Low levels of Fukushima cesium found in West Coast tuna

Scientists hope to test new samples of Pacific bluefin tuna after low levels of radioactive cesium from Japan's Fukushima Daiichi nuclear accident turned up in fish caught off California in 2011, researchers reported Monday.

The bluefin spawn off Japan, and many migrate across the Pacific Ocean. Tissue samples taken from 15 bluefin caught in August, five months after the meltdowns at Fukushima Daiichi, all contained reactor byproducts cesium-134 and cesium-137 at levels that produced radiation about 3% higher than natural background sources – but well below levels considered dangerous for human consumption, the researchers say.

Cesium-137 has a radioactive half-life of about 30 years, and traces of the isotope still persist from above-ground nuclear bomb tests in the 1950s and '60s. But cesium-134, which has a half-life of only two years, "is inarguably from Fukushima Daiichi," Stanford University marine ecologist Dan Madigan told CNN.

    Don't do it ...radiation has entered the food chain... pick out wisely what you eat....I would buy a small geiger counter for the home a let that be your measuring stick!

    I used to eat quite a bit of raw fish. Now I stick with vegtables instead.

    Whats to worry about here? Ann Coulter said radiation is good for you.....

    Sadly I fear this is just the beginning, fish that will make there way here have spent longer periods of time in the radioactive contamination... still the reactors are spewing out radiation, solidly for 1 year... and unit 4 is crippled and could collapse, if it does, it will ignite the spent fuel rods.. and that would be incredibly harmful.. a mega disaster.

    One great diet exercise is eating low carbs food, fruits, fishes and vegetables, or you might try the vegetarian program of some of our elders. This helps you a lot in reducing your weight as well.

    I have some recommendations also, try this one http://www.paleodietguru.com , this might help you also.

    @Mark, that's what I am talking about. Keep it up as that is a healthy habit whereas you are the only beneficiary of what you are doing right now.

    Much fish used for Sushi today is farm raised. One can debate which is the better choice.
