State officials have announced that tests of Alaska seafood continue to show no detectable amounts of radiation, five years after a deadly earthquake and tsunami set off a nuclear disaster at a Japanese power plant.
More than 16,000 people were killed in 2011 after Japan's 9.1-magnitude earthquake, which led to nuclear meltdowns at the Fukushima Daiichi nuclear power plant.
Since then, U.S. and international agencies have been conducting tests to determine the health of marine life along the U.S. and Canada, KTVA-TV reported (http://bit.ly/2iZxoG5). Testing regions in Alaska include the Aleutian Islands and Bering Sea, Bristol Bay, the Gulf of Alaska and the southeast region.

It is the old story. Dangerous radioactive materials with fast half-lives give off lots of radiation, but decay very quickly.
Far less dangerous materials that give off tiny amounts of radiation have long half-lives, and last a long time.
The idea that really dangerous radioactive materials last centuries is a myth.
The closed-off region around cherobyl is teeming with healthy wildlife. Hmm. Maybe the critters know something.
There are billions of people in the world, if fewer than 16,000 had died between March of 2011 and the start of 2012, it would be pretty unusual. The fact that more of them died in that time is not remarkable.
I think they found some bacterium or a fungus that eats radiation a few years ago. They just found one that eats plastic, too. Also, Oil is a favorite food of another bug. There is nothing to worry about!
A nuclear scientist could have told them that. Radioactive particles still have their chemical properties. As a rule of thumb, the lighter they are, the more able they are to travel, because the heavier ones sink in the air or water.
Lighter isotopes also generally have shorter half lives, so they can’t travel too far before they are no longer radioactive. The most dangerous isotopes are the medium sized ones, especially if of elements that are easily absorbed by plants and animals. But in addition to everything else, they tend to disperse.
You likely have some of these in your body, but too few to even notice.
In any event, the Pacific Ocean has about 180 million cubic miles of water. However much medium sized radioactive particles released from Japan would be spread out in this.
US has unintentionally sunk two nuclear sub reactors in the ocean. Soviets sunk a lot more between accidents and just dumping old naval reactors in the arctic ocean. Doesn’t get near as much attention as Chernobyl or Fukushima, but certainly is significant.
