In Japan is sea dilute pollution radiation?

(CNN)-I heard the news today, oh boy: the radioactive water leak at Japan's Quake and nuclear reactor were breastfed tsunami stricken Fukushima Daiichi has. It is the first anniversary of the fatal Massey Energy coal mine explosion. And we are days before the anniversary of the explosion and sinking of the deepwater horizon and the beginning of last year's month-long blowout ordeal. Quite a year for energy. And for the people affected. For example, even if we gave way to long-term disaster best smiley face, pushing one honestly came up a bullet in the Gulf of Mexico last year and the impact of oil not close to matching our fears, that event that hit a season is tourism and fisheries billion cost. So, what's with Fukushima Daiichi? A bit like last year golf blowout, we have to wait until the end of the crisis to start calculation. Fukushima is by no means fixed, but the water leak is currently stopped. So what about the radiation fallout effects on marine life and seafood? First, you see that it not a question of "radiation." We live surrounded by natural radiation. There are "Radiation" in a banana. It is a question of what kind of radiation and how much. Radioactive iodine, widely used in water of Fukushima Daiichi reactors, a half-life of about eight days has. This means that it the half a breakdown and is no longer radioactive after about a week. Other sources have much longer half-lives; radioactive cesium, also from the reactor reduced takes over three decades by half. Complications abound; a low level in sea water in algae can concentrate and then move further enter the food chain.
