I don't know what today's Navy ships have by way of always-on ambient radiation detectors, and to be honest I don't remember exactly what we had in my day; I'm sure I learned it while qualifying, but my day-to-day duties were in other areas. I can say that even in my day we were constantly monitoring ambient conditions -- and one of the things we constantly drummed into each other was to look for trends, not just instantaneous readings (life isn't a snapshot, it's a movie).
