will not be exceeded except for "Operati sity". For this operation an MPL of 600 mr/week will be us upper limit for "operational necessity" unless otherwise sp ifically raised or lowered. Fixed alpha contamination should not ex eed 500 cpm (counts per minute) per 150 em* of area. (2) For ships and boats operating in contaminated waters reasonable allowances will be made to differentiate between the r lative contribution to the total flux from fixed contamination and that due to "shine" from contaminated waters. For this operation it will be assumed that not more than ten percent of the radiation flu entering the vessel through the sides is due to contamination which ill remain Ships and fixed on the vessel upon reentry to uncontaminated waters. boats encountering levels of contamination greater than det rmined by the above will request special instructions. (3) Final clearances, normally granted by commanding off cers, be given upon completion of the operation provided no point of contamination is greater than 15 mr/day (beta and gamma) an no detectable alpha exists. 442 will
