Just my 2 cents worth....
these AN/PDR-70's are still being used, in particular with Navy Nuclear
contractors.... interestingly enough, with the weight approaching 30 lbs.,
they are able to float for about 5 minutes, but are useless after they sink.

Kim,

I recall the AN/PDR-70 being referred to as a "Snoopy".  The detector is a
proportional counter filled with boron trifluoride gas. The shield consists
of
concentric cylinders; with the inner cyclinder being polyethylene, followed
by
boron impregnated plastic and finally by more polyethylene.  You might find
some of these relics at older nuclear facilities.
