Every bluefin tuna caught in California waters is believed to be contaminated with radiation that originated in Fukushima, according to a new report. Are the levels of radiation for the bluefin tuna in California worse this year than last?

In May of 2012, the Wall Street Journal reported on a Stanford University study by Daniel Madigan, a marine ecologist who was quoted as saying:

"The tuna packaged it up (the radiation) and brought it across the ocean ... we were surprised to see it at all and even more surprised to see it in every one."

Another member of the study group added that "absolutely every one" of the tuna had comparable concentrations of cesium 134 and cesium 137, The Hollywood Gossip reports.

That was over a year ago, when the fish had relatively little exposure to the radioactive waste being dumped into the ocean following the 2011 nuclear disaster in Fukushima.

Since that time, the flow of radioactive contaminants has not let up nor been reduced. Now, bluefin tuna fish born in California waters have been swimming in radiation contaminants for all of their lives.

According to The Hollywood Gossip, radioactive cesium doesn't sink to the bottom, so fish swim through it, ingest it through their gills, or eat organisms that have already been contaminated by the radiation.

Though the radioactive compound occurs in nature, the levels of cesium found in the California bluefin tuna in 2012 had levels that were 3 percent higher than what is normally found in nature.

So does this mean with all the levels of radiation exposure since 2012, the bluefin tuna fish, as well as other fish in California, have radiation levels higher than before?

We can't be certain, since radiation measurements for this year haven't been made available, The Hollywood Gossip reports.

Common side effects of a person who has been exposed to radiation of the cesium particles includes nausea, vomiting, diarrhea and bleeding. When the exposure lasts a long time, people may even lose consciousness, the website notes.
