The desirability of aircraft pressurization filters seemed somewhat
enhanced when considering the penetration of atomic clouds of this type
and magnitude, especially if the cloud was generated from a surface detonation.
From observing the personnel burns occurring on the downwind ia-
lands and on board naval vessels of the Task Force, it was apparent that
superficial burns due to beta radiation could be produced from unconcentrated fission products in the fall-out.
The concentration of fission
products in an unfiltered aircraft following a cloud penetration was not
measured under the BRAVO conditions, but was considered worth including
in future test planning.
The skin burns as seen were not disabling but ; "

were certainly undesirable.
It was reported by Program 4.0 that as of H plus thirty-nine days
there was no factor present in the blood pictures to indicate any evidence of chronic or internal radiation effects.
Finally, there was still a psychological factor to be considered
when dealing with Department of Defense personnel.
The natives were un-
concerned and carefree about the whole affair, but U. 3. personnel were
shaken by their experiences,
Apparently, they were well educated to the
dangers of contamination, but not to the actual effects.
