Creepy signs the radiation from Fukushima is contaminating the West Coast

[True Federalist (진정한 연방 주의자)]

While Fukushima is a problem, the article linked to in the original post is to a scare site.  Take for example the Vancouver Sun report that is linked at that site.  What the newspaper article makes at least somewhat clear is that while high numbers of imported Japanese fish are showing some ¹³⁷Cs contamination, only a very few are doing so at high levels (≥ 1 Bq/g)  Given the biological half life of cesium and and the results of a 1972 on dog mortality from high levels ¹³⁷Cs (considerably higher than in these fish), you'd be need to be eating nothing but Fukushima caught sashimi to be in any serious risk.

Plus there are plenty of chemical poisons to be worried about.  I'd be more concerned about the effects of pollution from Chinese industry than from  Fukushima on the health of sea life off the North American coast simply because those are far larger in quantity.

If large numbers of prey are contaminated, the toxins build up until the predator dies from poisoning. #APEnviroScience

Very true, however, cesium is not a heavy metal.  The biological half-life of cesium is far shorter than that of lead, cadmium, or plutonium.  Cesium's is measured in days, the other metals I just mentioned have biological half-lives measured in years.  And if your really worried about cesium contamination, just take some Prussian blue to help flush cesium (and some other metals) from the body.

Hopefully the radiation spreads to spiders.

Seconded. F[inks] spiders.

...I was making a Spiderman reference.

Well I was saying that I want all spiders to die.

Why? Spiders can be quite helpful and won't usually harm humans. Wasps, on the other hand...

Misogynist.
