(1) Operational clearances, implying that contamination
and special procedures are required, will normally be grante
commanding officers on the technical advice of radiological
staff memberse In peacetime, a maximum fixed contamination
300 mr/week ordinarily will not be exceeded except for”
"Operational Necessity". For this operation an MPLof 600 x
will be used as the upper limit for "operational necessity"
otherwise specifically raised or lowerede
Fixed alpha cgna
should not exceed 500 cpm (counts per“minute) Per 130 cn”0
(2) For ships and boats operating in contaminated waters
able allowances will be made to differentiate between there
contribution to the total flux from fixed contamination and
to "shine" from contaminated waterse For this” operation it
assumed that not more than ten percentof the radiation,flu
the vessel through the sides is due to contamination which, w
main fixed on the vessel upon reentry to uncontaminated wate
and boats encountering levels of contamination greater than
mined by the above will request Special instructionse os
(3) Final clearances, normally granted by commanding off
will be given upon completion of the operation provided no p
contamination is greater than 15 mr/day (beta«and
4 gama) and
detectable alpha exists.
