9. All samples of radioactive material
which are ouriered in aircraft
will be packaged and loaded so as to reduce radiation to a minimum. The
Rad-Safe Officer of TG 7.4 will have a survey made of the package to
determine if adequate precautions have been taken.
will determine space and packaging requirements:
The following criteria
a.
Prior exposure of aircraft and courier personnel.
b.
Anticipated future exposures on trip.
c.
Length of time of exposure on trip.
d.
In all cases, crew members will be limited to exposure rates
of less than twenty (20) mr/nr.

._ll. The Maximm Permissible Limits (MPL's) of contamination listed
‘ferein are to be regarded as advisory limits for cmtrol of contamination
under average conditions, and are subject to revision by waiver from the
fask Force Commander in individually designated cases when extenuating
circumstances indicate the need and justification therefor. All readings
of surface contamination are to be mde with Geiger coynters, with tube
walls not substantially in excess of thirty (30) mg/cm* with shield open.
The surface of the probe should be held one (1) inch to two. (2) inches

operations will be carried out without regardto the radiological hazard.
Monitors aboard rescue craft shall be required to determine the extent of
the actual radiation hazard experienced in order that appropriate medical
test may be initiated. For emergency operations, the criteria prescribed
for tactical situation (par 12 below) will be used as a guide. For
operational purposes the MPL's presented below will not be considered
applicable to spotty contamination provided such areas can be effectively
isolated from personnel.
a.
Personnel and clothing MPL's are as follows:
(1)
Skin readings should not.be more than one (1) mr/hr.
Complete decontamination by bathing will be utilized
for readings in excess of this level.
Beta radiation

exposure to the hands should not exceed 30.0 rep/week.
(2)
Underclothing and body equipment such as the internal.
ournaces of respirators should be reduced to two (2)
mr/hr.
(3) Outer clothing should be reduced to seven (7) mr/hr.
