How was the ocean affected by Fukushima?
Japan has approved a plan to release more than one million tonnes of contaminated water from the destroyed Fukushima nuclear plant into the sea. The water will be treated and diluted so radiation levels are below those set for drinking water.
How much radiation did Fukushima release into the ocean?
According to a report published in October 2011 by the French Institute for Radiological Protection and Nuclear Safety, between 21 March and mid-July around 2.7 × 1016 Bq of caesium-137 (about 8.4 kg) entered the ocean, about 82 percent having flowed into the sea before 8 April.
Is it safe to eat fish after Fukushima?
A study clears most seafood from any dangerous health effect five years after the nuclear disaster. Nearly five years after the Fukushima Daiichi nuclear disaster, most seafood caught off the coast of Japan is safe to eat, according to a new study.
How does radiation affect marine life?
Once in seawater, radiation can hurt ocean animals in several ways—by killing them outright, creating “bizarre mutations” in their offspring, or passing radioactive material up the food chain, according to Joseph Rachlin, director of Lehman College’s Laboratory for Marine and Estuarine Research in New York City.
How bad is the radiation from Fukushima?
Research from the Woods Hole Oceanographic Institute registered radiation levels in the ocean near the Fukushima reactors “50 million times higher than before the accident,” what they called “a threat to marine life.” A study in 2019 found that radionuclide levels in fish off the coast of Fukushima are variable, but …
Does salt absorb radiation?
Iodized table salt should not be used as protection against radioactive fallout. But you’d have to consume 3 1/2 pounds of iodized salt to obtain the 130 milligrams of iodine that’s contained in a single tablet of potassium iodide for use in a radiation emergency, according to the Salt Institute.
