c. Ship and Boat MPLIs:
(1) Ship and boat MPL’s cannot be quantitativelyestablished.
They are dependentupon locationof contamination,

of space,personnelhazard,etc. Specifiedinstructions
will be issuedby CTG 7.3 upon reportingof contand.nation
as requiredby para 2 d. of Appenti 4 to Annex G.
(2) Fe-rahips and boats operatingin contaminatedwaters,

(3) In general,shipe and boats operatingin waters near
shot sites after shot times may beccmnecontaminated.
Monitors shallbe aboard all euch craft operating
after shot time, either as passengersor members of
the crew, until euch time as radiological.
