I don’t. Here’s a statement re tritium. It’s not the original I read but it sounds like the same info.

Sampling detected about 2000 picoCi/l of tritium in the harbor sea water. 20000 picoCi/l is considered safe to drink. By the time the harbor water got 100 miles at sea where the carrier was, it would be undetectable.
