SECTION VI
ROUTINE RADIATION EXPOSURES
Background
’ The Atomic Energy Commission has adopted, as an operational guide,
3.9 roentgens whole body external gamma radiation for off-site exposures
resulting from Operation Plumbbob.
The discussion in Section I on effects of weathering and shielding
on determining the actual radiation exposure is applicable here.
However,
the factor of biological repair is not considered for routine exposures.
_This factor bears on somatic effects and may justifiably be cons&dered in
emergency situations when it is necessary to weigh the relative hazards
fron radiation versus mass evacuation.
However, for routine exposures,
the actual (estimated) roentgen dose should be used.
To distinguish from
the Ertective Bioisgical Dose and the Infinity Dose, this exposure will
be excressed as the =Zstimated Dose.
Gravn V incorzcorates the assumed effects of weathering and of
Shielding accoréing to the discussion in Section I.
