The derived intervention levels instituted by the FDA for food are outrageous, 160 BQ per KILO for strontium and 1200 BQ per KILO for Cesium. I personally do not want any detectable levels of cesium in my food. And I certainly would not want detectable levels of strontium in my food. Perhaps by tweaking logic a bit one can compare cesium laced food to a banana. With strontium one can make no such comparisons. The strontium goes to one's bones and hangs around. The biological half life for strontium is much longer than the half life for Cesium.
MILES O’BRIEN: In New York, at Stony Brook University, Nicholas Fisher is focused on radioactivity in fish. He studies the ultimate sushi delicacy, bluefin tuna. These amazing creatures spawn near Japan, migrate to California, then return to Japan. He measured tuna caught in San Diego four months after the meltdowns.
NICHOLAS FISHER: We were quite surprised to see that every single fish we analyzed had clear evidence of Fukushima-derived radionuclides in their tissue.

Chances are if one is to eat Pacific seafood, one is eating tainted seafood. Now the argument over whether food is safe or not is relative. If one consumes food tainted with cesium, one becomes tainted themselves. Given the choice between a clean McDonald's cheeseburger and a tainted Tuna, I am taking the cheeseburger. And we are not even really testing the seafood. THis means one also has to worry about strontium or perhaps getting fish with a hot dose of radiation. The claim that Pacific fish is safe is spurious without proper testing.
We are also having report after report of sick sea creatures--sea lions with abscesses, emaciated killer whales, dying starfish, chunks missing from salmon and on and on.
Researchers developed a model based on the diet of fish-eating killer whales along with the levels of Cesium 137 detected and predicted (less than 0.5 becquerels per cubic metre, a measurement of radioactivity) by other researchers in the Pacific waters offshore of Vancouver Island.
The models suggest that in 30 years, Cesium 137 levels in the whales will exceed the Canadian guideline of 1,000 becquerels per kilogram for consumption of seafood by humans - 10 times the Japanese guideline.

I don't see how ISIS is a threat to the USA, and I certainly see no threat from Putin and Russia. We have two oceans to protect us from anybody invading. And I don't think anybody is all that worried about Canada and Mexico. And the vast resources we have already wasted here have brought us dubious results.
A contaminated Pacific ocean is a threat. We should be directing our resources towards trying to save it. We should not be wasting our resources against pseudo threats and address the real threats. Perhaps nothing can be done, but we need to direct more resources at Fukushima.
