> Unlike chemical contamination (e.g. mercury) radiation doesn't bio-accumulate.

That is a very, very misinformed or misleading statement. Caesium-137 and Strontium-90 have half lives of around 30 years and do get into seafood. There are warnings given out often about radioactive contaminated seafood. That's why Fukushima's radioactive water dumping was such a problem and neighboring countries had issues with it.

Seafood can and does get radioactive contamination and this increases cancer risks in humans that consume it.
