[ RadSafe ] Cesium in Fukushima fish

The Science article is brief and available at the AAAS website or your local library.  (There is not a distinction in the paper as to how much is 137Cs and how much is 134Cs - a bit disappointing in that regard.) 

if you look at this with a little more perspective, you would find that, even if all the fish in one's typical diet of 70 kg/year came only from demersal, near-Fukushima fish (let's say you are a fan of Fukushima halibut, for instance) and was at the Japanese limit of 100 Bq/kg, then you would be consuming a whopping 7,000 Bq of cesium per year (134 plus 137) - this translates to something about 13 mrem/y. 

Given that our unavoidable radiation dose is on the order of 350 mrem/y, eating fish would seem to be more an academic or nutritional exercise than a toxicologic one.   

I plan to visit Japan soon and I will be eating the halibut - I promise a tasty review!
