Fish From Japan Contain Unsafe Levels Of Radioactivity

TOKYO — Elevated levels of cesium still detected in fish off the Fukushima coast of Japan suggest that radioactive particles from last year’s nuclear disaster have accumulated on the seafloor and could contaminate sea life for decades, according to new research. Because cesium tends not to stay very long in the tissues of saltwater fish — and because high radiation levels have been detected most often in bottom-feeding fish — it is likely that fish are being newly contaminated by cesium on the seabed, Mr. Buesseler wrote in the Science article. As much as four-fifths of the radioactive substances released from the Fukushima Daiichi nuclear power plant are thought to have entered the sea, either blown offshore or released directly into the ocean from water used to cool the site’s reactors in the wake of the accident.Sea currents quickly dispersed that radioactivity, and seawater readings off the Fukushima shore returned to near-normal levels. But fish caught in the area continue to show elevated readings for radioactive cesium, which is associated with an increased risk of cancer in humans.

How does this affect us you may wonder. If you eat fish you could be affected. We get a large supply of our seafood from Japan and as we know there aren’t any levels of radiation that is safe for humans. Since you can’t be 100% certain where the fish you’re eating is coming from your best bet would be to greatly limit your fish consumption.
