Dose Summary for Operation ARGUS.
The detonations occurred at such distances above the earth that the
possibilities of personnel exposures to ionizing radiation were considered
remote.
The recorded doses were, in fact, so low as to be negligible.
The
highest level recorded by the 264 film badges distributed to the task force
was 0.010 rem.
The highest level recorded, 0.025 rem, was by a control film
badge, which was not issued to personnel but remained in storage ina
radiation-free area within a ship.
Another control badge read 0.020 rem.
These readings were so low that they probably were spurious and the result of
environmental effects on film emulsions (20: 1,2).
