Do you think that the Captain of the ship would have put those sailors in harm's way on purpose? The radiation dosage they received certainly was NOT planned or expected, or those men NEVER would have ben exposed to it! That means the amount of radiation at Fukushima was not admitted by the Japanese - and that makes it extremely relevent, especially in trying to determine the amount that could reach America.
As for the rest, you are the one play-acting here. And you're doing it to minimize the extremely alarming and highly significant severe radiation poisoning of those sailors, which under no possible means was "expected."

You are comparing apples to oranges. Do you not understand the difference between a ship just offshore of Fukashima and
the American west coast, 6000 miles away? The water is not going to be radioactive, and chunks of radioactive debris are not going to be washing up on the US west coast shores.
