It is desired to point out that the employment of the ships and
units in TG 7.3, insofar as radiological safety is concern d, is not
considered routine usage within the purview of NavMed P-13 iS, "Radiological Safety Regulations".
Current revision of NavMed P -1325 indicates that its provisions do not apply for special operati Ins such as
field tests and that for such operations naval personnel w [ll operate
under regulations set forth by the task force commander as approved by
the Chief of Naval Operations.
