RADIATION EXPOSURE OF PERSONNEL
Since it is the actual radiation exposure to personnel that is of importance, an experi-
ment was cirried aut to compare the whole-body exposurs to that reoelved by the hands.
Measurements were made on the tour personnel who conducted the instrument survey and
the radioautographic studies on approximately eighteen aircraft. The whole-body exposure

measured direc‘ly on the surface. This indicates that the hands of personne) who work
on contaminated aircraft spend little time in close contact with the surface and relatively
more time sway from the surface in a position exposing them to essen*ially the same
vadtation field as the rest of the body
DECAY STUDIES ON CONTAMINATED AIRCRAFT
A record of the intensity of radiation in the crew compartments of the contaminated
B-57's as measured by the T1B was kept. The measurements were begun aa early as
90 minutes after detonation and continued for pericds as long aa 24 hours. The average
slope of the ducay curves was --1.6 with an average deviation of 10.4. A typical decay
