Autoradiography

I am officially stumped. I am studying the exposure to personnel from Operation Crossroads (Able and Baker bombs). One of the things I have run across is a claim that Warren Stafford proved there was plutonium in the lagoon because a surgeon fish had autoradiographed a film after eating contaminated lagoon algae (the claim is actually from the official photo archive).

What I'm trying to figure out is how to you definitively identify Pu-239 from an autoradiograph in an environment with Pu-239, U-235, and fission products from both?

Am I missing something?

Thanks,

I don't really know. But Plutonium tends to accumulate in bone marrow. So my guess is that the pattern of radiation within the organs of the fish was enough to distinguish Plutonium from other radiation sources.
