Anybody remember Glo-Fish?

Apparently, they're growing glow-in-the-dark shrimp now, though not intentionally.

Anyway, I was amused by this:

"It was like a bright eerie light was shining on it," said (Randall) Peters, who works for a natural food store.

"I thought that maybe it had been overirradiated, you know, too much radiation. Now, whenever I buy seafood, I take it home and turn out the lights."

Now, even I have enough basic knowledge of radiation to know that this is NOT a likely explanation. But, since I am so blessed as to have a Cute Nuclear Scientist in my pocket (or on my Flist, which is almost as good), I had to ask for more detail.

so... how much radiation would it take to make a fish (or human) glow in the dark?

funranium responds: "Amounts that would be lethal...to have a high enough concentration to glow visibly on the skin, since tritium distributes evenly in all tissues, would be very lethal...the corpse would glow of course."

But hey, glowing corpses could be fun. Anybody wanna write the script for Radioactive Zombie Shrimp Attack Seattle?
