> Because some people are concerned about biological accumulation of OBT in the environment, we briefly summarize the behavior of OBT in the ecosystem. Scientific data about the environmental behavior of OBT are still limited, however, it is clear that biological accumulation is not the case for tritium including OBT.

"A factory worker ingested tritium over 7.4 years. His exposure dose was estimated at 3–6 Sv. He developed isochromic anemia, and subsequently died of pancytopenia"

Eating tritium straight from the factory for years at a time seems like a special case, yes?

Yes, you can beat the biological half-life if you eat whopping doses of the stuff. That's... not a common situation.

If you ate said factory worker, you'd be back to normal in a couple weeks, as long as you didn't keep eating factory workers.

At a dose factor of 0.000018 mSv/kBq for tritiated water, you would get a 3 Sv dose from "only" 1/5000 of the water.

Drinking (or inhaling) 50,000 gallons of the (undiluted, so best case in terms of volume) water from storage tanks would probably get you with kidney failure somewhat before the tritium does.
