Radiation from the 2011 disaster at the Fukushima Daiichi nuclear power plant contaminates most Japanese seafood at low levels, researchers estimate February 29 in the Proceedings of the National Academy of Sciences.

For aquatic foods, data on lingering concentrations of cesium is limited in terms of the number of species sampled and the levels that surveys can even detect. To fill in the blanks, a team of researchers in Japan drew from survey measurements from April 2011 to September 2015 and devised a way to predict cesium contamination in different aquatic species across Japan.

Low degrees of radiation from Fukushima persist in seafoodThe analysis provides combined reports: Overall, cesium contamination is certainly fairly low. But, some species keep higher levels than others. Larger fish near to the the surface of the food web tended to really have the highest degrees of contamination. The experts predict that such elements put some crazy freshwater species just like the whitespotted char (Salvelinus leucomaenis leucomaenis) and japan eel (Anguilla japonica) at higher risk for contamination
