all cases other than emergencies or tectical situations, the ultimate
criteria will be linited by the MPEs for personnel, Special instances may
arise such as in the case of an air-sea rescue within the Radex, or in the

tactical operations the criteria prescribed below for tactical situations
will be used as a guide.
Wherever.possible, however, film badges will be
carried and KedSefe monitors will accompany such operations to determine
the extent of the aetucl radiation hazard experienced in order that.
appropriate medical action may be initiated,
