There are numerous anecdotes from the USS Reagan that contradict that prosaic interpretation (of the reason it was abruptly moved),

E.g.,
"He was issued iodine tablets—which are used to block radioactive iodine, a common byproduct of uranium fission, from being absorbed by the thyroid gland—and fitted for an NBC (nuclear, biological, chemical) suit. He was also told not to drink water from the ship’s desalination system. [...] Torres, the senior petty officer, recounted, “One of the scariest things I’ve heard in my career was when the commanding officer came over the loudspeaker, and she said, ‘We’ve detected high levels of radiation in the drinking water; I’m securing all the water.’” That included making showers off limits."
I mean I would rather lick a keyboard than a butthole (with exceptions of course)
At any rate 300 is widely recognizable as not an alarming value for a typical contamination detector in a typical configuration, but the report is likely slightly deficient because it does not specify how the measurement was taken. However, even if we accept 100 as the background CPM value, 300 on 100 does not represent significant contamination in a typical environment (but does imply some occurred).
Of course it varies for "civilian" devices from EBay.
They put that count into NRC report. It means that it has pretty specific calibrated meaning for that regulated environment.
>However, even if we accept 100 as the background CPM value, 300 on 100 does not represent significant contamination in a typical environment (but does imply some occurred).
report mentions 300 clearly as something above normal, whatever normal is there. And that is after decontamination. Clearly the source of contamination - the pool - is much higher than 300.
> But just to be sure, I got in touch with a friend of mine who works at a research reactor, and asked him what he thought would happen to you if you tried to swim in their radiation containment pool. “In our reactor?” He thought about it for a moment. “You’d die pretty quickly, before reaching the water, from gunshot wounds.”
