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.
