how do you come up with the idea to test migratory tuna for radiation? brilliant!

Not surprising-given that we have instruments that can detect tiny amounts of radiation that are no health threat.

The real health threat to our health is the millions of tons of mercury, cadmium and other toxic metals and material that China dumps into the Pacific and the atmosphere every year.

So .. how much of these two isotopes of Caesium were found in the tuna?

Is the Caesium a threat to the tuna? Is the Caesium a threat to humans, if the tuna were to be consumed?

The Caesium 134 has a rather short half-life of about 2 years, and the Caesium 137 has a somewhat longer half-life of about 30 years.

All-in-all, it's not clear what the Stanford folks have found out that should concern us.

How do we know the radiation came from Japan and not a PG&E nuke plant?
