However, installation of four cascade impactors was accomplished and
the equipment operated satisfactorily.
The test of the collective protectors was somewhat more complicated
since it was necessary to install some means of measuring the concen-
tration of radioactive materials in the effluent air stream of the
protector.
This was to be accomplished by means of a ratemeter with a
beta sensitive geiger tube in the air stream and an Esterline Angus
Recorder.
The collective protector was powered with a gasoline engine
and the ratemeter with a gasoline driven generator.
Considerable
difficulty was encountered in keeping the gasoline generator operating
over the full 24-hour period required as the equipment had to be
started on the morning of X-Ray-minus—one day and had to operate
continually until after the detonation.
The generators available
were small and not designed for such continuous use,
