>> Back in the 80’s & 90’s it was 300 milli rem per 7 days.
In my Navy NUC days (637 class SSN), if I remember correctly the limit was something like 100mrem/week — and as I recall, even working back aft we seldom received more than 15mrem/week during normal at-sea ops.
We all wore TLDs and (again IIRC) they were read weekly.
The biggest short-term dose I ever got was a couple times working in the reactor compartment for a little while (hour or so) — after being shut down for some time, of course. Don’t even remember what that dose was but no more than a few tens of mrem, I think.
I confess I may be fuzzy on the numbers — it was quite awhile ago (late 70s).
My brother received training on Treasure Island in the 70’s while in the Navy, six years ago he almost died from a brain tumor growing around his brain stem. Now I have to wonder if there is a cause and effect.
By law occupational dose for a “radiation worker” meaning someone who works in an industry where they might be occupationally exposed to ionizing radiation has a dose
limit of 1.25 R per calender quarter and a maximum dose of
5R per calender year. Some employers can and do break that dose down into weekly or daily limits. That is acceptable as long as the cumulative dose does not exceed the legal limits of 1.25R/qtr or 5R.yr.
NON occupational exposure is limited to 10% of occupational
exposure. This means that a secretary working in such a place cannot recieve more than 125mr/qtr or 500mr/yr. In addition there are further limits placed on occupational workers who are pregnant.
This story seems fishy. I doubt that much exposure is being generated “in the wild”.
I developed neuropathy in both feet, followed by gross hematuria, and escaped colon cancer by the narrowest of margins. My Dr said I got really lucky...
Give it a couple more years and you'll be used to it.

shhhh...
I will concede that this is a wait and see as to how all this progresses. My father would have said, “I’ve seen sicker dogs get well, but I don’t know when”.
What boat?
