The following is an estimite of results obtained from various

Gamma Radiation vs Distance
Exposed filns were recovered intact fron Muzin and Karinian Islands
~
(2200-1000 yds), Lost of the canpletely exposed films on Engebi were
=
destroyed due to ignition of the aluminum foil covering but a few which
apo
i
had not been too greatly damaged were recovered and may provide occasional
values,
However, many films were recovered which had been given only
small amounts of steel shielding (2") and these should be quite satisfactory for determining the gamma radiation as a function of distance
,
s
after a slight correction has been applied,
All films have been returned
to Dr, Taylor at National Bureau of Standards for development and final
results are not yet available.
In Test Yoke a thin shield with an air
space between it and the film was placed in front of the film badge in
ve
order to avoid ignition of the aluminum foil,
