decontamination.
The above-described procedures reduced this to 20
mr/hr, an effectiveness of 92 percent when corrected for decay.
In
the washdown srea, which included the superstructure, the initial level
was 115 mr/hr.
Following decontamination the level was 13 mr/hr, an
effectiveness of 78 percent when corrected for decay,
This is in agree~
ment with results obtained in operation CASTLE which showed decreased
decontamination effectiveness following washdown,
The working party of 45 men was divided into 5 & 6 man teams and
expended a total of approximately 15 working hours in the decontamination
of the two ships.
CONCLUSICNS
It is feasitle to decontaminate a ship by means of the procedures
descrited herein,
The effectivenesses reported are probebly higher than would be
obtained in the removal of a more tenecious contaminant,
